Title Distinguish GL galvanized steel coils and galvanized plate
Description 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.
