  • The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.

  • Barbed wire even in the mining industry also has a higher embodiment, because the selection of low-carbon materials to make it has a general iron mesh does not have the flexibility, determined its plasticity in the use, and then can be used in hardware crafts in the deep processing production, as the wall plastering, inside leak prevention crack and so on. Its light net body, the lower cost, can let the customer realize its economic benefits.

  • Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
