Description

This robust curtain system is meticulously engineered for durability and performance. The primary curtain features 26-gauge, grade 80 full-hard galvanized steel, continuously roll-formed and treated for exceptional longevity, including galvanization to A.S.T.M. A653-60 standards, an epoxy primer, and a polyester topcoat, all baked for superior adhesion. Enhanced with nylon side stripping and a reinforced bottom bar—a continuous 2″x1-1/2″x12 gauge galvanized steel angle securely fastened with an aluminum retainer and bulb astragal—the system ensures structural integrity. A precision-engineered spring counterbalance, comprising a 26-gauge 9 1/2″ diameter galvanized steel spiral torque tube and 20-gauge galvanized steel drums, minimizes deflection and incorporates helical torsion-type oil-tempered springs designed for 12,500 cycles with a 25% overload factor, mounted on a 1″ minimum 14-gauge galvanized steel tubing. Operational ease is addressed with a rope pull for units up to 10’0″ Wide x 10’0″ High, while larger installations utilize a standard reduction gear chain hoist. The assembly is supported by resilient 3/16″ thick structural steel angles and guided by roll-formed 12-gauge galvanized steel channels (2 7/8″ deep per side). Security is paramount, provided by dual galvanized steel slide bolt locks attached to the bottom bar, suitable for padlocks. The entire system boasts a premium galvanized and pre-painted finish with long-lasting silicone polyester paint, backed by a 25-year film integrity warranty against cracking, peeling, or blistering, alongside an additional guarantee of up to 20 years against chalking and fading, contingent on color selection.
