508mm / 610mm ID Hot Dipped Galvanized Steel Coils 600–1500mm Width for

1．Product Overview

508mm / 610mm ID hot dipped galvanized steel coils are used for construction, automobile parts, machinery fabrication, container production, shipbuilding, roofing, wall cladding, outdoor structures, and general steel processing applications.

The product is produced by hot dipped galvanizing, with zinc coating from 40g/m² to 450g/m². The galvanized coating provides surface protection for applications requiring corrosion resistance, forming performance, and long-distance shipment stability.

2．Technical Solution

The steel coil is processed through hot dipped galvanizing, where the steel substrate is coated with zinc to improve corrosion resistance and surface durability.

Surface treatment options include chromated, oiled, bright, and dry finish. Chromated and oiled surfaces are suitable for anti-rust protection during storage and shipment. Bright and dry surfaces can be selected according to downstream processing and appearance requirements.

Regular spangle and zero spangle options support different surface appearance needs for construction panels, machinery parts, containers, and industrial fabrication.

4．Application

This product is suitable for construction roofing, wall cladding, structural fabrication, automotive parts, machinery components, containers, shipbuilding parts, fences, outdoor panels, and industrial processing.

It can be used in applications requiring galvanized steel coils with corrosion resistance, controlled zinc coating, regular or zero spangle surface, and standard coil ID for downstream forming or slitting lines.

5．Processing

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

Standard export seaworthy packing protects the coil during container shipment and long-distance transportation. Coil ID options of 508mm and 610mm support common processing equipment and coil handling systems.

6．Advantages

• Zinc coating from 40g/m² to 450g/m² supports different corrosion resistance requirements.
• 0.12–4.0mm thickness range covers light gauge sheet processing and heavier fabrication applications.
• 600–1500mm width range supports roofing, cladding, machinery, container, and industrial use.
• 508mm and 610mm coil ID options match common coil processing lines.
• Regular and zero spangle surfaces support different appearance and downstream coating requirements.
• Chromated, oiled, bright, and dry surface options provide flexibility for storage, shipment, and fabrication.

7．How to Choose

• Choose 508mm coil ID when the processing line requires standard smaller inner diameter coils.
• Choose 610mm coil ID for equipment or handling systems designed for larger inner diameter coils.
• Choose higher zinc coating when stronger corrosion resistance is required.
• Choose oiled or chromated surface for improved storage and shipment protection.
• Choose zero spangle when a smoother surface appearance is required.
• Choose regular spangle when visible galvanized appearance is acceptable.
• Confirm thickness, width, coil ID, coil weight, zinc coating, surface treatment, spangle type, and packing method before production.
