WELDED STEEL BAR GRATING
11W2 11/16" CENTER TO CENTER OF BEARING BARS

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.

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.

U = safe uniform load, psf

Material: ASTM A-569 standard

C = safe concentrated load, pfw

Deflection: Spans and loads to the right of the bold line exceed 1/4"
deflection for uniform load of 100 psf which provides safe pedestrian
comfort. These can be exceeded for other types of loads with engineer’s
approval.

D = deflection, inches

E = modulus of elasticity, 29,000,000 psi

F = fiber stress, 18,000 psi

Serrated Bars: For serrated grating, the depth of grating required for
a specified load is 1/4" deeper than that shown in the table.

General: Loads and deflections are theoretical and based on static
loading.

Click on desired panel size: 2' x 20', 3' x 20', 3' x 24'
