Aluminum grating is a versatile option for special grating applications where environments require unique consideration.

Aluminum offers:
- light mass
- high strength-to-weight ratio
- high corrosion resistance
The most common method of manufacturing aluminum bar grating is through a process known as pressure locking. Pressure locked grating as defined by the NAAMM Metal Bar Grating Manual is "Grating in which the cross bars are mechanically locked to the bearing bars at their intersections by deforming or swaging the metal." Direct Metals has taken advantage of the most modern technology available to provide a permanently attached pressure locked joint which will give long lasting life under normal service conditions.
Aluminum Rectangular Bar:
A type of pressure locked aluminum bar grating made by permanently attaching cross bars to bearing bars through a pressure applied swaging process. Bearing bar sizes range from 1" x 1/8" through 2 1/2" x 3/16” in 1/4” increments. Bearing bar spacing of 1 3/16”, 15/16”,11/16” and 7/16” c.c., with cross bar spacing of 4” or 2” are available. Where skid resistance is desired, a serrated surface can be provided.
