Building Materials Galvanized steel grating weight per square meter
Steel Grating /grate floor made by welding with flat steel and cross/round bars with certain distances. Our Steel Grating enjoy the feature of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion.
Carbon Steel Bar Grating is an ideal option when your project requires a strong material that will not be exposed to an expressly corrosive environment. we suppliy both smooth and serrated bar grating. Bar gating is available in galvanized, painted black, plain steel, light duty, and heavy duty.

use of steel grating
High strength and high bearing capacity:
- Non-slip, anti-corrosion, not easy to deform.
- High safety performance.
- Do not accumulate rain, snow and dust.
- Simple and beautiful appearance.
- Easy to install and remove to extend the lifespan.
- Applications of serrated welded steel grating
- Serrated welded steel grating is widely used as platforms, stair treads, walkaways and floors in industrial, civil and commercial buildings.
Advantage:
- No corrosion traps around joints
- High strength to weight ratio
- Allows shaping without loss of strength
- Available plain or serrated
- Allows passage of heat, light, water and ice.
The applications of steel grating:
- -Fencings for car-parks, buildings and roads; drainage trench covers and drainage pit covers for highways;
- -Flooring in various bridges such as railway bridge sidewalks, over-bridges across the street;
- -Rotation ways, channels, and platforms for pump rooms and engine rooms in various ships;
- -Platforms for oil extraction sites, car washing sites and air towers;
