Galvanized Steel Sheet

Your Leading Galvanized Steel Sheet Supplier

Tangshan Zhenxiang Plate and Strip Processing Co., Ltd. stands proud as a beacon in the global plate and strip processing sector. Galvanized steel sheet, also known as electroplated galvanized steel sheet, is characterized by a layer of zinc covering the surface. By immersing in molten zinc solution, the steel plate obtains this layer of zinc protection, thereby achieving excellent anti-corrosion and rust prevention effects. Boasting an impressive annual output of 1 million tons of diverse flat steel and 600,000 tons of premium hot-dip galvanized products, along with nearly 200,000 tons of soil nail scaffolding, the company achieves an astounding annual sales revenue exceeding 2 billion yuan.

Process Flow of Galvanized Steel Sheet

Alkali washing degreasing → water washing drying;

Reducing atmosphere annealing;

Zinc dipping solution → air knife controlled zinc amount;

Zinc flower control (rapid cooling to form small zinc flowers);

Polishing and passivation treatment.

Surface Treatment of Galvanized Steel Sheet

Degreasing/Caustic Cleaning

A hot alkali solution, mild acidic bath, or biological cleaning bath removes organic contaminants such as dirt, paint markings, grease, and oil from the metal surface. Epoxies, vinyls, asphalt, or welding slag, which cannot be removed by degreasing, must be removed before galvanizing by grit-blasting, sand-blasting, or other mechanical means.

Pickling

A dilute solution of heated sulfuric acid or ambient hydrochloric acid removes mill scale and iron oxides (rust) from the steel surface. As an alternative to or in conjunction with pickling, this step can also be accomplished using abrasive cleaning or air blasting sand, metallic shot, or grit onto the steel.

Fluxing

The final surface preparation step in the galvanizing process, a zinc ammonium chloride solution, serves two purposes. It removes any remaining oxides and deposits a protective layer on the steel to prevent any further oxides from forming on the surface prior to immersion in the molten zinc.

Q: What is galvanized steel sheet used for?

A: Galvanized metals are used everywhere! The bodies of cars and many bicycles are made from galvanized metals. Some drinking water pipes are still made from galvanized steel. Cool rolled sheet metal is also frequently galvanized.

Q: Does galvanized steel sheet rust?

A: Due to its smooth surface, should the galvanised steel sheet incur any damage, the integrity of the protection is compromised, making it prone to rusting. Fortunately, this makes it easily noticeable on regular inspection and therefore can be treated quickly and effectively.

Q: Is galvanized steel sheet waterproof?

A: Galvanized steel offers excellent resistance against water and chlorine but pales in comparison to stainless steel's corrosion resistance when dealing with marine environments. The protective layer on galvanized is also not self-healing like the passive layer on stainless steel.
