Engineering Excellence
Unique precision hinges with solid pivoting shaft to minimize wear on moving parts to provide long service life. All center hinges utilize a steel reinforcing backer plate for added structural integrity.Deep tongue and groove section profile adds to the door’s overall structural integrity and its longterm performance

Quality in Every Layer
The structural integrity of each section is enhanced inside and out to offer maximum protection against the elements to provide you with a long lasting surface finish and reduced maintenance cost. The bonding adhesive is applied  to the galvanized coated steel substrate, followed by a durable primer coating. The thick insulating core of high-grade CFC-free polyurethane rigid foam is injected evenly in a continuous computer-controlled process.

Design Size
The standard section heights, 18” and 24” allow evenly placed ribs throughout the entire door height.  The section joints appear seamless and offer a clean and balanced look to any building’s exterior.

With high thermal insulation properties and Stucco-textured exterior/interior surfaces, it allow maximum protection against harsh environment and minimizes the formation of water condensation on the inside door surface.

he uniquely designed FingerGuard™ pinch-resistant section joints prevent fingers from getting caught between the door sections. This increases the safety of your facility and reduces the risk of injuries which may result in worker’s compensation claims.
