Downloads Page for the Box Frame Roller Gate

The Fortress Box Frame Roller Gate, engineered by TYMETAL, marks a significant advancement in the design, construction, and performance of large-scale roller gates. This innovative system utilizes a uniquely designed wheel assembly that allows openings up to 500 feet to be effectively secured. Under normal load conditions, the wheels glide smoothly along a W4 x 13 "I" beam track, making contact with the top and sides of the steel beam. As wind pressures increase, the wide wheel system and its low center of gravity help stabilize the gate. However, if the wind load becomes strong enough to lift the wheels off the track, the safety guides come into play, contacting the underside of the track flange and ensuring the gate remains securely anchored to the ground. These Box Frame Roller Gates are crafted from 6063-T6 aluminum alloy extrusions. The main horizontal members (top and bottom) have a "P"-shaped cross-section, with each side measuring at least 2 inches and weighing no less than 1.6 lbs per linear foot. The vertical members at the ends of each panel section are 2"x2", weighing at least 1.1 lbs per foot. Intermediate vertical members alternate between 1"x2" and 1"x1", weighing no less than 0.82 lbs and 0.52 lbs per linear foot, respectively. These members are spaced at intervals not exceeding the overall height of the box frame. The gate is constructed in a "box" configuration with the width between the frames measuring 24 inches from outside to outside. Inside the frame, a continuous series of 1"x1" diagonal and horizontal bracing is welded at approximately 45 degrees to the frames. At predetermined intervals along the box frame, roller wheel trolley assemblies are bolted securely. Each assembly comprises several welded steel components that provide support for the axle. The gate rolls on two parallel tracks embedded in concrete, ensuring the top of the track is flush with the ground surface. For the TYM-HYD Box Frame Roller Gate System with a hydraulic operator (chain link), Part 1 – General includes the provision of all labor, materials, equipment, and accessories needed to complete the required Fortress Box Frame Roller Gates and hydraulic operator systems. Referenced standards include Underwriters Laboratory Gate Operator Requirements (UL 325), ASTM F 2200 – Standard Specification for Automated Vehicular Gate Construction, American Welding Society AWS D1.2 Structural Welding Code, and ASTM A 123 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel. Submittals required include product data, shop drawings, and certifications regarding welding procedures and qualifications. Additionally, each operator must bear a label certifying it has undergone full power and pressure testing of hydraulic components, stress tests of mechanical components, and electrical tests of overload devices. Part 2 – Products outlines the specifications for the hydraulic gate operators, including the TYM-HYD-VF2 model, which uses a hydraulic, roller-type motor. The operator generates a minimum horizontal pull of 300 pounds and can handle gates weighing up to 5,000 pounds. The system incorporates a variable frequency drive (VFD) for smooth acceleration and deceleration, and it features multiple safety sensors to reverse the gate upon detecting obstructions. Part 3 – Execution details the site inspection, installation, and system validation processes, emphasizing compliance with ASTM F 2200 and UL 325 standards. It also highlights the importance of installing appropriate external safety devices and verifying their proper operation. The TYM-HYD Box Frame Roller Gate System with a hydraulic operator (ornamental) follows similar guidelines but specifies ornamental pickets for the gate filler, ensuring compliance with ASTM F 2200 and UL 325 standards while maintaining aesthetic appeal. TYMETAL continues to refine and enhance its products, ensuring they meet the highest safety and performance standards. This comprehensive approach ensures that every aspect of the gate system—from design and fabrication to installation and maintenance—is executed with precision and attention to detail. TYMETAL remains committed to innovation and excellence, offering reliable solutions for securing industrial facilities.

Natural Rubber Sponge Series

Our G5 series natural rubber foam is made out of natural rubber harvested from rubber trees, plant-based and latex-allergy friendly natural rubber rather than the traditional petroleum-based and limestone-based neoprene. Compared to the traditional neoprene sheets, the natural rubber wetusits production process saves up to 80% on CO2 emissions in one wetsuit. And our all G5 rubber plantations are 100% FSC® certified. FSC® certified means that buying your new G5 natural rubber wetsuit does not contribute to deforestation, human right violations or abuse of agricultural pesticides. It also means that the hevea rubber – the main ingredient G5 natural rubber foam is only extracted from plantations that preserve ecological integrity and biodiversity. Though only 4% of global rubber plantation area is currently FSC®-certified, well-managed FSC®-certified forest management has the potential to affect a positive environmental and social transformation of the natural rubber sector.
