Description
High-Strength Serrated Stainless Steel Grating for Stairs & Drainage
What Is Steel Grating?

Steel grating is manufactured from high-quality carbon steel or stainless steel. Flat steel bars are arranged crosswise at specific intervals and welded into a grid pattern with square openings. The exterior of steel grating is typically hot-dip galvanized to provide corrosion resistance.

Steel grating offers excellent ventilation, light transmission, anti-slip properties, strong load-bearing capacity, heat dissipation, easy cleaning, and simple installation.
