galvanized concertina wire

Galvanized steel wire gabion net is a steel wire gabion and a kind of gabion net. It is made of high corrosion resistance, high strength and ductility low carbon steel wire (what people generally call iron wire) or PVC coated steel wire. Mechanically braided. The diameter of the low carbon steel wire used varies according to the engineering design requirements. It is generally between 2.0-4.0mm. The tensile strength of the steel wire is not less than 38kg/m2. The weight of the metal coating varies depending on the site. The materials generally include electro-galvanized, hot-dip galvanized, high-grade galvanized, and zinc-aluminum alloy. Technical requirements for galvanized steel wire gabion mesh 1. Galvanized steel wire gabion mesh is made of anti-corrosion low carbon steel wire. The interior is divided into independent units by partitions. The length, width and height tolerances are +-5%. 2. The galvanized steel wire gabion mesh is produced in one step, and the partitions are double partitions. Except for the cover plate, the side plates, end plates, and bottom plates are inseparable. 3. The length and width of galvanized steel gabion mesh are allowed to have a tolerance of +-3%, and the height is allowed to have a tolerance of +-2.5cm. 4. The grid specification is 6*8cm, the allowable tolerance is -4+16%, the diameter of the grid wire is not less than 2cm, the diameter of the edge wire is not less than 2.4mm, and the diameter of the edge wire is not less than 2.2mm. 5. A professional flanging machine is required to wrap the mesh steel wire around the edge steel wire with no less than 2.5 turns, and manual twisting is not allowed. 6. The tensile strength of the steel wire used to make galvanized steel wire gabions and twisted edges should be greater than 350N/mm2, and the elongation should not be less than 9%. The minimum length of the steel wire sample used for testing is 25cm, and the diameter of the grid wire A tolerance of +-0.05mm is allowed, and a tolerance of +-0.06mm is allowed for the diameter of the edge steel wire and the twisted edge steel wire. The steel wire should be tested before the product is made (to eliminate the influence of mechanical force). 7. Steel wire quality standards: The service life of the steel wires used in galvanized steel wire gabion nets shall not be less than 4a, that is, the anti-corrosion coating will not peel or crack within 4a.
