Characteristics of Q235 Steel

Plasticity: easy to process and mold.
Weldability: It can be welded and heat-treated.
Low cost: Compared with high-strength steel, the cost is lower.
Surface treatment: Can be galvanized, color coated.

Applications of Q235

Q235 steel can also be divided into different grades according to its tensile strength.

Q235A: For low tensile strength.
Q235B: For general tensile strength.
Q235C: For low-temperature applications.
Q235D: For even lower temperatures.

Q235 Galvanized Steel Process

Galvanized steel Q235 is hot-dip galvanized, which is a thicker layer of zinc, suitable for mass production, and has the lowest cost compared to other plated or coated steels. However, our main galvanizing processes are hot dip galvanizing and electro galvanizing, so you can choose the process that suits your needs depending on your application.

Hot-dip galvanizing: Q235 steel sheet or coil is dipped into molten zinc at high temperatures and a zinc coating is applied to the surface. A spangle is formed on the surface, the size of which can be adjusted.
Electro Galvanizing: The steel coil or sheet is immersed in an electrolytic solution containing zinc ions, which are reduced by an electric current and deposited on the surface of the substrate to form a zinc layer.

Advantages of Q235 GI Steel

  • Low cost
  • Good anti-corrosion properties
  • Good plasticity and weldability
  • Good mechanical properties

Applications of Q235 Galvanized Steel

  • Construction: steel structure, bridge, stair treads, roofing, etc.
  • Machinery: machine parts, automobile shells, hulls, home appliance shells, etc…
  • Piping: drains, water pipes, ventilation ducts, etc.

How to Choose Galvanized Steel for Your Project?

Wanzhi Group has rich project experience in providing Q235 Galvanized steel coil, roofing, gutters, prepainted roofing, etc. Depending on the location of the project, the environment, and the strength of the steel, choosing the steel with different zinc layers and surface treatments will effectively save the cost of the project. It will save the project cost-effectively. (choose the most cost-effective steel rather than the cheapest one. )
