Heavy steel grating refers to steel grating with a flat steel width of more than 50mm and a flat steel thickness of more than 6mm, designed for load-bearing requirements exceeding 10 tons. The crossbars are typically constructed from flat steel or steel bars with diameters of 10mm or 12mm. This specialized grating is engineered for heavy-duty applications and can be manufactured through pressure welding or pressure locking processes. Ideal for airports, highways, industrial platforms, ports and docks, and other demanding environments.
