Defensive barrier/defensive gabion

Defensive barrier, also known as gabion barrier and defensive bastion, is a new product assembled and sewn from welded gabion mesh and geotextile, which has the ability to resist explosive shock waves and limit the destructive effects of explosions to a certain range. Compared with reinforced concrete explosion-proof walls, it has the advantages of light weight, easy installation, disassembly and recycling.

Surface treatment of defensive barrier

Hot dipped galvanized before welded (common zinc layer) : 40 -80 g/㎡，The zinc layer is thin and has average corrosion resistance, making it suitable for use in dry, low rainfall environments.

Hot dipped galvanized before welded (thick zinc layer) : 240 – 260 g/m,The amount of zinc is thick, suitable for various environments and a wide range of applications, making it the choice of many customers.

Hot dipped galvanized after welded (thicker zinc layer ) : 450 -500 g/㎡，The amount of zinc is so thick that it will last for many years, even in a constantly humid, salty environment.

Zinc – 5% aluminum wire : Zinc-aluminum alloy wire is a new type of material whose main advantages are better plasticity and adhesion of the coating and much higher resistance to atmospheric corrosion than conventional hot-dip galvanizing.
