Serrated steel grating is a type of steel grating made by serrulating flat steel raw materials and then welding the flat steel to twisted round steel bars. Unlike ordinary steel grating, serrated steel grating requires the flat steel's stress direction, the distance between flat steel bars, and the distance between twisted round steel bars to be processed according to customer-provided drawings. It is a type of anti-slip steel grating product.
The raw material for serrated steel grating, flat steel, includes: 202, 203, 253, 303, 304, 305, 323, 324, 325, 403, 404, 405, 503, 504, and 505 low-carbon Q235 flat steel.
Serrated steel grating generally uses welding methods such as twisted round steel welding, flat steel butt welding, center rod welding, and semi-insertion welding. Twisted round steel bars are generally available in two sizes: 6.0mm and 8.0mm.
Common Specifications and Applications of Serrated Steel Grating:
1. A 3.0cm spacing between flat bars is the most commonly purchased specification, providing good resistance to impacts from pits. Applications: Power plants, sewage treatment plants, fertilizer plants, chemical plants, pedestrian overpasses, drainage ditches, and other environments with prolonged water accumulation, oil stains, or dampness, providing excellent anti-slip properties.
2. A 4.0cm spacing between flat bars is the economical basic type of serrated steel grating, conforming to international standards for serrated steel grating walkways, stair platforms, and steps. Ideal for use in work applications with narrow spans between steel beams, it is an ideal anti-slip steel grating product. Even in terms of load-bearing capacity, as long as it does not exceed standards, it can be used for cargo transportation without collapse. Applications: Warehouse shelves, mezzanine panels, trestle bridges, protective gratings, etc.
3. A 5.0cm spacing between flat steel bars is commonly used in the mining industry. This type of steel grating addresses the problem of ore spillage on the ground. It typically uses a 5.0x6.0cm spacing to allow most of the ore to fall while ensuring a clean and safe surface. This type of steel grating is often used above broken grating surfaces, in walkways on conveyor lines, in ball mills, and in operating stations.
