DX51D DX52D Z60 Z275 Hot Dipped Galvanized Steel Strip Grade 50 for Construction and Pipe Manufacturing

DX51D DX52D Z60 Z275 Hot Dipped Galvanized Steel Strip Grade 50 for Construction and Pipe Manufacturing

１．Product Overview

DX51D DX52D Z60 Z275 Hot Dipped Galvanized Steel Strip is manufactured from carbon steel through a continuous hot-dip galvanizing process. The zinc coating forms a protective layer on the steel surface, providing corrosion resistance for construction, pipe manufacturing, appliance production, packaging, and automotive applications.

Available in zinc coating ranges from Z60 to Z275, the product combines good formability, weldability, and corrosion protection for both indoor and outdoor service conditions.

２．Technical Solution

The steel strip is continuously immersed in molten zinc to create a metallurgically bonded coating on both sides of the steel substrate.

Z60 coating is suitable for general-purpose applications, while Z275 provides enhanced corrosion protection for more demanding environments. Regular and big spangle surfaces are available depending on appearance and application requirements.

The product can be supplied in coil form and processed through slitting, cutting, roll forming, welding, and profiling operations.

３．Specifications

４．Application

This galvanized steel strip is widely used for welded greenhouse pipes, gas pipes, heating pipes, roofing structures, roof grilles, appliance housings, kitchen equipment, automotive corrosion-resistant parts, packaging materials, refrigeration equipment, storage systems, and transportation equipment.

It is also suitable for industrial and civil construction projects requiring long-term corrosion protection.

５．Processing

The material can be supplied in coil, slit coil, or cut-length form according to customer specifications.

Supported processing methods include slitting, cutting, bending, welding, stamping, profiling, roll forming, and fabrication.

Customized dimensions and packaging can be arranged according to project requirements.
