We produce welded stainless steel oval tubing and elliptical tube in a wide range of sizes, with different diameters with multiple thicknesses including thin wall and thick wall, oval and elliptical tubing have two shapes, elliptic tubing and flat oval tubing, oval tubing can be bent in different angles, stainless steel oval tubing is easy to fabricate and weld using multiple welding methods.
Common stainless steel grades include 201, 304, 304l, 316, and 316L, compared to other metals, stainless steel is an ideal material for many applications due to its excellent properties, high strength, good corrosion as well as more finishes for selection, tubing is easier to fabricate and maintain, oval steel tubing is usually applied for construction, mechanical, ornamental and decorative purpose.

Surface Finishes Of Oval Steel Tubing and Elliptical Steel Tube
Oval tubing is manufactured using the TIG welding method, starting from a quality stainless steel strip, cold formed through a set of rollers, tubes can be in welded condition and also have a bright annealing finish.
There are various stainless steel finishes for Elliptical Tubing and Oval Tubing, mill finishes, or polishing finishes. Brush finish and hairline finish are often provided for tube surfaces to achieve a good bright appearance.
Polishing is an important process for decorative tubing, there are several grit levels for selecting and obtaining a good surface roughness.
- 120 grit
- 180 grit
- 320 grit
- 400 grit
- 600 grit
Oval Steel Tubing Weight Calculation
Oval Tubing Circumference = 2× 3.1415 × b + 4 × (a – b)
a = the long semi-axis (half of the long axis)
b = the short semi-axis (half of the short axis)
FORMULA: (Circumference/3.1415 – Wall thickness) x Wall thickness x 0.0031416 x Density
For example
304 Stainless Steel Oval Tubing
38 × 19 × 1.5 mm
The Circumference should be 97.69mm, it is from 2× 3.1415 × 9.5 + 4 × (19 – 9.5)
The weight should be (97.69/3.1415 – 1.5) x 1.5 x 0.0031416 x 7.93 in kg per meter.
