| Although roll forming of high-quality GL Galvanized Steel Coil is the most commonly used colored plate forming method, for the production of roof panels and wall panels, there may be a need for blank holder or other accessories, sometimes also need to be as large as possible to improve the bending part of the bending radius. It is also important to avoid scratches on the coating surface during the blanking process, which can be avoided by applying polyurethane or hard plastic to the die. Proper die clearance should be maintained during the pressing of GL galvanized steel coil. Embossing is also a type of color-coated plate forming, the embossing process to ensure that the coating and coating are not damaged, in order to ensure that the color painted plate durability is not affected, also need a low enough embossing sharpness and depth. Stamping, grooving, and punching are other forming methods of the painted plate. For these molding methods, the influence of many factors discussed previously, such as mold clearance and paint flexibility, is also important. For example, stamping methods are used to produce roofing corrugated panels for use in rural areas. The following awareness and care must be taken in the field construction of GL galvanized steel coils to ensure the good performance of the painted steel plates. Handling abrasions usually present as scratches or backside paint particles adhering to the surface of the painted steel plate. Defects arise from poor handling, inadequate paint curing, and irregular surface conditions. Degree of solidification, hardness, and lubricity of paint affect abrasion defects. Good roller lubrication and a suitable back coat will help to reduce abrasions. Sometimes a transparent, strippable film can be applied to the surface of the steel plate to avoid handling abrasions. Scrapes may occur in the hoisting in the baling factory. In order to avoid scrapes caused by bending, the hoisting equipment of long bales should be able to support most of the length of bales. Bundles must be fixed vertically and horizontally. Direct contact with other objects, such as structural parts, must be avoided when transporting GL galvanized steel coils in vehicles. When using forklifts to carry, care must be taken to ensure that the bales do not bend excessively or cause steel plate abrasions. | ||

| Aluminized zinc coil, also known as aluminized steel coil. It is also called high quality galvalume steel coating steel coil or hot dip aluminized coil. Aluminized steel coil is aluminum-silicon alloy coated steel coil, in which the content of aluminum is 90%, silicon 10%. Aluminized steel coil has good heat resistance, heat reflection, and corrosion resistance, and its mechanical and physical properties are better than cold-rolled steel coil. Because of the superior performance of the aluminized steel coil, it has been widely used in our daily products. Such as car muffler, household appliances and so on. USES for aluminized zinc coils Car parts, thermal equipment, building materials, etc. Aluminized zinc coil is called "hot dip aluminum coil ", which is similar to hot dip galvanized steel coil in the manufacturing process. But its heat resistance is better than galvanized steel. Currently, only South Korean and Japanese steel mills can produce the product in Asia. According to the different USES, in order to further enhance the corrosion resistance of materials, there are also special specification products through surface post-treatment (chromate treatment, no (hexavalent) chromate treatment). Characteristics of aluminized zinc coil 1. High-temperature resistance: because of the specific combination of steel coil substrate and coating organization, the formation of an iron-aluminum alloy, so that the GL Galvalumed Steel Coil made in China has excellent high-temperature resistance. Extremely high reflectivity is guaranteed at 450℃. At higher than 480℃, coating appearance gray. When the temperature is up to 650℃, the protective layer to prevent the oxidation of the steel coil is still well preserved without any shedding. 2. Thermal reflection: at 480 degrees Celsius high temperature, an aluminum coil can reflect 80% of the incoming heat. Therefore, aluminized coils can be made into efficient insulation barriers or heat reflectors for high-temperature applications, which rapidly increase the temperature in the furnace through effective heat reflection. 3. Mechanical strength: at room temperature, the mechanical strength of the aluminum coil is consistent with that of the substrate. At the same temperature of 480℃, the strength of the aluminized steel coil is 10 times that of aluminum coil, so the thickness of the steel coil can be reduced by at least 30%. 4. Corrosion resistance: in the process of hot-dip plating, molten aluminum immediately react with oxygen in the air to form a layer of Al2O3 protective layer, so that the surface of the steel coil immediately passivation. This protective layer is very stable and does not dissolve in water. Even if the surface of the steel coil is scratched later, this protective layer can heal itself. Therefore, aluminum zinc steel coil in stock has strong corrosion resistance to chemical corrosion. | ||
| add to favorites | Effect of Surface Finishing of Galvanized Steel Sheet | Cars |
| After China Wave Type Galvanized Corrugated Steel Sheet is finished, it has a great effect on surface quality improvement and performance improvement. There are mainly the following aspects: 1. Improve the surface flatness of the galvanized sheet. After finishing, the flatness of the galvanized sheet is improved, the wave shape of the galvanized sheet is partially eliminated, and the slag particles or other uneven spots on the surface can be flattened to make the surface of the galvanized steel sheet become Smooth and flat. 2. Adjust the roughness of the surface of Wave Type Galvanized Corrugated Steel Sheet. By controlling the roughness of the surface of the work rolls of the finishing machine, the uneven roughness of the surface of the galvanized steel sheet can be unified to a certain range. This improves the paintability of the product and the lubricity during processing. 3. Improve the surface color of the Galvanized Corrugated Steel Sheet. For small zinc flower and zinc-free flower products, the galvanized sheet can be made to have a more uniform surface with a uniform gloss. For some private enterprises, the use of large zinc flower products as color-coated substrates can make the zinc flower bumps and different glosses formed by the large zinc flower crystals smooth and uniform, which makes the zinc flowers blurred and unfavorable. Cover the zinc flower when painting. 4. Improve the processing performance of Wave Type Galvanized Corrugated Steel Sheet. By finishing, the yielding platform of the galvanized steel sheet can be eliminated or become inconspicuous, and the metal slip line can be prevented from being generated in the subsequent processing. | ||

| The surface of low cost galvalumed steel plate is characteristic of smooth, flat and rich star flowers, and the base color is silver white. The coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon. The production technology of aluminizing zinc is similar to that of the galvanizing steel plate and aluminizing plate. The 55% al - Zn alloy coating has superior corrosion resistance when both sides are exposed in the same environment. The 55% al - Zn alloy coating has not only excellent corrosion resistance but also excellent adhesion and flexibility. The long-term corrosion resistance of metal coating products mainly depends on the melting rate of coating and coating thickness, the melting rate of galvanized steel plating is higher than that of 55% aluminum-zinc alloy coating. Therefore, the service life of 55% al - Zn alloy coating is longer than galvanized steel plate. Galvalume steel plate is similar to the silver-white beautiful appearance of the galvanized steel plate and excellent appearance and processing, especially in the steel plate rarely appear processing part crack, the processing part durability is more excellent. In addition, the heat resistance is far better than the galvanized steel plate, thermal reflection than galvanized steel plate more than two times. Uncoated products used in the roof and partition plate can get the effect of energy saving. Aluminum plating zinc plating layer coating adhesion is relatively good, and therefore without Weathering such as pretreatment, can also directly coated on the advertisement board and usually use plank. | ||

| add to favorites | Steel Coil Processing Method | Cars - Economy cars |
| According to the variety and specifications of raw materials and products, there are slight differences. Process pickling When aluminum zinc steel coil in stock is placed, it is easy to form an iron oxide with air if it is not treated, because the air is humid, and rust will occur over a long period of time. Therefore, the surface of the hot-rolled coil should be removed by a continuous pickling unit. The acid used to use sulfuric acid, and now more hydrochloric acid. Before pickling, it is welded and rolled first, and some are also continuously "black annealed". After pickling, it is washed, dried, trimmed, and divided. Cold rolling The pickled strip is rolled to a finished thickness on a cold rolling mill, generally without intermediate annealing. The total compression ratio of the cold rolling of the five-stand continuous rolling mill is generally 60-80%, and the main rolling thickness is 0.3 to 3 mm of automobile plates, enamel plates, and galvanized sheets. The six-stand continuous rolling mill mainly rolls tinned sheets with a thickness of 0.15 to 0.5 mm, and the total compression ratio of cold rolling is generally 70 to 90%. The amount of reduction of each frame (or pass) in the rolling is determined according to the pressure, power, and speed of the rolling mill, taking into account factors such as production and quality. Process lubrication Lubricates and cools. Generally, a good cooling performance emulsion is used, and a pure oil lubricant having good lubricating properties, such as a rolled tin plate or palm oil for stainless steel, is used for rolling a thin or hard metal. Annealing The purpose is to eliminate the cold rolling work hardening, to recrystallize the high quality GL galvanized Steel Coil, and to have good plasticity. The annealing method is performed by a hood furnace in a roll annealing and a continuous furnace annealing. Roll annealing is divided into tight roll annealing and loose roll annealing; continuous furnace annealing is divided into vertical continuous furnace annealing and horizontal continuous furnace annealing. Protective gas is generally introduced into the furnace. At present, most of the hood furnace annealing is used. Although the treatment cycle is long, the number of furnaces is large, the use is flexible, and the investment is saved. The continuous furnace annealing yield is large, and the horizontal continuous furnace annealing is only used to treat extraordinary steel with low output, such as decarburization annealing of silicon steel. Smooth The purpose is to avoid plastic instability of the steel coil after annealing and to improve the quality (flatness and surface condition) of the steel sheet. The temper mill has a single-stand reversible type and a double-stand type, and the flat compression ratio is 0.5 to 4%. The double-stand temper rolling mill has high efficiency and large compression ratio, and can also be used for secondary cold rolling at the same time to further thin steel sheets; if it is combined with a five-stand continuous rolling mill, it can produce coils of 0.10-0.15 mm. | ||
| add to favorites | Select High Quality Color Steel Sheet | Cars |
| First, color steel substrate thickness The high-quality color corrugated steel sheet is composed of substrate and color peritoneum or lamella. We must first consider the thickness of the substrate and peritoneal coating. The better color steel substrate is 0.02~0.05mm, the thickness of lamination or coating is usually only 0.15mm. The thickness of the substrate is important because it can affect the service life of colored steel sheets. Some color steel plate manufacturers often cut corners on the substrate and color steel coating or laminating. They reduce the thickness of the substrate, but increase the thickness of the peritoneum, reduce the production cost of color steel sheet, greatly reduce the service life of color steel sheet Second, the outer edge of the color steel sheet When you get a color steel sheet, first observe the color steel sheet cross-section exposed whether the steel sheet is fine crystallization, is gray, black and impurities. If the cut surface crystal and fine, excellent quality. Third, the price of color steel sheet You get what you pay for. When we compare the quality of color steel sheet, high-quality color coated corrugated roof board price is one thing, but do not pay too much attention to the price. If the price of color steel plate is much lower than other steel sheets, then we must pay attention to. Four, color steel quality certificate Does the relevant department have testing standards? If possible, please try to color steel sheet manufacturers on site. Look at the environment of the company, whether normal. Ask about the company's reputation in the market. Fifth, listen to the voice If the fingers or hard objects hit color steel sheet, if the color steel sheet material is poor, the metal sound is not obvious. The louder the metal, the better the color. Color steel sheet is louder, more relaxed. | ||

| add to favorites | How to Store Galvalumed Steel Plate | Cars |
| As one of the commonly used metal materials, the galvalumed steel plate is mainly used in construction, workshop, machine production, and other aspects. At the present stage, the standards stipulate various indicators and quality requirements of aluminum and zinc plated plate, including the chemical composition, its external size, product quality, product internal structure, and its performance structure contained in the aluminum-zinc plate. Although low cost Galvalumed steel plate is strong and precise, but we still need to pay attention to the maintenance in use, in order to extend its service life. If you buy a large amount of one time, after receiving the galvalume steel plate, it is impossible to immediately use up all. The vast majority of aluminum zinc plates need to be stored in the warehouse. When you choose a place or warehouse to store aluminum and zinc plates, you should try to choose a place with a clean environment, ventilation, and unobstructed drainage. Keep away from places that may produce harmful gases or dust. However, it is better to clean up the weeds around the site as well. Because there are plants, the surrounding humidity is relatively large, galvalume steel for a long time in this environment is easy to rust surface. In piling up galvalume steel plate is also a principle, is in stacking solid and ensure the safety of solid conditions, it is best to do according to the galvalume steel plate varieties and specifications placed. If other materials need to be piled up in the workshop or the site, please be sure to place them separately. | ||
| add to favorites | Four Characteristics of PPGI corrugated roofing sheet | Cars |
| PPGI corrugated roofing sheet has the following four characteristics: 1. Fireproofing: The so-called fireproofing of PPGI corrugated roofing sheet for sale refers to two aspects a. As for the fire resistance of the coating, there is no corresponding standard in the current national standard, so other methods are used. Because the color plate has been cured at high temperature, the high-temperature resistance is better than self-drying. b. There are many factors affecting the fire resistance of the structure, such as the strength, thickness of the steel plate and the shape of the profiled plate. The strength of the steel plate is stipulated in the ASTM A792 standard as high-temperature steel (HTS), yield strength 275-380 MPa and tensile strength 360-460 MPa. 2. The corrosion resistance of PPGI corrugated roofing sheets. Generally, PPGI corrugated roofing panels for buildings have strong corrosion resistance and weatherability under the protection of both base plate coating and coating, which makes the life of ordinary paints more than ten times. Seismic resistance, because the color-coated steel plate has greater strength, lighter weight than brick-concrete structure, has strong seismic resistance. 3. The PPGI corrugated roofing sheet has good bending and rolling formability and good processability. 4. The color coated board has beautiful appearance, strong decoration, and observability. | ||
| add to favorites | Color Steel Coil Production Process | Cars - Economy cars |
| After China high quality prepainted color galvanized coil coating process is completed, the tension is transferred to the outlet section after being supplied by the tensioner. The storage unit is empty during the normal operation of the production line. When the outlet section stops and discharges, the storage unit continues to be coated from the roller. The coils that run through the process section are stored again. After the next color steel coil is started to be taken up, the exit section speeds up and the loop is pulled out. The outlet storage unit passes through two deflection rollers, and the tensioner maintains the proper tension in the storage unit, and provides the post tension for the winding. The coil plate reaches the shearing machine through the pallet, the idler and the pallet pin feeder. At the place where the coiled plate is cut, the steering roller enters the winder to wind up. Between the winder and the pinch machine is a photoelectric edge control device, the sensor can measure the edge of the prepainted color galvanized coil, that is, send a signal to the winder to make the chute follow, to ensure the edge winding of the color steel coil. When the winder reaches the required diameter, the winder stops, cuts the coil, raises the trolley, holds the coil, and the main shaft of the winder is shrunk. The feeding trolley carries out the color steel coil for bundling. And weighing. The head of the next color steel coil is fed into the winder, and the winder is accelerated until China prepainted color galvanized coil in the stocker is finished. This way the outlet section runs at the same speed as the overall production line. | ||
| add to favorites | Precautions for Choosing A Color Coated Sheet | Cars |
| In order to further improve the corrosion resistance of China Galvanized Steel Roofing Sheet for sale, the surface zinc layer is not directly in contact with the air, and the surface coloring property is increased, and painting is required. That is to say, depending on the application, it is necessary to select a suitable substrate and coating, and adopt appropriate painting methods to produce a color-coated roofing sheet that meets the requirements. In order to have good adhesion to the surface of the coating and the galvanized sheet, the galvanized surface needs to be chemically treated. First, clean the oil and dirt attached to the surface of the galvanized sheet, otherwise, it will affect the adhesion of the coating, so it needs to be decreased and cleaned. The chemical conversion treatment is then carried out, usually by forming a layer of composite oxide on the galvanized surface or by phosphate treatment. The former has good paint film adhesion, while the latter has good corrosion resistance. After the chemical conversion treatment, it is sufficiently dried to be painted without moisture. Under normal circumstances, low cost color-coated corrugated roofing sheet generally has two aspects to pay attention to. 1. Selection of substrate (substrate strength, galvanizing amount and surface finishing, etc.) 2. The choice of paint. How to choose color-coated plates is an important problem in use, resulting in waste, that is, material properties cannot meet the requirements of use. Hot-dip steel plates have many uses in construction. | ||
| add to favorites | Benefits of Cleaning GI Steel Coils | Cars |
| Buyers should be aware of the correct use of high-quality GI coils when using them, as only knowing the benefits of cleaning galvanized steel coils can cause any problems during use. How do GI steel coil with spangles manufacturer share the correct operation? In the process of cleaning the GI coil, in order to ensure the stability of the rolling process in the future, the use of the emulsion can reduce the rolling force and ensure the surface quality of the galvanized steel. When an emulsion is used, the addition of the additive and the emulsion together can improve the performance such that the lubricant forms a reticulated adsorption film on the metal surface to improve the quality of the GI steel coil with spangles. The surface quality gives the coil a toughness and compressive strength for future use. Since the adsorption of polar molecules and metal surfaces in the emulsion is large, the additive, on the one hand, improves the rolling properties of the emulsion and ensures the stability of the rolling. On the other hand, the oily components in the hydraulic system of the rolling mill, polar molecules and emulsions in additives such as fine iron powder and oil leakage are stably present on the uneven surface of the GI steel coil with spangles by strong polarity. | ||

| Mastering the scientific installation and maintenance methods can effectively extend the service life of color steel plates for more than 10 years, which not only reduces the use cost of the plant but also maintains a good corporate image. China color corrugated steel sheet manufacturers tell you that the specific four aspects should be used: 1. During the processing and installation of color coils, it is found that the coating is damaged (when it is not rusted), and it should be repaired in time. When the paint is replenished, the same color steel coil refinishes paint can be brushed or sprayed, and the repair paint is matched to prevent rust and corrosion caused by the damage of the coating. After the installation is completed, use a dry rag or another soft tool to clean off the iron filings attached to the surface of the color steel plate by the cutting saw and the electric drill to prevent the occurrence of floating rust. 2. Roof tile, China color corrugated steel sheet manufacturers recommend that users check and maintain once a year. Iron filings, copper scraps, industrial dust, metal particles, water accumulation, and other long-term residual roof tiles, easy to accelerate coating corrosion, if found, the user should promptly organize cleaning, cleaning, removal. If the coating is found to have rust spots, it needs to be sanded. Before the touch-up, you must remove the grinding powder and rust spots. Apply anti-rust primer in a clean and dry state, and then apply a special repair finish for steel coil of a certain thickness. 3. In order to prevent long-term residence of roof corrosion, the user can use the cleaning method to maintain the roof panel. In the seaside and industrially contaminated areas, the maintenance period should be shortened. Maintenance by cleaning method, do not use decontamination powder or industrial detergent (which will damage the coating) and can be determined after a small area experiments with household detergent. 4. After the color corrugated steel sheet is used for a certain period of time, due to factors such as sunshine, rain, oxidation, etc., the coating is inevitably degraded by powdering. In order to maintain the structural life of the building, repainting and repainting is a good choice. When the powdered surface of the color coated board turns gray, it is the best time for recoating. Recoating should be carried out as much as possible during the drying period with less moisture. Well, the above are some tips for the scientific installation and maintenance of color steel roofing sheet. Have you mastered it? | ||

| Color steel coils are now used in many building materials. This material plays an important role in many aspects of the construction site. In fact, the development of color steel coils is not particularly smooth, except for prepainted color galvanized coil price. It has many advantages, and its shortcomings have many problems. Now let's take a look at the advantages and disadvantages of color steel coils. In construction sites, the lighter the material, the easier it is to install, and the color steel coil is like this. It is light in weight and much lighter than brick walls. Although its lightweight, it does not mean that its performance is poor, it has a good thermal insulation function, and its thermal conductivity is still very good. If we need color steel coils to take on the weight of some coils, then its strength is also very good, able to resist bending, but also resist pressure. If the high quality prepainted galvanized steel coil is installed on the outer wall, its color is very beautiful and bright. At this time, it is not necessary to use other materials to decorate the material, and it is also very convenient and flexible during the installation process. The entire construction time is greatly reduced. Of course, color steel coils also have disadvantages, for example, its maintenance costs are relatively high. If the color is reduced after a long time, it needs to be maintained. Although it does not matter if it is not complementary to it, it has a great influence on the appearance. When the color steel coil is in contact with the outside world for a long time, it will still rust. At this time, it will affect the use, so that the ability to resist the basic snow will decrease. The above is the color steel coil. The advantages and disadvantages were introduced. | ||
| add to favorites | How to make multiple color steel coils | Cars |
| The use of hot sale aluminum zinc steel coil cannot be one, so the connection becomes a problem. So how do you know how to bridge multiple color steel coils? If there is a bad connection, there will be problems. The basic methods of lap jointing are lashing, welding, mechanical connection, and the like. Color galvanized steel coil installations are often fixed with rivets or bolts. For the overlapping of the lateral and end of the color steel coil, it is an important step to install the color steel coil, and the lapping effect affects the later installation. Today, Xiaobian will share with you how to make multiple color steel coils: First, use a pair of jaw clamps to clamp the overlapped steel coils. When the high quality GL Galvanized Steel Coil is in the longitudinal direction, the end portion, especially the upper-end portion, needs to be clamped with the gusset portion, so that the end of the steel coil is placed in position, and the overlap at one end is also in the correct position, thereby fixing the steel. Roll, the clamp should always clamp the steel coil in the longitudinal direction during the fixing process. Note that when installing each steel coil, it should be placed on the previous steel coil accurately and clamped with the previous steel coil until both ends of the steel coil are fixed. Each steel coil must be completely secured before the next steel coil is installed. The fixing must start at the center of the GL galvanized steel coil and then extend to both sides, finally fixing the overlapping edge of the coil. | ||
