The zinc coating forms a protective barrier between the steel substrate and the surrounding environment, reducing rust and corrosion caused by moisture and air.
Galvanized steel requires less maintenance than untreated carbon steel and is suitable for long-term indoor and outdoor applications.
The galvanizing process retains the mechanical properties of the base steel, making the products suitable for load-bearing structures and industrial components.
Hot-dip galvanizing can protect edges, corners, joints and other areas that are difficult to cover evenly with conventional paint.
Galvanized steel can be cut, bent, punched, drilled and assembled according to project drawings and installation requirements.
Its long service life and reduced maintenance requirements help lower the total cost of construction and ownership.

Galvanized steel is carbon steel coated with zinc to protect the base material against rust and corrosion.
Pre-galvanized steel is produced from continuously galvanized coils before fabrication. Hot-dip galvanized steel is immersed in molten zinc after the component has been manufactured, providing more complete coverage of edges, welds and corners.
Yes. The zinc coating can be selected according to the product type, service environment, corrosion requirements and project specifications.
Yes. Galvanized steel can be welded using suitable procedures, ventilation and surface preparation. Fabricated components can also be welded first and hot-dip galvanized afterward.
Yes. We can manufacture galvanized steel components according to drawings, samples, material lists and technical specifications.
