Regular Spangle Hot Dipped Galvanized Steel Strip 30–1500mm with Z40–Z450 Zinc Coating

1．Product Overview

Regular spangle hot dipped galvanized steel strip is designed for welded pipe production, roofing accessories, construction profiles, home appliance parts, automotive components, and general fabrication.

The product is made by applying a zinc coating to steel strip through a continuous hot dip galvanizing process. The zinc layer provides corrosion protection, while regular spangle gives the strip a visible galvanized surface appearance suitable for general industrial and construction use.

2．Technical Solution

The steel strip uses SGCC or DX51D+Z substrate and is produced according to ASTM A653, JIS G3302, and EN 10346 standards.

The available zinc coating range is 40–450g/m², supporting different corrosion protection requirements. Surface treatment options include passivated, oiled, and anti-fingerprint. Passivation helps reduce white rust risk during storage, while oiling provides additional protection during transportation and processing.

4．Application

This galvanized steel strip is suitable for greenhouse pipes, gas pipes, heating pipes, construction roof accessories, roof grilles, light steel profiles, home appliance shells, kitchen utensils, automotive corrosion-resistant parts, storage equipment, and general metal processing.

It is commonly used where narrow-width galvanized steel requires corrosion resistance, stable coating quality, and good downstream forming performance.

5．Processing

• The strip can be supplied in slit coil form according to required width.
• It is suitable for roll forming, pipe welding, bending, stamping, cutting, and general fabrication.
• Surface treatment can be selected according to storage, transportation, and processing conditions.
• Standard export packing supports container shipment and long-distance transportation.

6．Advantages

• The 40–450g/m² zinc coating range supports different corrosion protection requirements.
• The 0.15–3.80mm thickness range covers light fabrication and heavier strip applications.
• The 30–1500mm width range supports slitting for pipe, profile, and component production.
• Regular, minimized, big, and zero spangle options meet different appearance requirements.
• Passivated and oiled surface treatment improves storage and transport protection.
• Coil ID 508mm / 610mm is suitable for standard uncoiling and processing equipment.

7．How to Choose

• Choose regular spangle when a standard galvanized appearance is required.
• Choose minimized or zero spangle when a smoother surface is needed for further coating or appearance-sensitive parts.
• Choose higher zinc coating levels for humid, outdoor, or more corrosive environments.
• Choose passivated and oiled surface for better storage and transportation protection.
• Confirm strip width, thickness, coil ID, coil weight, zinc coating, and final processing method before production.
