Continuous Cold-Rolled Screw Flights
Product Overview
Our continuous cold-rolled screw flights are manufactured using advanced rolling equipment that ensures uniform thickness, stable pitch, and high forming accuracy. Compared with sectional or pressed flights, continuous cold-rolled flights offer higher strength, smoother operation, and better dimensional consistency, making them suitable for long-length and high-speed conveying systems.
We specialize in continuous flights made from SPHC carbon steel, providing stable performance for agricultural augers, grain handling equipment, biomass conveyors, and industrial screw systems. Custom sizes and OEM production are fully supported.
SPHC carbon steel
Within the scope of meeting the following table, customized production according to customer requirements.
| Inner hole plate thickness (mm) |
Minimum inner diameter (mm) |
Maximum outer diameter (mm) |
Maximum radius difference (mm) |
Pitch outer diameter ratio | Outer diameter inner diameter ratio |
| 3.0 | 20 | 500 | 165 | 0.6-1.3 | 4.0 |
| 3.5 | 20 | 500 | 165 | 0.6-1.3 | 4.0 |
| 4.5 | 28 | 500 | 165 | 0.75-1.3 | 4.0 |
| 5.0 | 28 | 500 | 165 | 0.8-1.3 | 4.0 |
| 6.0 | 40 | 500 | 165 | 0.8-1.2 | 4.0 |
Emarks:
1. If the inner diameter of the customized specification is required to be within the range of the minimum inner diameter + 5mm, the maximum outer diameter of the specification cannot exceed 3 times the inner diameter.
2. For orders whose plate thickness is not within the range of the above table, due to material preparation reasons, the product weight for one order must be greater than 15 tons.
3. For other situations, please contact our company for detailed consultation, the hotline 400 086 6258.
Key Advantages
1. Continuous Forming (No Welding Joints)
Stronger structure, better balance, and reduced risk of deformation.
2. High Dimensional Consistency
Accurate OD, pitch, and thickness through controlled rolling technology.
3. Improved Steel Strength via Cold Working
Cold-rolling enhances density and mechanical properties of SPHC steel.
4. Cost-Effective and Reliable
SPHC carbon steel offers good forming ability and stable performance in most industrial applications.
5. Full OEM Capability
Custom OD/ID/pitch/thickness, drawing-based production, and global shipment.
Applications
Production Process
Using automated cold-rolling lines, steel strip is continuously formed under pressure to achieve the required spiral geometry. This ensures smooth edges, uniform thickness, precise pitch, and excellent structural stability, offering longer service life and better conveying efficiency than segmented flights.
