Plain/Flat Steel Grating
General Introducion
Plain steel grating, also called flat or smooth surface grating, is a type of grating made of plain steel bars. The smooth surface contrast with serrated steel grating, which has a serrated surface. plain steel grating is the most widely used grating type, which is used in almost all of the applications.
Plain steel grating can be made of carbon steel bar, aluminum steel bars and stainless steel bars. Cross bars of plain steel grating can be crimped bars, which are known as riveted steel gratings, flat square bars which are the press-locked gratings. The round bars is welded to the bearing bar is welded steel grating and the bars are placed into the pre-holes on the bearing bars to form the swage-locked grating.
· Materials: low carbon steel, stainless steel.
· Surface treatment: galvanized, powder coating, painted color.
· Standard Mesh size: 30*50mm, 30*100mm, 40*50mm, 40*100mm etc

Applications of plain/flat steel grating
· Serrated steel grating features outstanding slip resistance, it is widely used in the environments filled with water, oil and other elements may cause slipping.
· It is widely used as stair tread grating to secure pedestrians safely go up and down.
· The serrated steel grating is widely used as platform walkway grating in pedestrian street, balcony and factories for anti-slip application.
· The serrated steel grating can be installed on the drainage and trench as drainage trench cover to drain water and keep ground dry.
Packaging:
Strap packing: Generally used for neat press locked steel grating.
Pallet packing: Generally for the press-locked steel grating which need to export and load in container.
Screw rod fixation: Use four screw rods through the mesh and fixed with screws.
