APPLICATIONS FOR D-SHAPED TUBE
- Kick rails
- Metal stair nosing
With a smooth top, flat section and incredible lateral strength, this ingenious design prevents water ingress and it’s easy to install. Ideal for handrail in public buildings and on marine craft.
Our unique D-shaped profile been cleverly developed with ease of installation in mind. Ideal for public buildings, private yachts and cruise liners, its distinctive ridged design boasts tremendous strength. It has a flat and secure base which is easy to apply to bulwarks, brickwork and balustrades – including glass.
D-shaped tube is predominantly used as handrail. It is easy for fabricators or fitters to weld square-cut balusters directly to the underside of the tubing. Or you can attach a glazing channel to it either through welding or by attaching threaded inserts to the underside.
Its lateral strength means it makes a great replacement for traditional bulwark capping or handrail on larger boats and cruise liners. The unique shape not only aids installation but it will also stop water ingress to the underside. This makes it more corrosion-resistant, as it reduces pitting and water collecting underneath.
For centuries, teak wood has been used aboard sea-faring craft, but teak is becoming increasingly limited in availability and increasing expensive. When made from ‘marine grade’ 316L stainless steel, the D-shaped profile makes a wonderful alternative to teak bulwark capping. It has become the selection of choice for boat owners and shipbuilders alike since it requires no maintenance and will always look new. However, if a traditional teak wood-effect is desired, we can apply a special coating to the metal (this can be applied to aluminium and stainless steel tubing).
Most often, we make the D-shaped tube profile from stainless steel and aluminium due to the applications that it is used for, although it can be made from brass, copper and cupronickel.
We offer a joining system for some of our most popular-sized D-shaped tubes, which enables you to produce handrail and balustrades with uncompromising, seamless joins. Find out more.
The image above shows how dimensions are detailed (for example, 34mm x 12mm x 1.5mm).Below is a table of the available stainless steel tube sizes that we have in our existing range for this shape of tube. Please note that stainless steel and aluminium 5083 oval tube profiles are sold in lengths of 5.8m (the manufacturing process reduces the standard 6m length by 0.2 metres).
Can’t see the tube sizes you need? Contact us to discuss your project requirements – we may be able to fabricate some custom-made sized tubing. Or download our sizing PDF, which contains sizing information for existing aluminium and brass tubing too, as well as all stainless steel sizes.
Upon request, we will be able to find out wall thickness tolerances from our metal suppliers. Typically the tolerance levels of wall thickness are extremely minimal and any small variations in thickness do not affect further fabrication or the end application. However, it is important to let us know if the tolerance is critical to the application before you place an order. For example, if the shaped tubing component needs to go inside another component, or if the tubing has to house a component, any variation in wall thickness could be critical. Ask us about tolerances.
