Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium
chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

our advantage
(1)Quality Zhongxiang steel introduces the advanced testing equipments and builds up a professional scientific research team, strictly control the quality on each steps of production. including inspection on raw materials entry, product's color analysis during production,T-bend test, impact test, salt-spray test, tensile test and packaging testing on exported products , which ensures its integrated performance such as corrosion resistance, Coating stickiness etc and the safety of transportation.
(2)Service Nowadays, the economic globalization is facilitating international operation, our company go to many countries and regions to participate in the steel industry exhibition. our Products sell pretty well not only in domestic market, but also prevails in Europe,such as southeast Asia, Russia, Ukraine, the United States, Ireland, Singapore, Dubai, Colombia and other countries and regions, which has earned the customers trust & compliment and successfully transitioned from home to abroad.
Application areas:
Because galvanized coil has strong corrosion resistance, good surface quality, conducive to deep processing, economic and practical characteristics, so it is widely used in construction, household appliances, automobiles, containers, transportation and household industries and other fields. Especially steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries.
