- The color of powder coating is divided into: razor wire blue, grass green, dark green, yellow. Plastic-sprayed blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of resistance devices. Because the shape of the barbed rope is not easy to contact, so it can reach an excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, plastic coated, plastic spraying) wire, blue, green, yellow and other colors.
Because the large volume of galvanized wire alloy elements in iron ore, can make the copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
Stainless steel barbed wire in the way of corrosion is not too, because the surface is not treated but relies on its own raw materials for corrosion resistance, so there will be no chemical reaction.
