Steel Structure: Welded Steel Grating
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.
Materials: mild steel, stainless steel 304 or 316.
Surface treatment: galvanizing, bitumen dipped, painted, untreated.
Top surface: plain, flattened, raised.
It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost-saving openness maximizes the circulation of air, light, heat, water, and sound, while promoting cleanliness. And, where insurance codes permit, additional sprinklers can often be eliminated. Standard panels are available in widths of 2', 3' or 4'.
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 crossbars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The crossbars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.
