Security fencing is a superior security barrier for perimeters and critical infrastructure assets. Security fence is available in single or double skin for ultimate protection. The panels and posts are jointed together with bolts or rivets, using the steel flat bar, or special steel clamps. All nuts are self-locking. The system can be installed with a vertical or horizontal mesh alignment. The system can also be mounted onto existing chain link style posts to retrofit current chain link fence installations. The mesh spacing is designed to prevent climb and it is difficult for normal hand tools to penetrate the fence, giving high levels of perimeter protection. All the security fences are made under quality control through the processing of manufacturing.The forms of corrosion resistance for security fencing include electro galvanizing, hot-dipped galvanizing, PVC coating or spraying. Security Fence Material: Normal tensile strength carbon steel High tensile strength carbon steel Al-mg alloy wire Surface treatment of Security fence: 1) Use the hot-dipped galvanized (or electro galvanized) wire as material,after welding,begin PVC or plastic spraying. 2) Use the low carbon steel wire welded the panel,then electro or hot-dipped galvanized treatment, finally PVC treatment. 3) In Europe,generally choose the galvanized after welding or PVC after welding.
