SAFETY GRATINGDIAMOND-GRIP CHANNELDiamond-Grip Channel is a one-piece metal plank grating manufactured by a coldforming process in the shape of a channel. The web of the channel is the walkingsurface and has rough serrated edges around diamond shaped openings.FEATURES & BENEFITS Serrated edges around diamond shaped openings provide slip resistance underslippery conditions such as snow, ice, grease, oil, etc. One-piece metal construction. Lightweight design provides high strength to weight ratio. Long life span requiring little maintenance. Simple and economical installation as planks are self-framing. Adaptable to cost effective custom fabrication. Can be easily formed in standard channel or custom shapes.MATERIAL SPECIFICATIONSGrating shall be “Diamond-Grip Channel,” manufactured from (see ‘MaterialOptions’ below) and complete with a (1-1/2”, 2”, 2-1/2”, 3”) side channel depth,by AMICO.

Tolerance on manufactured and cut lengthsis 1/8”. When cutting Diamond-Grip , AMICO recommends cutting to full or half diamond increments. Contact sales for actual dimensions. Camber is an expected condition with sheet metal products. While ASTM allowance is generous, AMICO attempts to lessen the effects.

SAFETY GRATINGDIAMOND-GRIP WALKWAYPRODUCT DESCRIPTIONDiamond-Grip Walkway is a one-piece metal plank grating manufacturedby a cold forming process in the shape of an inverted channel. The web ofthe channel is the walking surface and has rough serrated edges arounddiamond shaped openings. The extended flanges support the load and provide a built in kickplate (toeboard).FEATURES & BENEFITS Serrated edges around diamond shaped openings provide slip resistanceunder slippery conditions such as snow, ice, grease, oil, etc. One-piece metal construction complete with a full height toeboard oneach side of the walking surface. Lightweight design provides high strength to weight ratio. Long life span requiring little maintenance. Simple and economical installation as walkways are self-framing. Adaptable to cost effective custom fabrication.MATERIAL SPECIFICATIONSGrating shall be “Diamond-Grip Walkway,” manufactured from (see‘MATERIAL OPTIONS’ below) and complete with an (4-1/2”, 5”) integraltoeboard,by AMICO. MATERIAL OPTIONS ASTM-A-653, G-90 (Z-275) pre-galvanized 14 or 12GA steel. ASTM-A-1011, HRP&O 14 or 12GA steel.www.amicoglobal.com 800.366.2642 7
