What Is a Carbon Steel Flat Oval Tube?
Carbon steel flat oval tubes are cold-rolled and welded tubes.
Due to their compact design, these tubes serve as excellent alternatives to larger round tubing options.
Their versatility and straightforward installation make them particularly well-suited for complex
structures such as railings and balustrades. Additionally, the rounded edges of these tubes simplify
maintenance, as any accumulated dirt or debris can be easily wiped or washed away from their contoured
profile. For round profile cold-formed tubing, see our Cold Drawn Seamless Mechanical Tubing and Hot Rolled Steel Pipes Seamless Tube range.
Wide-scale Application of Carbon Steel Flat Oval Tube: Flat oval tubes are being used across several
sectors, which is an advantage if you're running a multi-industry enterprise. Residential property
developers and designers use these tubes to make home furniture, decorations, staircases, and fences.
Moreover, they are being used in shopping carts, trolleys, displays, and commercial property
construction in general.
The automotive industry also utilizes steel flat oval tubes. These metal solutions are an essential
component of car engines and exhausts. Cables and electronics can neatly pass through the tubes' hollow
interior. Furthermore, the flat side of the tube can serve as a mounting platform for vehicle
components.
Furthermore, the industry welcomes thorough inspection conducted by a third-party inspection agency with
extensive experience and legal certification. This inspection scrutinizes essential parameters at all
stages of production, ensuring the superior quality of Carbon Steel Flat Oval Tube. The comprehensive
visual inspection by the third-party agency further reinforces the manufacturer's commitment to
delivering top-notch products.

Elliptical Steel Tubing Manufacturing Process
Carbon steel flat oval and elliptical tubes are manufactured through a cold-rolling and welding process. Steel strip or coil is fed through a series of forming rolls that progressively shape it into a circular tube, which is then welded longitudinally (typically by ERW or high-frequency induction welding) before passing through additional in-line shaping and sizing rolls that reform the round profile into the final oval, flat oval, or elliptical cross-section. The tube may then undergo annealing or stress-relief treatment depending on the required mechanical properties and finish.
Oval Steel Pipe Available Lengths

Oval Steel Tubing Sizes – Weight Calculation Formula
The approximate weight per meter of an oval or flat oval steel tube can be calculated using the cross-sectional area of the tube wall multiplied by the material density (7.85 kg/dm³ for carbon steel). [INSERT: Provide the exact formula your team uses, e.g., Weight (kg/m) = [(2 x (Major Axis + Minor Axis − 2 x Wall Thickness)) x Wall Thickness] x 0.00785, or link to the existing Steel Weight Calculator tool for live calculation.]

Frequently Asked Questions – Oval Steel Tube & Elliptical Tube
What is an oval steel tube?
An oval steel tube is a cold-rolled and welded steel tube formed into an oval cross-section rather than a round one. It offers a compact, space-efficient profile that serves as an alternative to round tubing in applications such as railings, balustrades, furniture, and automotive components, while its rounded edges make it easier to clean and maintain than sharp-cornered profiles.
What is the difference between an oval tube and an elliptical tube?
Oval tube and elliptical tube are often used interchangeably in the steel industry, both referring to a non-circular, rounded cross-section tube. In technical terms, an elliptical tube follows a true mathematical ellipse shape, while an oval tube may have a slightly flattened or asymmetric curve. In practice, both are manufactured using the same cold-rolling and welding process and serve similar structural and decorative applications.
What is a flat oval tube used for?
A flat oval tube is commonly used in railings, balustrades, staircases, fencing, home and commercial furniture, retail display fixtures, shopping carts, and automotive components such as engine and exhaust parts. Its flat side provides a convenient mounting platform for hardware or panels, while its hollow interior allows cables or wiring to pass through neatly.
What sizes are available in oval steel tube?
Oval and elliptical steel tube is typically available in sizes ranging from approximately 12mm to 88mm on the major axis and 15mm to 88mm on the minor axis, with wall thicknesses from 0.5mm to 4mm. Flat oval tube is available in a separate size range from 11mm to 40mm x 22mm x 90mm with wall thickness from 0.6mm to 1.7mm. Custom sizes outside these ranges can be manufactured on request.
What materials are used to make oval steel tubing?
Oval steel tubing is commonly manufactured from carbon steel grades such as SPCC, Q195, Q215, and Q345, selected based on the required strength, formability, and application. SPCC is typically used for cold-formed decorative and furniture applications, while Q195 through Q345 offer increasing strength for structural and load-bearing uses.
What standard lengths does elliptical steel pipe come in?
Elliptical steel pipe and oval tube are commonly stocked in standard lengths of 3m, 5.8m, 6m, and 12m. Custom cut lengths are available on request to match specific project or fabrication requirements.
What is an oblong tube?
An oblong tube is another term sometimes used to describe a flat oval or elongated oval-section tube, similar in shape to a flat oval tube but generally referring to a more elongated, rectangular-like curve rather than a symmetric oval. The terms oblong, flat oval, and elliptical are often used loosely and interchangeably depending on regional or industry convention, so it's best to confirm exact dimensions when specifying.
Is oval steel tube the same as round tube that's been flattened?
No. Oval steel tube is manufactured directly through a cold-rolling and welding process specifically designed to produce an oval or elliptical cross-section from flat strip or coil, rather than starting as a round tube and being flattened afterward. This direct-forming process maintains more consistent wall thickness and structural integrity across the tube's profile compared to post-formed flattened round tube.
What industries commonly use flat sided oval tube?
Flat sided oval tube is widely used in architectural and construction applications such as railings and balustrades, in furniture and interior design for frames and supports, in retail for shopping carts, trolleys, and display fixtures, and in the automotive industry for engine components, exhaust systems, and structural mounting platforms.
