Aluminum Grating is Corrosion resistant, non-sparking, and rustproof. It 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 munitions plants and other volatile industries and areas, its non-sparking properties make it a must for safety. It is available in standard or anodized finishes. Swage-Locked Rectangular Bar Aluminum Grating uses the swaging process to permanently lock the cross rods (positioned every 2" or 4") to the rectangular bars Swage-Locked I-Bar Aluminum Grating is the most widely used and provides the strength equal to a rectangular bar of the same depth, but at far less weight and cost. The I-bars are permanently locked to the cross rods (positioned every 2" or 4") by a swaging process. Press-Locked Rectangular Aluminum 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.
