Product Specification

Regular or Big Spangle Hot Dipped Galvanized Steel Strip with Passivated and Oiled Surface

1．Product Overview

Hot dipped galvanized steel strip is designed for pipe making, construction components, roofing accessories, home appliance parts, automotive corrosion-resistant parts, and general metal fabrication.

The product uses cold rolled or hot rolled steel substrate with a continuous hot dip zinc coating process. The zinc layer provides corrosion protection, while passivated and oiled surface treatment helps improve storage protection and processing performance.

Regular spangle and big spangle surfaces are available for projects requiring visible galvanized surface appearance.

2．Technical Solution

The steel strip is coated by hot dip galvanizing to form a protective zinc layer on the steel surface.

The available zinc coating range is 40–450g/m², supporting different corrosion protection requirements for indoor, outdoor, and fabrication applications.

Surface treatment options include passivated, oiled, and anti-fingerprint. Passivation helps reduce white rust during storage, while oiling supports better protection during transportation and further processing.

4．Application

This galvanized steel strip is suitable for welded pipe production, greenhouse pipe, heating pipe, construction profiles, roof accessories, light steel framing, 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 protection, 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, transport, and processing requirements.
• Standard export packing supports container shipment and long-distance transportation.

6．Advantages

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

7．How to Choose

• Choose regular or big spangle when visible galvanized appearance is required.
• Choose minimized or zero spangle when a smoother surface is preferred 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 transport protection.
• Confirm strip width, thickness, coil ID, coil weight, zinc coating, and final processing method before production.
