Steel Grating Overview

Steel grating, also known as bar grating, features a square grid pattern composed of flat bearing bars and cross round bars. This versatile product is primarily used as gutter covers, steel structure platform walkways, and stair treads for steel ladders.

Manufactured typically from carbon steel with hot-dip galvanized surface treatment to prevent oxidation, steel grating is also available in stainless steel and aluminum variants to suit various applications and environmental conditions.
