Product Description
Aluminum Steel Grating Aluminum Grating Steel Anti Skids Aluminum Metal Serrated Steel Grating
Steel grating also named bar grating.
The grating is with a square grid in the middle, composed by flat bearing bar and cross roun bar. mainly used as gutter cover, Steel structure platform walkway, steps of steel ladder, etc.
The steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel, aluminum steel.
According to the welding method, it can be divided into: machine forge welding type and handmade manual welding type.
According to surface of the loaded flat steel, it can be divided into: flat type, tooth type and "I" type.
According to its purpose, it can be divided into: trench cover, platform walkway, stair treads.
According to its mateiral, it can be divided into: midl steel, aluminum, stainless steel.
