Customer Reviews
Yes we have received the reinforcing mesh and we are pretty happy with the quality. Many thanks! Chris

—— Chris Johnson

I have been ordering powder coated T 316 fly screen mesh from Qijie; unlike others, they never cut orders and always supply quality material to me.

—— Michael Jr. Venida

I had very bad purchasing experience with the previous supplier, for they always postpone shipment time. To my excitement, Qijie is always punctual.

Welded Industrial Steel Grating , Mild Steel Grating Plain Bearing Bar​
 
Serrated welded steel grating is made of low carbon steel and stainless steel. With the features of high strength, high bearing capacity, non-slip, anti-corrosion, high safety performance, do not accumulate rain, snow and dust and long lifespan, it is widely used as platforms, stair treads, walkaway and floors in industrial, civil and commercial buildings.
 
Welded steel grating, is the most popular and common type of steel grating. As you can see from the name, the technology is pressure welded. First we put the bearing bar/flat bar into the mould, the cross bar in the machine, then 2 cross bars will come out, by high temperature the cross bars will be welded into the bearing bars.See below pic for reference.
 
Galvanized steel grating, is steel grating being hot dip galvanized.Steel grating, is also named as metal bar grating, it is made by welding flat steel and bars with certain distances. Metal bar grating can be defined as a series of metal bars positioned vertically, placed an equal distance apart and joined by cross bars or twisted rods members to form a rectangular pattern. Typically manufactured from mild carbon steel, The products are used broadly across many industrial and commercial applications. Common uses range from walkways, platforms, trench covers, fences, and other properties. We supply standard panels and customized gratings as per clients requirements. Hot dipped zinc coating gives protection for steel grating, it can prevent steel grating from rust.
