Steel Grating
<p>Steel grating is a high-strength structural plate formed by pressure-welding bearing bars and cross bars together under high pressure, commonly manufactured with carbon steel, galvanized steel or stainless steel as raw materials. It is a widely used industrial flooring and drainage product, famous for its lightweight but high load-bearing capacity, outstanding ventilation and anti-slip performance. After producti…
About this product
Product information from the supplier.
Compared with solid steel plates, steel grating greatly reduces self-weight while retaining excellent mechanical strength. The hollow grid structure provides good drainage, dust dissipation and ventilation effect, avoiding water accumulation, sludge buildup and snow piling on the surface. Serrated anti-slip steel grating is specially designed for slippery scenarios to prevent workers from slipping during walking. Custom shapes including circular, curved, cut-out and special-size gratings can be processed to meet engineering layout demands. This product is extensively applied in factory walkways, platform flooring, trench drainage covers, stair treads, municipal drainage projects, chemical plants, sewage treatment stations, offshore platforms, parking lot drainage and municipal road construction.
Steel Grating Advantages
High strength & lightweight structure, stable bearing performance under concentrated load.
Hot-dip galvanized coating delivers excellent anti-corrosion, anti-rust performance for 10–20 years outdoors.
Open grid design ensures fast drainage, anti-clogging and easy cleaning.
Serrated surface option greatly improves anti-slip property for wet and oily working conditions.
Easy cutting, installation and later maintenance, saving overall project cost.
Customized size, shape and material (304/316 stainless steel for chemical corrosive environment) are available for bulk orders.
