Recoiled Steel Roll Forming Material Guide: Rewound Coil Specs & Uses
Recoiled Steel Roll Forming Material
1. Overview of Recoiled Steel in Roll Forming
Recoiled steel refers to material that has been unwound from a master coil and then rewound into a new coil, often after processes such as slitting, inspection, or correction of defects.
In roll forming, recoiled steel is commonly used when coils are split into smaller weights, adjusted for handling, or prepared for specific production requirements.
Compared to original mill coils, recoiled steel offers better handling flexibility and customized coil sizes, but may introduce variations in coil shape and tension.
2. Material Composition & Structure
Recoiled steel can be based on:
- Cold rolled steel
- Hot rolled steel
- Galvanized steel (GI)
- Galvalume / Aluzinc
- PPGI / PPGL
- Stainless steel
- Aluminum
Key Feature
- Material has been processed and rewound
- Coil tension and shape may differ from original
3. Available Coil Specifications
Thickness Range
- 0.3mm – 6.0mm
Coil Width
- 20mm – 1500mm (depending on slitting)
Coil Weight
- 500 kg – 10 tons (commonly reduced from master coil)
Coil ID / OD
- ID: 508mm / 610mm (can vary depending on recoiling setup)
- OD: up to 1500mm
Tolerance
- May vary slightly due to recoiling
- Coil shape and tension critical
4. Mechanical Properties
Same as base material:
- Yield Strength: 180 – 550 MPa
- Tensile Strength: 300 – 650 MPa
- Elongation: 15% – 35%
- Hardness: varies
5. Coating Types
Depends on original material:
- Zinc (GI)
- Aluminum-zinc (Galvalume)
- Paint coatings (PPGI / PPGL)
- Oil coating
- Passivation
6. Surface Finishes
- Metallic finish
- Painted finish
- Oiled or dry surface
- Passivated surface
7. Common Roll Forming Applications
- Roofing panels
- Structural profiles
- Purlins and channels
- Stud and track systems
- Custom roll formed products
8. Advantages of Recoiled Steel
- Easier handling (smaller coil sizes)
- Flexible coil weight options
- Suitable for smaller machines
- Reduced lifting and transport requirements
- Custom coil preparation
9. Disadvantages / Limitations
- Coil tension issues possible
- Risk of camber or shape defects
- Less consistency vs mill coil
- Potential surface damage during recoiling
- Requires quality inspection
10. Roll Forming Machine Considerations
Roll Tooling
- Standard tooling suitable
Feeding
- Pay attention to coil tension
- Proper decoiler setup required
Speed
- 10–40 m/min
Common Issues
- Coil telescoping
- Camber affecting alignment
- Uneven feeding
11. Common Problems in Production
- Coil set (memory from recoiling)
- Camber and curvature
- Strip wandering
- Uneven tension
- Surface damage
12. Pricing Guide
Typical global pricing:
- Base material: $600–$1800+ per ton
- Recoiling cost: $20–$80 per ton
Factors affecting price:
- Coil size reduction
- Material type
- Processing quality
- Supplier
13. Comparison with Other Materials
Recoiled Steel vs Master Coil
- Recoiled = processed and resized
- Master = original mill coil
Recoiled Steel vs Slit Coil
- Recoiled = rewound coil
- Slit = width processed
Recoiled Steel vs Narrow Coil
- Recoiled = weight adjusted
- Narrow = width reduced
14. Best Industries Using Recoiled Steel
- Roll forming production
- Steel fabrication
- Construction
- Manufacturing
- Automotive
15. How to Choose Recoiled Steel
Choose This Material When:
- Smaller coil weights required
- Limited lifting capacity
- Flexible handling needed
- Custom coil sizes required
Avoid When:
- High precision required
- High-speed production
- Consistent coil shape critical
