Order Information

*Deflection should be limited to 1/4½ under 100# uniform load to afford pedestrian comfort.

NOTE: Quite often there is some question as to whether alloy 6063-T6 or 6061-T6 should be the preferred alloy for grating products. The design of aluminum grating for pedestrian loads is deflection limited, rather than strength limited. Although alloy 6061-T6 is stronger than alloy 6063-T6, the Modulus of Elasticity for both alloys is the same: 10,000,000 psi. As a result, equal loads will produce the same deflection, provided, of course that the yield strength is not exceeded.

Aluminum Grating is best suited for use in conjunction with pedestrian traffic, and for very light, rubber pneumatic tired rolling traffic (carts, dollies and hand trucks). For other rolling loads (forklifts, cars, trucks, etc.) see Heavy Duty Steel Grating.
