ASTM A653 G90 Hot Dipped Galvanized Steel Strip 0.42mm × 100mm DX52D+Z for Industrial Panels and Structural Components

ASTM A653 G90 Hot Dipped Galvanized Steel Strip 0.42mm × 100mm DX52D+Z for Industrial Panels and Structural Components

１．Product Overview

ASTM A653 G90 hot dipped galvanized steel strip is manufactured from DX52D+Z steel substrate with a zinc coating weight of 180g/m². The product combines corrosion resistance, formability, and dimensional consistency, making it suitable for industrial panels, structural components, appliance parts, pipe manufacturing, and building applications.

The 0.42mm thickness and 100mm width specification is widely used in roll forming, stamping, profiling, and fabrication processes requiring reliable galvanized protection.

２．Technical Solution

The steel strip is produced using a continuous hot-dip galvanizing process. A metallurgically bonded zinc layer is formed on the steel surface to provide sacrificial corrosion protection.

DX52D+Z grade offers enhanced forming performance compared with standard commercial grades, making it suitable for bending, stamping, and shaping operations. Surface treatments such as chroming, skin pass, oiling, and dry treatment can improve storage stability and downstream processing performance.

３．Specifications

４．Application

This galvanized steel strip is suitable for industrial panels, roofing systems, steel structures, greenhouse pipes, gas pipes, heating pipes, appliance housings, kitchen equipment, automotive corrosion-resistant components, refrigeration equipment, packaging materials, and storage systems.

Its combination of corrosion resistance and formability makes it suitable for both construction and manufacturing industries.

５．Processing

The strip supports slitting, cutting, punching, stamping, roll forming, profiling, bending, and welding operations.

The 100mm strip width is commonly used for automated production lines, structural profiles, brackets, and fabricated components.

６．Advantages

• G90 zinc coating provides enhanced corrosion resistance for industrial and construction applications.
• DX52D+Z offers improved forming capability for bending and shaping processes.
• Regular spangle surface delivers a uniform galvanized appearance.
• Multiple surface treatment options support different storage and fabrication requirements.
• Hot dip galvanizing creates strong coating adhesion and long-term protection.
