Stainless Steel Square Pipe & Tube

What are stainless steel square tubes used for?

Stainless steel square tubes are used in structural frameworks, handrails, furniture, architectural facades, food processing equipment, conveyor systems, and industrial supports where corrosion resistance is required alongside structural rigidity.

What sizes are available for stainless steel square tube?

TeCarve supplies square tubes from 10×10 mm to 300×300 mm with wall thickness 0.5 mm to 6 mm. Standard length is 6 m; cut-to-length is available. Grades 201, 304, and 316L in welded or seamless construction.

What surface finishes are available for stainless steel square tube?

Available finishes: No. 1 (hot rolled), 2B (cold rolled mill), No. 4 (brushed/satin), No. 8 (mirror), and PVD-coloured (gold, black, rose gold). Mirror finish square tube is widely used for decorative architectural and display applications.

What dimensional tolerances apply to stainless steel square tube?

Tolerances follow EN 10219 or ASTM A554: side-dimension tolerance ±0.5% or ±0.5 mm (whichever is greater), wall-thickness tolerance +15%/–10%, straightness ≤ 2 mm/m. Tighter precision tolerances are available for structural or precision machine applications.

Can custom corner radius stainless steel square tube be produced?

Yes. External corner radius typically ranges from 1.5t to 3t (where t = wall thickness). Sharp-corner square tube for architectural use and large-radius corner tube for sanitary or ergonomic applications are produced to customer specifications.
