Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.

Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

Pet cages can be used for indoor and outdoor pet houses. The dog cage is equipped with a fixed food basin and a drinking device, and the rubber pad of the pet cage with a bayonet on the four sides can be assembled. Can be splicing according to the size of the cage, shear, disassembly convenient, easy to clean, can solve the puppy in the ordinary cage pinched foot problem, prevent the puppy in the development of adverse reactions. The bulkhead of the pet cage is breathable and comfortable, which can be used as a heat shield for pets in summer. A puppy with small feet, not a foot, not a pinch.

Electric galvanized wire is dipped in the zinc solution of heating ablation, the production speed is fast, the coating is thick but not uniform, the market allows a low thickness of 45 microns, up to 300 microns or more. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.

Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
