Twisted Square Tube

Timeless Tube has developed and engineered a method of forming a unique twisted square tube. This stunning twisted tube profile provides a mesmeric aesthetic that can create a beautiful visual effect.

With the current trend for stainless steel handrails and balustrade, the stainless steel twisted square tube is an exciting, innovative form for architects, fabricators and architectural metalworkers to work with. Inspired by traditional wrought iron work features, this new design is a striking alternative to standard round or square tube profiles.

Apart from its aesthetic qualities, the twisted profile offers impressive strength integrity. Compared to a conventional solid twisted bar, it provides a lighter and more cost effective solution. The formed shape improves the rigidity and deflection capabilities in comparison to round tubes of the same wall thickness and material grade.

Our twisted square tubes are sold with a choice of continuous twist or incremental twist. This allows you to achieve a variety of styles to suit the style of your project. Please contact us today to discuss your project requirements.

Typically manufactured in either stainless steel 316L or stainless steel 304, we can also form this tube profile in copper, brass, and bronze for more decorative tube applications. Speak to us today for more information on choosing the right metal for your project.

The twisted square tube profile is usually supplied in a bright polish finish. To quickly achieve a mirror finish apply further sisal polishing. Contact our friendly team for more information on the various finishes available.

To make our twisted square tube profiles, our manufacturing process reduces the length by 0.2 meters. As a result, our stainless steel twisted square tube profiles and aluminium 5083 oval tube profiles are supplied in lengths of 5.8 meters. Other metals are supplied in different tube sizes; the total is size reduced by 0.2 meters.

Staircases Spindles
Balustrades Balusters
Furniture Decoration


Stainless Steel 316l / 1.4404

All of our five tube products are available in premium quality stainless steel 316L. Also known as 1.4404 stainless steel, this marine grade stainless steel have fantastic qualities with a high resistance to corrosion. Perfect for exterior applications both structural and decorative, it is a strong and versatile material that is ideal for marine applications.

Stainless steel 304 / 1.4301

Any of our tube styles can be made using stainless steel 304. Sometimes referred to as 1.4301 stainless steel, this practical and versatile material provides ample strength while retaining a high degree of manipulability. This quality metal is suitable for structural and decorative purposes and lends itself to interior applications.

Aluminium 5083

Aluminium 5083 is a high quality premium grade aluminium that possesses immense strength coupled with excellent formability. This combination makes aluminium 5083 perfect for a wide range of applications. This material has a high value, but the additional attribute of being lighter in weight makes it desirable for specific projects.

Aluminium 6063

Aluminium 6063 is cost effective alternative for applications where strength and weight are key attributes. Although a lower grade material compared to aluminium 5083, it remains a practical and versatile metal that can be used to create our flat sided oval tubes, oval tubes and ornamental square tubes.

Copper / Brass / Bronze

Copper is a pure metal that is known for its strength, durability, resistance to corrosion and natural reddish brown colour.

Brass is an alloy consisting of copper and zinc, which increases its strength compared to pure copper and provides a lighter gold-like finish.

Bronze is also an alloy consisting primarily of copper that offers increased strength and more resistance to abrasion.

All of our tube products are available in these metals and are suitable for decorative applications due to their enhanced aesthetics.

Stainless Steel Tube Finishes

Our quality stainless steel tubes are available in different finishes depending on your project requirements. We can deliver your tubes with a mill finish or descaled finish that is ready for you to incorporate into your project.

Brushed or satin finishes offer a warmer tone to unfinished stainless steel and is effective in disguising blemishes or fingerprints.

Alternatively, you could opt for a bright polished finish which provides a stunning aesthetic with reflective qualities and can achieve a mirror finish with sisal polishing.
