Frequently Asked Questions about Wanzhi Steel Galvanized Steel

What is Galvanized Steel?

Galvanized steel, abbreviated as GI steel, is usually sold in coils and sheets. It is a common raw material for construction, transportation, appliances, and machinery manufacturing.

What are the Components of Galvanized Steel?

Galvanized steel is a metal-coated steel coil made from hot-rolled or cold-rolled steel strips with a hot-dip galvanized or electro-galvanized surface.

  • Substrate: Cold rolled steel, hot rolled steel (Q195-Q345/SGCC/SGCC, SGCD1/DX51D, DX52D, DX53D, DX54D/G30, G60, G90…)
  • Coating: Zinc layer thickness 40–150 microns, Zinc layer weight Z20-Z350g.

Why Choose Galvanized Steel?

Versatile, corrosion resistant, toughness/rigidity/plasticity/bending/cold workability/durability.

What is the Price of Galvanized Steel?

The price of regular galvanized steel without zinc coating is 600-800 USD per ton.

What are the Methods of Galvanizing?

Wanzhi Group mainly uses hot-dip galvanizing and electro-galvanizing processes.

What is the Maximum Service Life of Galvanized Steel?

Galvanized steel has a service life of 7-50 years in normal environments. (This is mainly due to the thickness of the zinc layer).

What is Hot Dip Galvanizing?

It refers to the process of galvanizing steel by immersing it in molten zinc at high temperatures.

What is Electro Galvanizing?

It is the process of depositing a layer of zinc on the surface of steel by electrolysis.

Which is better, Electro Galvanizing or Hot-dip Galvanizing?

Electro-galvanized steel has a smooth surface but a thin layer of zinc, hot-dip galvanized steel has a rough surface but a thicker layer of zinc. Hot-dip galvanized steel is generally more versatile, and electro-galvanizing is preferred for more delicate surface finishes.

Does Galvanized Steel Rust?

Yes, regular cleaning and maintenance are required to protect the zinc coating during storage and use.

How can I Extend the Life of Galvanized Steel?

Galvanized steel can be treated with surface treatments such as oiling, phosphating, coating, sealing, painting, etc.

How do I Store Galvanized Steel?

Galvanized steel should be stored in a dry, well-ventilated environment, protected from moisture and impacts, and wiped dry if wetted by rain.

What are the applications of galvanized steel?

Commonly used in building structures, fences, shelves, transportation facilities, etc.

What are the Standards of Galvanized Steel?

GB/T708 GB/T5213, EN10130, JIS G3141, ASTM A653.

Which is Better, Galvanized Steel or Stainless Steel?

Stainless steel has better corrosion resistance and longer service life. Galvanized steel has a lower cost.

Can you Provide Samples of Galvanized Steel?

Wanzhi Group can provide samples of galvanized steel in different materials and specifications.
