hot dipped galvanized press welded 2mm steel grating for drainage channel​

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.
