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.Manufactured from 6061 and 6063 alloys, the most popular and economical method of assembly for aluminum gratings is pressure locking by the swaging process. This versatile manufacturing system allows us to offer three distinct profiles: Standard Rectangular Bar, Flush-Top Rectangular Bar and I-bar. Each profile is illustrated below.
To specify Grating Pacific Swaged Aluminum Grating, the type of grating is indicated by designating one of the three profiles shown combined with the bearing bar/cross bar spacings illustrated in the table below. Following selection of the type of grating, consult the Aluminum Grating Load Table to select the appropriate bearing bar size for the loads and spans to be served.
BAR PROFILE "AI"
Lighter, extruded I-beams with a standard skid resistant, fluted surface have essentially the same load carrying capacity as rectangular bar products of equal depth.RECTANGULAR BAR PROFILE "A"
Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically swaged to lock the bars in place. Most effective for the manufacture of aluminum, stainless, and close mesh gratings.
FLUSH TOP PROFILE "AF"
Similar to Profile "A" except the special extruded cross bar is swaged flush with the top surface of the bearing bars providing a more comfortable walking surface.SAMPLE SPECIFICATIONS FOR STANDARD ALUMINUM GRATING
