Metal Building Materials Galvanized Drain Car Park Drainage Steel Grating For Construction

Product Description 

Welded Steel Bar Grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Universally used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.

 
Product Specification&Model

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.
