Glaro Satin Aluminum Commercial Waste Receptacles are Rust Proof and Tarnish Proof. Each outer receptacle cylinder is constructed from heavy gauge rolled aluminum that has been carefully satin finished. The Satin Aluminum tops are made from heavy gauge, seamless aluminum, and hand formed by Glaro's unique metal spinning process. The Glaro waste receptacle tops are then satin polished by hand and finished with a permanent, high temperature baked clear powder coat finish. The result is a permanent corrosion-free surface that is maintenance free and is easy to clean. Glaro Satin Aluminum Commercial Waste Receptacles include a fireproof, galvanized steel innercontainer with a full "lift out" handle for easy removal of refuse and a noncorrosive, non-rusting aluminum bottom.
