Grate Lock® Interlock 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° of shoe gripping traction even when the grating is wet, oily, muddy, or icy.

Applications:

Catwalks • Mezzanines • Stair Treads • Trench Covers

Product Features:

• Exclusive anti-skid design provides 360° of slip resistance
• Superior ultimate-load performance tested in accordance with AISI standards
• All sections made from structural grade steel
• Roll-formed design provides superior strength
• Optional heel-toe side and end plates
• Open design prevents build-up of water, grease, oil, and small debris

Project Versatility:

• 6" and 9" plank widths allow design in 3" increments
• Standard lengths of 20', 24' and special lengths up to 30', provide excellent design flexibility
• Choice of smooth or anti-skid surfaces
• Three leg heights, and material gauges meet a wide range of load, space and budget requirements.
• Planks are lightweight and install fast by one person. Another advantage is that planks are corrosion resistant galvanized steel.
