Product Description

Factory Wholesale Hot DIP Galvanized Drainage Steel Grating

Steel grating, also known as steel grid plate or steel grille, is constructed by arranging flat steel bars at specific intervals and welding them with cross bars (twisted square steel, square steel, round steel, or flat steel) to form a square grid pattern. This durable product is primarily used for drainage covers, structural platforms, and stair treads.

The cross bars are typically made of twisted square steel (twist steel). Constructed from carbon steel with hot-dip galvanization for oxidation resistance, these gratings can also be manufactured in stainless steel. They offer excellent ventilation, lighting, heat dissipation, anti-slip properties, and explosion resistance.
