Description
Galvanized Steel Grating Panels & Stair Treads
Steel grating, also known as bar grating, features a square grid pattern formed by flat bearing bars and cross round bars. These durable panels are primarily used as gutter covers, steel structure platform walkways, and stair treads for steel ladders.
Material Composition
Our steel grating is typically manufactured from carbon steel with hot-dip galvanized surface treatment to prevent oxidation. We also offer stainless steel and aluminum steel options to meet various environmental and application requirements.
