Design#
BarrierGuard 800 Steel Gate is a hinged steel gate comprising 6 metre and 12 metre sections of Barrierguard 800 steel barrier with “T-Top” attachments. The system is 540 mm wide, and 915 mm high. The maximum length of gate is 30 metres (on the basis of operational manageability). The system is tested on longer lengths. The system should be installed on smooth level ground. The intended sweep of the gate should be free from kerbs or rapid changes in gradient. Designer should check with supplier for site specific foundation requirements.
