The Fortress Box Frame Roller Gate, manufactured by TYMETAL, represents a significant advancement in the design, construction, and performance of large roller gates through the use of an innovative wheel system. This system enables protection of openings up to 500 feet. When operating under normal load, the wheels run on a W4 x 13 "I" beam track, making contact with the top and side of a steel beam. As wind exerts lateral pressure on the gate, the width of the wheel system and its low center of gravity help keep the gate in place. However, when wind load is strong enough to lift the wheels from the beam, safety guides come into contact with the underside of the track's flange, ensuring the gate remains safely anchored.
Box Frame Roller Gates are constructed from 6063-T6 aluminum alloy extrusions. The primary members (top and bottom) are shaped like a "P" in cross-section. Vertical members alternate between 1†x 2†and 1†x 1†in cross-section and are spaced no more than the overall height of the box frame apart. The gate is built in a "box" form, with the width between frames measuring 24†from outside to outside.
Roller wheel trolley assemblies are bolted to the box frame at predetermined intervals. Each assembly consists of several welded steel components that support the axle. The gate rolls on two parallel tracks embedded in concrete, with the top of the track level with the ground surface.
