  • Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.

  • It is generally believed that the positive and negative twisting wire wire is not as durable as the thickness, common sense thinks so, but the positive and negative twisting wire wire is used in hot galvanized steel wire, which is more than 3 times the tensile strength of the iron wire, and the zinc amount is not lower than the hot plated wire
  • And the air humidity is large, continuous rainy weather, or the environment with large acidity in the air is easy to rust. 304 stainless steel material, if the surrounding environment is too poor will rust.
