Aluminum grating are typically shipped "mill finish" with no additional treatment. For architectural applications or highly corrosive environments, supplemental anodizing, chemical cleaning, or powder coat finishes are available.
• Mill finish (no finish)
• Anodized (clear, bronze, other)
• Powder coating
Aluminum grating is manufactured from ASTM B221, 6063, or 6061 alloy, aluminum grating is available in four distinct products: type "SG" Swaged Rectangular Bar, type "SGI" Swaged "I"-bar, type "SGF" Swaged Flush-Top, and type "ADT" Dovetail Pressure Locked. All four products are available with bearing bar spacing ranging from 19/16" (1-3/16") to 7/16" on center and with cross bars at either 4" or 2" on center.
SG aluminum grating is made of aluminum plates and cross bars. It is manufactured by inserting cross bars into pre-punched holes in the bearing bar. The cross bars are then swaged forming a positive mechanical connection. Bearing bars are available with standard plain or optional serrated or Algrip surfaces. The cross bars are fully locked within the bearing bar, slightly below the top surface.
SGI aluminum grating is made of I style aluminum plates and cross bars. Advantages include reduced weight per square foot and the striated flanges of the "I"-bar provide enhanced skid resistance without the added cost of serration.
SGF Swaged aluminum grating is flush-Top aluminum grating. Manufactured with a unique, extruded cross bar that is flush with the top surface of the bearing bars, type "SGF" aluminum grating provides an enhanced walking surface for areas subject to continuous pedestrian traffic.
DT style aluminum gratings are manufactured T bar aluminum plate, have deep rectangular cross bars and are manufactured by inserting pre-punched bearing bars and cross bars into an interlocking configuration and deforming the cross bars under intense hydraulic pressure.
