Hot Dip Galvanized Steel Driveway Grating For Drain Cover 30*3mm
Description of Steel Grating Walkway
The steel walkway grating is a perfect combination of steel bar grating and checkered plate, featuring beautiful appearance and high solidity. When it comes to the manufacture of compound steel bar grating, 3G323/40/100, 3G253/30/100 and 3G323/40/100 steel bar grating are most often used as the base plate. Then, weld 3mm thick checkered plate upon the steel grating panel. The checker plate thickness also can be 4mm, 5mm. After proper polishing and hot dipped galvanized surface treatment, a good condition compound steel bar grating is produced. In consideration of different working conditions, the dimensions and materials of steel grating and checkered plate can be customized. We can produce carbon steel, stainless steel compound steel grating.
(1) Structure: Welding with flat steel and cross/round bars with certain distances.
(2) Features: High strength, light structure, high bearing.
(3) Surface: The hot dipped zinc coating gives the product excellent anti-corrosion
1.Plain type:
One of the most wiely used gratings, available for flooring, sidewalk, dranage pit cover, stair tread, etc
2.Serrated type:
Better Non-skid property & safety compared with plain grating
3.I-shape type
Lighter, more economical and practical comparing with plain grating
