Flat-sided oval tube

Our flat-sided oval tube offers exceptional strength and integrity. It’s specially designed for easy installation and is an excellent choice for metal balustrades and railings. Flat-sided oval tubes also make space-efficient alternatives to round tubing, perfect for use in machinery or automotive applications.

  • Practical and elegant — ideal for architecture and infrastructure
  • Clean, rounded lines and a flat-sided profile provide impressive strength
  • Timeless’s strongest tube shape — (54% stronger than standard round tube equivalent in robust deflection tests)
  • Its flat side fixes securely – and easily – to other elements
  • Flattened shape lends itself well to a vast number of applications (especially inside machines, when space is compromised)
  • Sweeping arcs or tighter fixed radius bends available
  • An ideal profile for telescopic tubing – or for housing components or cables

Stainless steel, flat-sided oval tubes: available in over 45 different sizes and multiple wall thicknesses.

From 10.5×3.5×1.5mm to 195×85×3mm.

Super strong, stainless steel, flat-sided oval tubing.

Our stainless steel, flat-sided oval tubes are some of our strongest profiles. Our carefully controlled deflection tests have shown that our flat-sided oval tubing is up to 54% stronger than standard round steel tubing. Along with our radius square profile, these are some of the toughest metal tubes on the market and a highly advantageous option for all architects and designers.

Flat-sided tubing is easier to fabricate and maintain

You may have seen our flat-sided oval tubing in the handrail at the top of the iconic Tottenham Hotspur Stadium. These profiles have a flat side which makes them easy to secure to other elements, so they’re a popular choice in architectural designs. The rounded edge also offers simple maintenance, so flat-sided oval tubing is often used in the medical and manufacturing industries. Water and dirt washes easily from the contoured profile, so it’s simple to maintain and clean.

Stainless steel (INOX) and other metals

Flat-sided oval tubes are most commonly formed from stainless steel 304L and 316L. These grades are extremely durable and have high corrosion resistance, making them perfect for external fittings such as boat railings and metal handrails. For decorative or restorative applications, we can also create flat-sided oval tubing from copper, brass, bronze and aluminium.

Joiners available for connecting D-shaped tube

We offer a joining system for some of our most popular-sized D-shaped tubes. The stainless steel joiners enable you to produce handrail and balustrades with uncompromising, seamless joins. If we don’t yet make joiners in the size you require, speak to the team as we can custom-make sizes.

Sizes

Stainless steel and aluminium 5083 Flat-sided 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 in the table? Contact us about custom-sized tubing; we may able to fabricate a new size to meet your project requirements. Or download our brochure, which contains sizing information for existing aluminium and brass tubing too, as well as all stainless steel sizes.

Tolerances

If required, we can 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 tell us 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.

A space-saving solution for product designers and engineers

The slim profile of our flat-sided oval tube is becoming increasingly popular with design engineers, who are able to improve their product design by using this flattened shape. It is ideal for automotive applications such as exhausts and engines, which require a compact profile for clearance reasons. It can neatly house cabling and electronics. The flat side can be used to mount other components.

We offer this shape in a wide range of sizes, but if we do not make the tube in a size you require then please ask because we can customise our tooling to make new sizes. If you need a prototype or a small run of flat-sided tubing, our minimum order quantity is just 1 length.

Fabrication services for flat-sided oval tube

This unique profile is used across so many practical applications, making it popular with design engineers and product designers. We regularly manipulate flat-sided oval tubing for various applications on behalf of our clients, providing services such as flaring and welding. Our engineers can also bend sections of this oval tubing if you require – either by ‘rolling’ sweeping arcs into the formed tube, or by using tooling to produce tighter, ‘fixed radius’ bends.
