The Riser Platform is a lightweight platform, suitable for seating riser applications. Like our standard SC90® Platform, the Riser Platform is constructed with an extruded aluminum frame that is combined with a sturdy 3/4″ marinetech plywood substrate with an aluminum backer that provides a Class A fire rating. The Riser Platform is available in standard and custom sizes for both indoor and outdoor use. Standard sizes include 3′ x 8′ (.92 m x 2.44 m), 3′ x 6′ (.92 m x 1.83 m), 3’ x 4’ (92 m x 1.22 m), and 3’ x 3’ (.92 m x .92 m). A full line of accessories is available, as well as multiple surface options.
