Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective way of metal anticorrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into zinc solution melted at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anticorrosion.

Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
