Description

Galvanized Steel Sheet is also named GC Sheets, which can prevent corrosion of the steel surface to extend its service life. The steel surface coated with a layer of metal zinc because zinc can form a good corrosion resistant film on the surface in corrosive environment. It not only protects the zinc layer itself, but also protects the steel base. Our products has the advantage of good corrosion resistance, painting, decorative and good formability. It is mainly used in automobile, home appliances, architecture, machinery, electronics, light industry and other industries.

Electro Galvanized Vs Hot Dip Galavnized

The electrogalvanized layer has a thickness of 5 to 15 μm, and the hot-dip galvanized layer is generally 35 μm or more, or even as high as 200 μm. Hot-dip galvanizing has great advantages in oxidation resistance and rust prevention. Relatively speaking, the zinc layer of electro-galvanized is thin, the price is low, and the production process is simple. In some important industries in many countries, the use of electro-galvanized steel has been banned. For some industries with short cycle times and low anti-rust requirements, there is still a certain market.


Production Technology:

  • intra line annealing and off-line annealing, namely

  • the protection gas method and flux method.


Common Problems in Galvanized Steel

The main reasons for the loss of zinc layer of galvanized steel corrugated sheets is NOF section oxidation atmosphere, too high dew point of protecting gas, unreasonable air combustion ratio, low hydrogen flow rate, oxygen infiltration of furnace, low temperature of strip, low NOF Duan Luwen, low oil evaporation, low content of aluminum in zinc pot, speed of unit too fast, reduction The time of residence in zinc liquid is too short, and the thickness of coating is too thick in manufacturing galvanized steel

Professional production and high technology can avoid effectively zinc layer shedding, scratching, passivating spots, zinc particles, thick edges, gas knife scratches, air knife scratches, exposed steel, inclusions, mechanical damage, steel base performance, wave edge, ladle curve, size incompatibility, imprint, incompatibility of zinc layer thickness, roll print, etc. This depends on the production experience, production management and inspection system of the galvanized sheet production company, and more is the production responsibility of the producer itself.
