Grate-Lock® Grating Grate-Lock®/Interlock from Marco Specialty Steel, Inc. is engineered with a strength-to-weight ration 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 surfaces are available: slotted-smooth and anti-skid. Anti-skid is the ideal choice when safe walking conditions are important. Die-formed teeth in the transverse ribs give you 360°'s of shoe gripping traction even when the grating is wet, oily, muddy, or icy.
