    General Specifications - Grating

    United Interlock Grating is engineered with a strength-to-weight ratio that allows it to withstand substantial loads while being easy to handle. The male-female legs of the roll-formed grating interlock securely, and double-male legs provide a safe finished edge for end planks.

    Two standard surfaces are available: slottedsmooth and anti-skid. Anti-skid is the ideal choice when safe walking conditions are important. Dieformed teeth in the transverse ribs give you 360° of shoe-gripping traction even when the grating is wet, oily, muddy, or icy.

    Punched Interlock Grating has an open area of 42% for 9" grating and 35% for 6" grating. This prevents dirt, debris, ice, and snow from building up on the surface and allows light and air to pass through. United Interlock steel grating is made from pre-galvanized steel which conforms to a G-90 thickness designation per ASTM A653. The aluminum grating is made from type 5052 aluminum with a thickness of 0.080".

    Unpunched smooth surface grating is also available for special applications.
