Box Frame Roller Gates

Types of Box Frame Roller Gates

Box Frame Roller Gate (BFRG)

For clear opening widths up to 500 feet the Box Frame Roller Gate (BFRG) can secure extraordinarily large openings and, depending on size and application, can be manually operated or automated.  Based on gate panel weight the automated version can operate at speeds up to 3 feet per second (larger gates weighing more than 5000 pounds are limited to a speed of 1 foot per second).  For example, a single BFRG having a clear opening of 190 feet x 8’ high with standard 2” x 2” x 9 gauge steel chain link infill would weigh about 4,550 pounds and could be matched with an operator that can power it at 3 feet per second.  A well-designed track, trolly and stabilizer system allows the BFRG to perform well in higher wind conditions.  Typical applications include airfield runways to control aircraft and vehicular traffic, and to secure airfield hanger locations.

Telescoping Box Frame Roller Gate (TBFRG)

For applications where there is limited space on either side of an opening the Telescoping version of the Box Frame Roller Gate (TBFRG) is an excellent option.  It requires a roll-back space, when in the open position, of 60% to 75% of the clear opening width and utilizes the same track, trolly and stabilizer system as the standard Box Frame Roller Gate.  Single gate clear opening widths to 83 feet, bi-parting to 166 feet.  If automated, speeds up to 2.2 feet per second.
