Corrosion-resistant And Aesthetic Tubing Solutions
Stainless steel oval pipes offer corrosion resistance and aesthetic appeal for architectural, marine, and industrial applications.
D-shaped tube
Shaped tube railings, including oval, D-shaped, and radius square profiles, enhance aesthetics and ergonomics for handrails in various applications.
Oval tube handrails, available in sizes like 47 x 25 x 1.5mm and 61 x 37 x 2mm, and D-shaped tube handrails, typically in 50 x 18 x 1.5mm or 65 x 28 x 2mm, are crafted from stainless steel for a sophisticated appearance and ergonomic grip. The D-shaped profile, with its curved topside, is designed for comfortable and secure grasping, outperforming standard round tubes in both function and style.
Radius square tube, with gently contoured corners, serves as an elegant alternative for grab rails and boat railings on super yachts and tenders. These stainless steel profiles, compliant with standards like ASTM A554 and EN10219-1, offer corrosion resistance and durability. Surface finishes such as polished or mirror enhance their aesthetic appeal, making them ideal for architectural, marine, and structural applications.
Shaped tube railings combine style, comfort, and durability, providing premium solutions for modern handrail and railing systems.
Stainless Steel Oval Pipes are specialized stainless steel tubes with an elliptical cross-section, designed for both functional and decorative applications. Compliant with standards like ASTM A554, A269, and A312, these pipes are typically made from austenitic grades such as 304 and 316, offering tensile strengths of 485–515 MPa and exceptional corrosion resistance. They are ideal for architectural design, marine applications, and automotive exhaust systems.
Produced through seamless or welded processes like TIG or laser welding, Stainless Steel Oval Pipes are available in sizes with outer diameters from 9.5 mm to 108 mm and wall thicknesses from 0.5 to 2.0 mm. Surface finishes, including polished, brushed, or mirror finishes, enhance their aesthetic appeal and corrosion resistance, making them suitable for food processing equipment and furniture manufacturing. Standard lengths range from 5.8 to 12 meters, with custom lengths available.
Rigorous testing, including tensile, flattening, and corrosion tests, ensures compliance with standards. The high chromium (16–20%) and molybdenum (2–3% in 316 grades) content provides superior resistance to pitting and crevice corrosion, ideal for chemical processing and marine environments. Their oval shape offers better maneuverability in tight spaces compared to round pipes, supporting applications like railings and structural supports.
Compared to round stainless steel pipes, Stainless Steel Oval Pipes provide enhanced aesthetic appeal and directional strength, though they may have slightly lower pressure resistance. Their versatility, biocompatibility, and low maintenance make them a preferred choice for hygienic and high-corrosion environments, offering a balance of performance and cost-effectiveness.
Stainless Steel Oval Pipes address challenges like corrosion, space constraints, and aesthetic requirements, delivering reliable, high-performance solutions for diverse industrial and decorative applications.
Stainless steel and aluminium oval tube profiles are crafted to precise sizes and tolerances, ideal for specialized applications requiring unique shapes.
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.
Wall thickness tolerances are typically minimal, with variations that do not impact further fabrication or end use in most cases. However, for applications where precise tolerances are critical—such as when tubes must fit inside or house other components—customers should specify requirements before ordering. Compliance with standards like ASTM A554 and rigorous testing ensures durability and performance in demanding environments, such as construction or marine applications.
The oval tube profiles offer customized sizing and high precision, delivering aesthetic and functional solutions for specialized industrial needs.

In order to solve the cumbersome and difficult to remember stainless steel grades, improve the practicability of the brand representation, and the contrast with the international standard grades, China has formulated the "Universal Code System for Steel and Alloy Grades", such as 06Cr19Ni10, corresponding to 304. Different grades of stainless steel have different ingredients, but they all have a national standard. The standards of each country are also different.
