SGCC DX51D Hot Dipped Galvanized Steel Coil Z60–Z275 Chromated Regular Spangle

Product Specification

SGCC DX51D Hot Dipped Galvanized Steel Coil Z60–Z275 Chromated Regular Spangle for Furniture Manufacturing

１．Product Overview

SGCC DX51D Hot Dipped Galvanized Steel Coil is manufactured through a continuous hot-dip galvanizing process that applies a protective zinc coating to the steel substrate. The product combines corrosion resistance, formability, and surface consistency, making it suitable for furniture manufacturing, appliance components, construction profiles, and general fabrication.

Available with regular, minimized, big, or zero spangle finishes, the coil can be selected according to appearance and painting requirements. Chromated and anti-fingerprint surface treatments further enhance corrosion protection and storage stability.

２．Technical Solution

The steel strip passes through a molten zinc bath, forming a metallurgical bond between the steel substrate and zinc coating. This coating provides sacrificial protection against corrosion while maintaining good forming and processing performance.

Different spangle finishes are produced by controlling zinc solidification conditions:

Regular Spangle for standard industrial applications.

Minimized Spangle for painted surfaces.

Zero Spangle for high-quality coating and decorative applications.

Passivation and oiling treatments help reduce white rust during transportation and storage.

８．FAQ

Q1．What is the difference between regular spangle and zero spangle?

Regular spangle has a visible zinc crystal pattern, while zero spangle provides a smoother and more uniform surface for painting and decorative applications.

Q2．What surface treatments are available?

Chromated, oiled, passivated, and anti-fingerprint treatments are available.

Q3．Can the coil be supplied in narrow strip widths?

Yes. The material can be slit from the master coil into custom widths as required.

Q4．Is this product suitable for furniture manufacturing?

Yes. The combination of corrosion resistance, formability, and surface quality makes it widely used for furniture and cabinet production.

Q5．What zinc coating range is available?

The standard range for this product is 60–275g/m², depending on application requirements.
