Welded belt bridge

Poly-coated welded flat bar is a type of steel strip protected with a polymer coating, offering high resistance to corrosion and wear. It is made from carbon steel with a carbon content of 0.18 to 0.28 percent and has a tensile strength ranging from 400 to 550 megapascals. The width of the poly-coated strip typically ranges from 25 to 150 millimeters, with a thickness between 3 and 8 millimeters. Dimensional tolerances are maintained at ±0.4 millimeters in width and ±0.15 millimeters in thickness. The polymer coating, applied uniformly at a thickness of 50 to 100 microns, enhances surface mechanical properties besides providing protection.

The manufacturing process of the poly-coated welded flat bar includes resistance or laser welding of the steel sheet, followed by polymer coating application through spraying or dipping methods. The surface hardness ranges from 130 to 190 Brinell, with capabilities for cold bending, precise punching, and UV resistance. This product is produced according to international standards such as ASTM A572 and DIN EN 10142, widely used in automotive industries, agricultural equipment manufacturing, and corrosion-resistant structural applications.
