JIS G3302 SGCC Hot Dipped Galvanized Steel Coil Z60–Z275 for Industrial Freezers and Building Applications

JIS G3302 SGCC Hot Dipped Galvanized Steel Coil Z60–Z275 for Industrial Freezers and Building Applications

１．Product Overview

Hot dipped galvanized steel coil is manufactured according to JIS G3302, ASTM A653, and EN 10147 standards. The product combines a steel substrate with a protective zinc coating to provide corrosion resistance and long service life in indoor and outdoor environments.

It is widely used in industrial freezers, refrigeration equipment, roofing systems, wall panels, ovens, ventilation equipment, and general building materials where corrosion protection and forming performance are required.

２．Technical Solution

The steel strip is continuously galvanized through a hot-dip process, forming a zinc layer on both sides of the substrate. The zinc coating acts as a sacrificial barrier that helps protect the steel from corrosion during service.

Passivated, oiled, and anti-finger surface treatments are available to improve storage stability, transportation performance, and resistance to handling marks. Multiple spangle options support both decorative and industrial applications.

The product is suitable for roll forming, profiling, bending, stamping, and fabrication operations commonly used in refrigeration and construction industries.

３．Specifications

４．Application

This galvanized steel coil is commonly used for industrial freezers, refrigeration cabinets, cold-room panels, roofing sheets, exterior wall systems, garage doors, ventilation equipment, ovens, appliance components, storage facilities, and building structures.

It is also suitable for further processing into galvanized sheets, corrugated roofing panels, structural profiles, and insulated construction systems.

５．Processing

The product supports slitting, cut-to-length processing, roll forming, bending, punching, stamping, profiling, and fabrication.

Customized widths and coil specifications can be supplied according to production requirements. Export packaging includes edge protection, steel strapping, and wrapped coil protection for long-distance transportation.

６．Advantages
