ADA Punched Aluminum Plank Fastener Detail

Diagonal Punch Aluminum Plank

Aluminum Plank

As an alternative to bar grating, aluminum plank is structurally sound and cosmetically attractive. Made from extruded aluminum, plank grating is relatively maintenance free 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. A diagonal pattern is also available which meets the ADA requirements for wheelchair accessibility and high heel foot traffic.

The interconnecting webs offer a flush top walking surface for maximum foot contact and comfort. Plank can be used as an alternative to those applications requiring open grating with plate attached to the top surface. This is a typical application for waste water treatment plants to help reduce the odor which is inherent at these facilities.

Aluminum Plank is also used for entranceways and walkways for bridges, trails, marine refrigeration, stadiums and more.

Plank meets the requirements of the military specs MIL-G-18014B (Ships) and MIL-G-18015 A (Ships)

Rectangular or square punched holes are most commonly used for water and waste water treatment plants and in marine applications. The surface of plank grating can be specified as plain or with one of two styles of upsets (OGi or WACO) and is designed to promote a slip resistant walkway, especially in the presence of moisture, oil or other spilled substances.
