Z10 Z27 Hot Dipped Galvanized Steel Strip 300-400mm Width for Construction and Welded Pipe Applications

Z10 Z27 Hot Dipped Galvanized Steel Strip 300-400mm Width for Construction and Welded Pipe Applications

１．Product Overview

Z10 Z27 Hot Dipped Galvanized Steel Strip is manufactured from carbon steel through a continuous hot-dip galvanizing process. The zinc coating provides effective corrosion protection while maintaining good formability and weldability.

Available in widths from 30mm to 630mm and commonly supplied in 300-400mm widths, the product is widely used for welded pipes, construction components, appliance parts, packaging materials, automotive components, and general industrial fabrication.

２．Technical Solution

The carbon steel strip is continuously immersed in molten zinc to form a metallurgically bonded protective coating on both sides of the steel surface.

The Z10-Z27 zinc coating range provides protection against atmospheric corrosion while supporting forming, bending, profiling, and welding operations. Regular spangle finish offers a traditional galvanized appearance suitable for construction and industrial applications.

３．Specifications
