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.
standard welded steel bar grating 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'.
standard 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.
Main products include steel grating, stair treads & industrial ladder, trench grating cover, handrails, grating clips, cable tray , which are used in Petrochemical Industry, Oil Fields, Boiling Platform, Seaport and Vessel Construction, Power Plant, Industrial Floor Platform, Municipal Engineering and so on. 70% products are regularly exported into USA, Latin America, Australia, Kuwait, UK, France, Japan and Southeast.
