Aluminum Plank is an alternative to bar grating and is structurally sound and cosmetically attractive. Constructed from extruded aluminum, plank grating is non-sparkling, non-magnetic, non-skid, and relatively maintenance free. It is durable, corrosion resistant, possesses a high strength-to-weight ratio, and has no parts to work loose or splinter. The surface can be provided unpunched, or with a variety of punch/patterns for the passage of air, light, heat or moisture. The interconnecting webs offer a flush top walking surface. Stair treads are also available, please inquire.
