Spiral and helical bending are innovative processes that have become necessary in the world of construction and architecture. At Angle Ring, we have honed our expertise in this metal bending technique, offering a broad range of spiral bending machines to cater to diverse project needs across the globe. In this blog, we delve into the unique aspects of spiral and helical bending, exploring the capacities, applications, and showcasing our skills at Angle Ring.
Getting to the core of spiral bending
Spiral bending is a technique predominantly applied to plate, tube, and flat bar elements, particularly in the creation of spiralled staircases. At Angle Ring, we operate a range of specialised machines capable of delivering precise 3-dimensional bends in tube, sections, plate, and solid bar, all within tight tolerances.

Unique offerings at Angle Ring
What sets Angle Ring apart in with our spiral and helical bending services is our commitment to accuracy and innovation. As a result, over the years, we have expanded our service offerings to include the precise bending of heavy plate and structural sections into intricate 3D shapes or helical profiles. This has positioned our steelwork on a diverse array of major structural projects across the world!
Maximum bending capacities at Angle Ring:
- Channels up to 430×100 PFC
- RHS up to 300×100
- Beams to 406×140
- Plate to 200mm thick
- Tubes up to 914Ø
- Fabricated RHS up to 430x200mm
Our capabilities extend to spiralled flat bar applications, ranging from handrails and infill sections on staircases to strengthened stringers and fabricated hollow sections.
What can we bend?
The versatility of Angle Ring’s services is reflected in the wide range of profiles we can bend, including:
- Plate
- Tube
- Sections
- Solid Bar
- Flat Bar
- Channels
- Beams
To illustrate our expertise, we highlight a noteworthy project where we successfully curved over 600 pieces of steel for Wilkinson Eyre’s spiral staircase in London’s Wellcome Collection. This intricate project showcased our talent in utilising pressing, cold rolling, and bespoke processes to shape and twist large steel plates.
Sectors embracing Spiral & Helical bending
Primarily thriving in the architectural and construction sectors, spiral and helical bending find their niche due to the complexity of architectural drawings. The precision required in these applications ensures minimal sectional distortion, and as a result, it adds a touch of finesse to the final structures.
