Designed to US Postal Service security specifications, the Steel-Lite’s fire, vandal and shock-resistant design offers a high level of security in a multitude of applications.
A fully welded steel sub-frame supports facings of 16 gauge galvanized steel. Heavy duty bumpers, cane bolts, window bars and more add security muscle. Full gaskets seal off temperature, sound and dust intrusion. Proven cast Mechanite V-cam hinges with sealed bearings deliver smooth 180° swing.
Door Panel - The ¼” thick monolithically formed outer shell is rotationally molded from Cross-Linked High Density Polyethylene (X-LINK HDPE). This material is five times stronger than ABS and offers maximum durability and impact resistance. The Cross-Linked High Density Polyethylene material maintains its properties to –40°F. Overall panel thickness is 1-7/8”.
Insulated Core – The door panel core is foamed in place CFC-Free urethane foam which permanently bonds to the inner surface of the door panel. This ensures that the foam will not break down when the door is impacted. The CFC-Free foam core provides excellent insulation (R Factor of 10.83) and sound attenuation properties.
Internal Reinforcement – Upper V-Cam Hinge System, lower hinge pillow block construction with UHMW sleeve and solid cast aluminum adapter.
High Density Polyethylene Spring Bumpers - 38” High Density Polyethylene (HDPE) spring bumpers protect the door panel from impact. These bumpers feature a 4” teardrop projection that compresses to absorb the energy created by impact from carts and man-ridden vehicles. The bumper them “springs” back to its original position.
Full Perimeter Gasketing - Durable gasketing is factory applied without the use of metal strips or fasteners, making it easy to replace in the field. Frame mounted header seals are supplied to seal the top of the door.
Upper Hinge System - Solid cast aluminum Upper Hinge Post and a zinc-plated ductile iron V-Cam with UHMW sleeve for smooth, reliable operation. The roller assembly features a permanently lubricated needle bearing for durability and minimal maintenance.
Bottom Hinge - Solid cast aluminum lower hinge post rides in heavy duty lower pillow block with UHMW sleeve for smooth, reliable operation. The lower hinge post can accommodate our optional spring assist for high draft applications.
