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;

Type of Steel Grating

Comparison of Feature:

Plain:One of the most widely used grating, available for flooring, sidewalk, dranage pit cover, stair tread, etc.

Serrated:Better non-skid property & safety comparing to plain grating

I-shape:Lighter, more economical and practical comparing to plain grating.

Manufacturing Tolerance of the Gratings

There is no maximum allowable tolerance for every dimension given here.

Steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and easy installation,

Universally used in most general industrial plants as well as commercial buildings,

It has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.

Standard welded steel bar grating is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring, more than that
