Flooring Grid Plain Bar Galvanised Steel Grating For Platform
Hot Dip Galvanized Steel Grating- GI Steel Grating
Platform Channel Gratings are made of aluminum or steel alloy bar structure panels with big bar spacing and strong ability of anti-side shocking. Can be supplied with checkered plate shielding, installation connectors and other accessories.
Platform Steel Gratings are new building materials used in construction of power plants, boilers, shipbuilding, petrochemical, chemical and general plant room, municipal construction and other industries. The steel bar grating platform structures enjoy good air and light ventilation, non-slip property, good bearing capacity, easy cleaning and installation.
Platform Gratings are universally used in most general industrial plants as well as commercial buildings, as walkways, platforms, safety barriers, drainage covers and ventilation grates. Welded Steel Bar Grating is the most popular of all grating platform types due to its strength, cost-efficient production and ease of installation.
Welded steel bar grating is resistance welded to create a rugged, one-piece constructed panel. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.
