STANDARD WELDED STEEL BAR GRATING

In 19W4 & 19W2, 1 3/16" 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.

Aluminum Bar Grating

Corrosion resistant, non-sparking, rustproof aluminum grating has many applications due to its light weight and high strength. It is ideally suited for use in corrosive environments and finds wide applications as walkways and platforms in sewage treatment plants, refineries, chemical processing plants, pumping and compressor stations, and aboard ships and barges.
Because it does not rust, it is commonly used in breweries, bottling plants, and food preparation and storage facilities. In munition plants, other volatile industries and areas, its non- sparking properties make it a must for safety. It is available in standard or
anodized finishes.  
   
     
Press-Locked Rectangular Bar Grating is constructed with the two close-tolerance slotted bars
bonded together (positioned every 2" or 4") using tremendous hydraulic pressure. Permanent locking is achieved by forcing the deep cross bar into the bearing bar. Both the cross bars and the bearing bars provide walking surfaces in the press-locked design.   
 
  
Rectangular bar grating in either the swage-locked or press-locked styles is your best choice when lateral stiffness is required. The rectangular bar is also available in a serrated surface for additional safety.
