Aluminum Heavy Duty Plank Grating is a structurally sound and attractive alternative to regular bar grating. It is made in 6" wide sections of extruded aluminum up to 26' long. PMWI Aluminum Plank Grating has a built in chamfer on the bottom side of the plank that allows multiple sections to be easily welded together to form required panel sizes. Our plank grating is available in 8 different grating depth sizes ranging from 3/4" to 2-1/2".​ The plank surface can be provided unpunched or rectangular punched to allow the passage of air, light, heat, or moisture.
