EN10147 Zero Spangle Hot Dipped Galvanized Steel Strip with Passivated and Oiled Surface

1．Product Overview

EN10147 hot dipped galvanized steel strip is designed for corrosion-resistant industrial processing and structural applications. The strip is produced using continuous hot dip galvanizing technology to provide stable zinc coating adhesion, consistent surface quality, and reliable forming performance.

Zero spangle galvanized strip is commonly selected for painting, roll forming, appliance panels, welded tubes, and applications requiring a smooth surface appearance.

Passivated and oiled surface treatment helps reduce white rust risk during transportation and long-term storage.

2．Technical Solution

• The galvanized strip is manufactured according to ASTM A653, JIS G3302, and EN10147 standards using commercial forming grades including SGCC, DX51D+Z, DX52D+Z, and DX53D+Z.
• The zinc coating range from 40–450g/m² supports both indoor and outdoor corrosion protection requirements.
• Zero spangle finish provides improved surface uniformity for downstream coating, painting, and decorative processing.
• Passivation and oil coating improve export transportation stability under humid storage conditions.
