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 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.

When order the welded steel grating, first specify the type of grating from the table below. In the instance of standard welded grating, the "W" indicates the assembly of the grating shall be Welded construction, the "19" indicates that the bearing bars shall be 19/16's (1-3/16) inches on center, and the "4" indicates that the cross bars shall be spaced at 4 inches on center. Following selection of the type of grating, consult the Steel Bar Grating Load Table to select the appropriate bearing bar size for the loads and spans to be serviced. Proper designation for standard welded grating with 1" × 3/16" bearing bars is indicated W-19-4 1" × 3/16".
