Product Description


Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.

1. At each intersection of load flat steel and cross bar, it should be fixed by welding, riveting or pressing lock.

2. Pressure resistance welding or arc welding are preferred in the welding of steel grille.

3. The pressure lock of the steel grille can be fixed by pressing the cross bar into the loaded flat steel by a press.

4. Steel grilles should be processed into various shapes according to the needs of users.

5. The spacing of the load flat steel and the spacing of the cross bar can be determined by the supplier and the demander according to the design requirements. As an industrial platform, it is suggested that the spacing of load flat steel should not be greater than 40 mm and the spacing of cross bar should not be greater than 165 mm.
