The water leakage caused by the material characteristics of the hot sale color-coated corrugated roofing sheet roof leakage. 1. Construction factors a. During the construction process, the corrugated roofing sheet is not protected, and the roof is arbitrarily stepped on, which destroys the flatness of the roof and even the potholes. b. Because the span of the steel structure factory is too large, in many cases, there is a lap joint process in the roof panel. Although the sealant and the rivet are used in the lap joint, the installation is often difficult to reach the design theory standard, resulting in leakage. rain. c. Some color steel gutters are not preserved. Some construction units' gutter anti-corrosion is only brushing anti-rust paint or asphalt paint. After using for a period of time, the gutter is seriously corroded and even rotted and deformed. 2. Use factors a. The house increases the load at will during use, causing the color steel plate to deform. In particular, the load is arbitrarily increased on the roof rafter, and the rafter is deformed, resulting in water in the house area. b.

GI steel coil with spangles in stock is a wide range of applications, which can be seen in the fields of enterprises, home appliances, construction, and electromechanical. The GI steel coil is divided into two types: hot-dip galvanized steel sheet and electro-galvanized steel. Then, the small professionals of HENGZE will tell you about the four factors that cause the GI steel coil with spangles to crack. 1. Annealing temperature The annealing temperature is an important process parameter in the galvanizing process, and the annealing temperature has a great influence on the yield strength of the product. When the annealing temperature is low, the annealing is insufficient, the crystal grains are fine, the strength is high, and the elongation is low. When the annealing temperature is too high, the grain is abnormally coarse, the yield strength is lowered, and the tensile strength is further reduced. The product is in the customer. Direct fracture during press forming and stretching 2. Inclusion and other defect control Defects such as inclusions and foreign matter intrusion are very unfavorable for press forming of stamped products, and since the local elongation of the inclusions is insufficient, punching and tensile cracking are likely to occur.

The purpose of the bending test for the surface coating of high quality Galvalume Corrugated Roofing Sheet: The purpose of the bend test of the coating is to detect the flexibility of the film. It is one of the important items to evaluate the coating logistics performance of high quality Galvalumed steel sheet by measuring the crack resistance or peeling resistance of the coating when the sample is bent. Many of the coated substrates have certain deformability, so the coating is also required to have corresponding flexibility. After curing, the bending test of the coating is to bend the sample 180° around itself and then along the curved surface. Apply a scotch tape, tape the tape while removing the air bubbles, and then quickly peel off the tape in the direction of 60° along the curved surface. Visually observe whether the curved surface of the coating is cracked or peeled off, and make sure that the coating does not produce. The lowest thickness of the sample that is cracked or peeled off. High-quality Galvalume Corrugated Roofing Sheets are familiar to everyone. We all know that galvanized sheet steel is cold-rolled or hot-rolled, and long and narrow strips are plated with different layers of raw materials called (zinc, aluminum). Aluminized zinc has the advantages of uniform plating, strong adhesion, and long service life. The hot-dip aluminum-zinc plate steel substrate and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant structure of a zinc-iron alloy layer.

Four major effects of surface finishing of the galvanized coil 1. Improve the surface flatness of the hot sale galvanized steel coil. After finishing, the flatness of the galvanized coil is improved, and the wave shape of the galvanized coil is partially eliminated, and the slag particles or other uneven spots on the surface can be flattened to make the surface smooth and flat. 2. Adjust the roughness of the surface of the hot sale galvanized steel coil. By controlling the roughness of the surface of the work roll of the finishing machine, the original uneven roughness of the surface of the galvanized coil can be unified to a certain extent. This improves the paintability of the product and the lubricity during processing. 3. Improve the surface color of the galvanized coil. For zinc flower and zinc-free flower products, the galvanized coil 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 plates can make the zinc flower bumps and different glossiness of the large zinc flower crystallize and unify, which makes the zinc flower blurred and unfavorable. Cover the zinc flower when painting. 4. Improve the processing performance of hot sale galvanized steel coil. By finishing, the yielding platform of the galvanized coil can be eliminated or become inconspicuous, and the occurrence of metal slip lines in subsequent processing can be prevented.

Now the steel industry is developing better and better. The former iron products are easy to rust and easy to corrode and not durable. The cold rolled steel coil factory in stock is also slowly replacing the original iron products. The cold rolled coils have good surface quality, high smoothness and are not easily oxidized. Business welcome. Moreover, many consumers are entangled in the purchase process. What is the difference between cold rolled coil and cold rolled strip? Let's talk about their differences today: Cold rolled coils are often called cold rolled coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard rolls are increased, and the toughness index is lowered. Therefore, the punching performance is deteriorated only for the parts that are simply deformed. The cold-rolled steel sheet is processed from a hot-rolled sheet at a normal temperature. Although the steel sheet is heated during the processing because of rolling, it is called cold rolling. Since the cold rolling of the hot rolling through the continuous cold deformation is relatively poor in mechanical properties, the hardness is too high. It must be annealed to restore its mechanical properties. The unrolled hard rolled coil is usually used for products that do not require bending. The cold-rolled coil is produced by rolling hot-rolled coils at room temperature below the recrystallization temperature, including plates and coils. Many domestic steel mills such as Baosteel, Wuhan Iron and Steel, and Anshan Iron and Steel can produce. The steel plate, also called the steel plate, is also called the steel plate, which is called the steel plate or the flat plate. Cold rolled coils are used in a wide variety of applications such as automotive manufacturing, electrical products, rolling stock, aviation, precision instruments, and food cans. Cold-rolled steel sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet. Also known as cold-rolled coil, cold plate is sometimes mistakenly written as cold-rolled sheet.

1. After all the high quality Galvalumed steel sheet are placed on the roof or several independent units are hoisted, the seams are adjusted. The seams are adjusted to be smooth and straight, and the width of the joints is as uniform as possible. Generally, the width is 20-30mm. 2. Welding: After the board joint adjustment is completed, the board and structure are welded. Each plate is welded at least 3 points, the welding length is 6cm, the thickness is 4mm, and the welding slag is removed after welding. If it is not guaranteed to weld more than three points, the plates are connected by steel bars. 3. Caulking: After welding, a polystyrene rod (polyethylene foam rod) with a diameter of 1.5 times is used to seal the bottom of the gap from top to bottom. 4. Caulking: Use 1:6 cement perlite mortar to fill the gap and compact it. The core material is dry and thick. It is better to use steel bars or trowels when filling the joints. 5. When the core material has a certain strength, brush a layer of polymer mortar in the gap, and the thickness is 1mm. The above is the whole process of installation and construction.

The corrosion resistance of the passenger car body is affected by factors such as the environment, materials used, structural design, manufacturing process and maintenance. Among them, the body electrophoretic coating anti-corrosion in the manufacturing process has been widely concerned in domestic OEMs, and the simultaneous process analysis has been carried out, but the utilization rate of China high quality rolled hard roll steel coil materials is still relatively lagging due to cost constraints. It is very necessary to establish a set of effective body galvanized sheet design database for the anti-corrosion process of the passenger car body, so as to formulate the specification of the galvanized sheet of the passenger car body to effectively improve the anti-corrosion performance of the product and optimize the anti-corrosion design cost. A.Corrosion process of galvanized sheet Generally, the corrosion process of Galvanized Steel Coil made in China is divided into four stages, namely: the corrosion stage of the plating layer; the sacrificial corrosion prevention stage of the substrate after the partial disappearance of the plating layer; the stage of corrosion inhibition of the substrate by the galvanizing corrosion product; the substrate is uncoated The corrosion phase of the time. B.Galvanized layer corrosion resistance factor The thickness of the galvanized layer is one of the most important factors determining the corrosion resistance of the steel substrate. According to the Swedish anti-corrosion study, the anti-corrosion performance of the galvanized layer is the most reasonable when it is 7-10 mm thick, and there are also domestic related researches, the thickness of the coating. It has better resistance to under-film corrosion when it is more than 60g/m2. At the same time, the corrosion resistance of Galvanized Steel Coil made in China in actual use depends not only on the galvanized steel sheet itself, but also on the processing state and the use environment of the galvanized steel sheet. These three factors can also become corrosion triangles of the galvanized sheet.
