The Fortress Box Frame Slide Gate, manufactured by TYMETAL, is a cantilever system designed to handle the forces of gravity and wind, using box frame construction and stainless steel cable. Diagonal cross members eliminate lateral sway while numerous design features are necessary for single gates with widths up to 60 feet, 120 feet for doubles, addressing potential stresses on the gate.
Box Frame Gates are fabricated from 6063-T6 aluminum alloy extrusions with primary members (top and bottom) “P” shaped in the cross-section. The vertical members alternate between 2”x 2” and 1”x 2” in cross section and are spaced at a distance not to exceed the overall height of the box frame. Constructed in “box” form, the width between the frames measures 24” from outside to outside.
Each frame has a track of extruded aluminum alloy welded to the primary member allowing the gate to operate smoothly. The gate frame is supported from the two tracks by fourself-aligning, 4-wheeled, sealed lubricant ball-bearing truck assemblies. The gate includes cross bracing of 3/16” minimum diameter stainless steel cable to provide for vertical adjustment.
For special applications with limited backspace or larger openings, telescoping or roller box frame gates are also available.
