Box Frame Roller Gate (Manual Operation)
Product Notes
- Closes single clear opening widths up to 250’ and double clear openings up to 500’.
- For larger clear opening widths contact TYMETAL. Clear opening widths for all security gates will vary depending on several factors, including infill options, wind load, and location. Custom widths are available.
Product Summary
TYMETAL’s Fortress Box Frame Roller Gate represents a dramatic breakthrough in the design, construction, and performance of large roller gates by using a specially designed wheel system. Openings up to 500 feet have been protected using this design. Contact us today to discuss this barrier in more detail. We also invite you to request drawings and specifications and take advantage of our extensive in-house resources.

Chain Link Specs Features & Benefits
When the gate is operating under normal load, the wheels run on the flat surfaces of the top and side of a steel beam. As wind begins to put lateral pressure on the gate, the width of the wheel system and its low center of gravity tends to keep the gate in place. However, when the wind load is strong enough to cause the wheels to lift from the beam, the safety guides come in contact with the underside of the top flange of the track and the gate remains safely anchored to the ground.
Our Box Frame Roller Gates are fabricated from 6000 Series aluminum alloy extrusions. The primary members (top and bottom) are “P” shaped in cross-section. The vertical members alternate between 1” x 2” and 1” x 1” in cross-section and are spaced apart at a distance not to exceed the overall height of the box frame. The gate is constructed in “box” form with the width between the frames measuring 24” from outside to outside.
Roller wheel trolley assemblies are bolted to the box frame and pre-specified intervals. Each assembly consists of several steel members which are welded together to provide the support to which the axle is secured. The gate rolls on two parallel tracks which are embedded in concrete so that the top of the track is level with the ground surface.

Frequently Asked Questions
TYMETAL has been in the perimeter security solutions market since 1985. With more than three decades of experience designing, manufacturing, and installing the Box Frame Roller Gate (Manual Operation), we have encountered many questions along the way. Explore a few of the common questions we are asked below. If you don’t find the answers you’re looking for, feel free to contact us by phone at 888-978-4283 or online.
What distinguishes the box frame roller gate design from cantilever or overhead models?
TYMETAL box frame roller gates use a tracked roller system at the base of the gate panel rather than the cantilever’s overhead support or the elevated track of an overhead gate. This ground-level roller track provides stable support for very heavy or wide gate panels, making the box frame roller gate practical for large industrial openings where overhead structural support is not available.
How does the gate’s roller assembly manage load distribution on long spans?
The box frame construction spreads the gate panel’s weight across multiple roller contact points along the bottom rail, preventing the concentrated loading that would occur with a simple tube frame on a wide span. This distributed support reduces track wear, minimizes panel deflection, and allows the gate to operate smoothly across widths where a lighter-gauge panel would flex or bind.
What materials and coatings are used for corrosion resistance in harsh climates?
TYMETAL box frame roller gates are fabricated from aluminum with an industrial powder coat finishes available for corrosive, coastal, or industrial environments.
Are automation and safety sensors compatible with box frame roller designs?
TYMETAL box frame roller gates are compatible with heavy-duty electromechanical and hydraulic operator systems scaled for the gate’s weight and operating forces. UL 325-required safety devices including photo eyes, loop detectors, and obstruction sensors can be integrated into the installation, and the gate supports standard access control interface configurations.
What foundation or track requirements are needed for installation?
Box frame roller gate installations require a level concrete track pad extending the full travel length of the gate, with a precision-installed steel track embedded in or mounted to the concrete surface. The foundation must support the full dynamic load of the gate in motion, and track alignment is critical to ensure smooth roller travel and proper gate closure.
