Steel face sheets shall be 24 Therma-Tru galvanized tension leveled steel for superior flatness & enhanced corrosion resistance.
Paint Finish- Doors shall receive a factory prime finish for added rust inhibition. Primed surface shall be suitable for maximum adhesion of finish top coat.
Insulated- Doors shall be foamed in place, stiffened & structurally reinforced with environmentally friendly polyurethane and bonded to inside skins with minimal voids.
Rugged Construction- The door edges shall be mechanically overlapped and reinforced the full height on both sides of door and adhered with foamed in place polyurethane. The door shall be stiffened with integrally formed top and bottom rails securely welded at top and bottom of door with two welds each.
Advanced Lock Reinforcing -Latching and deadlocking hardware is supported with an advanced injection molded composite lock reinforcement with superior screw holding power. Advanced door avoids the problem of 'telegraphing' of the lock reinforcement typical with wood blocks. Design also allows for uniform foam flow for a flatter door face at lock area.
