EN10147 Zero Spangle Hot Dipped Galvanized Steel Strip with Passivated and Oiled Surface for Pipe and Construction Applications

１．Product Overview

EN10147 zero spangle hot dipped galvanized steel strip is used for welded pipes, construction roof panels, roof grilles, home appliance shells, kitchen utensils, automotive corrosion-resistant parts, refrigeration processing, storage systems, and packaging applications.

The product is manufactured through hot dip galvanizing, with zinc coating protection and passivated or oiled surface treatment. Zero spangle surface is suitable for applications requiring smoother appearance, while regular and big spangle options can also be supplied according to project requirements.

２．Technical Solution

The steel strip is continuously coated with zinc through hot dip galvanizing to form a protective metallic layer on the steel surface.

Passivated and chromated treatment helps improve storage protection and reduce white rust risk during shipment. Oiled surface treatment supports temporary anti-rust protection and downstream processing.

The product can be supplied according to ASTM A653, JIS G3302, and EN10147 standards, with SGCC, SGCD, SGCE, SGCH, DX51D+Z, DX52D+Z, and DX53D+Z grade options.

３．Specifications

４．Application

This galvanized steel strip is suitable for greenhouse pipes, gas pipes, heating pipes, industrial and civil building roof panels, roof grilles, home appliance shells, kitchen utensils, automotive corrosion-resistant parts, food and material storage, transportation equipment, refrigeration processing, and packaging materials.

It is commonly used where narrow galvanized strip requires corrosion resistance, forming performance, and stable surface protection.

5．Processing

The product supports slitting, cutting, roll forming, bending, stamping, welding, profiling, and general fabrication.

Customized width, length, zinc coating, spangle type, surface treatment, coil ID, and packing method can be supplied according to production requirements.

６．Advantages

• 30–275g/m² zinc coating supports corrosion resistance for construction, pipe, appliance, and automotive applications.
• Zero spangle provides a smoother surface for applications requiring better appearance or further processing.
• Passivated and oiled surfaces improve storage and transportation protection.
• 30–630mm width range supports welded pipe, narrow strip, and structural component production.
• ASTM A653, JIS G3302, and EN10147 standards support export and industrial procurement requirements.
• 508mm coil ID and 1000–1500mm coil OD support common processing equipment.

７．How to Choose

• Choose zero spangle when smoother surface appearance is required.
• Choose regular or big spangle when traditional galvanized appearance is acceptable.
• Choose passivated or chromated surface for better storage protection.
• Choose oiled surface when temporary anti-rust protection is required.
• Choose higher zinc coating for outdoor, humid, or corrosion-sensitive environments.
• Confirm grade, thickness, width, zinc coating, spangle type, surface treatment, coil size, and packing method before production.
