Welded grating is manufactured using an automated process combining hydraulic pressure with a powerful electric welding current which electro-forges the bearing bars and the cross bars to form a single rigid panel. 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.
