Tube bending and rolling

In-house tube bending for complex geometries such as oval tube and D-shaped tube

Fixed Radius tube bending for tight bends

We can achieve the following fixed radius bends, provided the wall thickness of the tube is sufficient (a wall thickness of 2mm or more is recommended to reduce necking):

Can't see the Centreline Radius (CLR) you require?

If the CLR you need is 2.5x larger than the diameter of the plane that needs bending then fixed-radius bend tooling can be custom-made for your job. Contact us about new tooling.

If the CLR is less than 2.5x the tube's diameter then mandrel bending will be more appropriate. Mandrel bending produces high-quality tight bends with reduced deformation, and is ideal for high-volume bend work. Making new mandrel tooling can be a lengthy process — contact us about mandrel bending.

90º bends, connectors and end caps

High-quality stainless steel elbow / corner joints are available for some of our popular tube profiles.

Please note that these connectors use a tight interference fit so they are likely to require some fabrication. You may need to grind / fettle the connector in some instances, or use a soft hammer to fit the connectors. Most fabricators weld the connectors to ensure a fit that is both watertight and seamless in appearance.

Ring Rolling tube for continuous bends

Using a triple roller tube bending machine, we can make sweeping curves in several of our tube profiles, allowing for a smooth, consistent radius for applications such as curved handrails or hoops. Also known as section rolling or three-roll bending, our fabricators use shaped rollers designed for several of our profiles:

What is the maximum length of tube that can be rolled? 

We are not limited to the length for tube that we can bend, which is ideal for applications such as handrail. However most of our oval tubing is formed in 5.8m lengths, so you may be limited to this length.

Is it possible to bend tube horizontally and vertically at the same time, for staircases and boat rails? 

We are able to bend on both planes to allow for a slight incline along a length of handrail. However this is a gradual transition between the two planes; we cannot offer helical bending for spiral staircases. Our fabricators can inform you of what is possible.

Can other tube profiles and tube sizes be rolled if they are not listed? 

Although we use specifically designed tooling to bend the oval and D-shaped tubing listed, our fabricators are sometimes able to bend alternative sizes and shapes of tubes using existing tooling. We are also able to explore new tooling options for your application, so please speak to our team about your requirements.

Press bending tubes and other tube bending options

At Timeless Tube we find solutions for custom tube requirements, which sometimes means trialling fabrication techniques that we don't typically use.

If the dimensions allow for it, thin tubing can be folded.

When tight bends are not possible without new tooling and you only require a small quantity of tight bends, our fabricators can mitre-cut the tubing and join the cuts with welding.

Mitre-joining: an alternative to tube bending

When tight bends are not possible without new tooling, our tube fabricators can alternatively mitre-cut the tubing then join the cuts with welding at the required angles. This is ideal for projects that do not require a high volume of angled bends, such as bespoke lift interior rails, balconies and grab handles for custom-designed yachts.
