1.Welded Steel Grating

     When selecting a bar grating product, consider Welded Steel Grating first. Usually our most economical products, they provide a comfortable walking surface with nearly 80 percent open area. This, combined with the positive welded cross bar/bearing bar intersection, make these products our most popular. Manufactured from ASTM A-1011 carbon steel, welded gratings are recommended for nearly all industrial floorhen selecting a bar grating product, consider Welded Steel Grating first.

2.Swaged Aluminum Grating

     Aluminum grating products are light in weight, resistant to atmospheric corrosion, non-sparking and offer an attractive appearance. These characteristics make aluminum grating especially suitable for water and sewage treatment facilities, marine environments, food processing and petro-chemical installations.

3.Pressure Locked Grating

    Grating Pacific offers two distinct types of Pressure Locked Gratings which are identified by their method of assembly. Manufactured without the introduction of heat or riveting, these gratings provide a finished product with attractive architectural lines. This pleasing appearance makes Pressure Locked Gratings ideal candidates for architectural and ornamental applications such as grilles, screens and fences. Additionally, pressure locked methods of manufacturing allow for the production of close mesh gratings with minimal open area. 

4.Stainless Steel Grating

     When considering grating for food processing applications,shipboard use, or highly corrosive environments, Stainless Steel Grating is often the most cost effective product.Commonly manufactured in 300 series alloys, stainless steel gratings are assembled by welding or pressure locking to suit the specific needs of each application.To specify Stainless Steel Grating, the type of grating is indicated by designating one of the three profiles shown combined with the bearing bar/cross bar spacing illustrated in the table below.
