Spiral & Helical Bending

Working across many sectors, our Spiral Bending services at Angle Ring have been used on projects across the globe.

Typically used for plate and flat bar on spiralled staircases, we have developed our service offering to accurately bend heavy plate and structural sections into 3D shapes or helical profiles for architectural structures and feature steelwork on a wide variety of major structural projects.

We can offer spiralled flat bar on edge for handrail of infill sections on staircases, through to strengthened stringers or fabricated hollow sections.

Architectural drawings, no matter how complex, can be sent to us to work from in a variety of formats. Please see our Literature section to see our Technical sheets to assist in the specifying of your spiral bending project.

Stunning helical staircase shows Angle Ring skills

With over 600 pieces of curved steel Wilkinson Eyre’s spiral staircase in London’s Wellcome Collection was one of the most complex bending projects undertaken by Angle Ring.

The concept of the dynamic helical stair was to create a free-flowing form, travelling from floor to floor without any visually intrusive supports and the £1.1million steel and glass spiral staircase does this elegantly, linking the foyer space to first floor galleries, and second floor library.
