Frequently Asked Questions
What is stainless steel oval tube?
Stainless steel oval tube has an elliptical cross-section with a major and minor axis. Produced by cold-drawing or forming from round tube, it is used in furniture, automotive exhaust tips, handrails, and architectural applications where a distinctive oval profile is required.
What sizes are available for stainless steel oval tube?
Common oval tube dimensions range from 9×18 mm to 100×150 mm (major×minor axis) with wall thickness 0.5 mm to 3.0 mm. Custom dimensions and non-standard aspect ratios up to 3:1 are available.
What grades and finishes are available for oval stainless steel tube?
Available in grades 201, 304, 304L, 316, and 316L. Surface finishes include 2B, No. 4 brushed, No. 8 mirror, BA, and PVD coloured coatings. All standard polishing processes are compatible with the smooth oval surface profile.
What are the main applications for oval stainless steel tube?
Oval stainless steel tube is used in car exhaust tips and body trim, furniture legs and frames, architectural railings, bicycle frames, ergonomic handrail inserts, and design applications where an oval profile provides visual distinction or improved ergonomics versus round tube.
Can stainless steel oval tube be bent without distortion?
Oval tube can be bent along both the major and minor axes. A minimum bend radius of ≥ 4× the major axis width is recommended to prevent profile distortion. Mandrel bending is strongly recommended to maintain the oval cross-section shape through the bend zone.
