20d nails

Heavy hexagonal mesh is made of low carbon steel wire galvanized large wire braided, the tensile strength of steel wire is not less than 38kg/m2, the diameter of steel wire can reach 2.0mm-3.2mm, the surface of steel wire is usually hot galvanized protection, galvanized amount can reach 500g/m2.

The characteristics of hexagonal net: strong structure, flat surface, with good corrosion resistance, anti oxidation and other characteristics of the use: used for raising chickens, ducks, geese, rabbits and zoo fence, mechanical equipment protection, highway guardrail, sports venues fence, road green belt protection net. The screen in the production of a box shaped container, filled with stone cage, can be used to protect and support the seawall, hillside, road and bridge, reservoirs and other civil engineering, flood control and flood resistance material, namely (stone cage net, stone cage cage).

When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.

After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
