Stainless steel square tubes are hollow, square-shaped structural components made from stainless steel, a corrosion-resistant alloy containing chromium (minimum 10.5%) and other elements like nickel, molybdenum, or titanium. Their square cross-section offers unique mechanical properties, making them ideal for both structural and decorative applications.

Different grades are formulated to meet specific requirements, such as corrosion resistance, strength, or cost-effectiveness. Here are the most widely used ones:
Grade | Key Components | Primary Characteristics | Typical Use Cases |
---|---|---|---|
304 | 18% Cr, 8% Ni | Excellent corrosion resistance, good weldability, moderate strength | Food processing, architecture, furniture |
316 | 16% Cr, 10% Ni, 2-3% Mo | Superior corrosion resistance (especially to saltwater), high-temperature tolerance | Marine equipment, chemical plants, medical devices |
201 | 17% Cr, 5% Ni, Mn | Lower cost, good formability, suitable for dry environments | Decorative structures, automotive parts |
430 | 17% Cr, no Ni | Magnetic, cost-effective, moderate corrosion resistance (prone to rust in humid conditions) | Appliances, indoor structural frames |
Specifications vary by size (side length and wall thickness) and finish, tailored to application needs:
- Side Length: Typically ranges from 10mm to 300mm (e.g., 20×20mm, 50×50mm, 100×100mm)
- Wall Thickness: 0.5mm to 10mm (thicker walls for high-load structural use)
- Length: Standard 6m, customizable up to 12m
- Finish:
- Mill finish: Basic, for non-decorative purposes
- Polished: Mirror-like (e.g., 2B, BA), for aesthetics
- Brushed: Matte texture, common in furniture
Stainless steel square tubes adhere to international standards to ensure quality and consistency:
Standard | Issuing Body | Key Focus |
---|---|---|
ASTM A554 | ASTM International | Welded stainless steel mechanical tubing |
EN 10217-7 | European Committee | Welded tubes for pressure purposes (stainless) |
JIS G3446 | Japanese Industrial Standards | Stainless steel square tubes |
GB/T 12771 | China National Standard | Welded stainless steel pipes |
Their versatility stems from a balance of strength, corrosion resistance, and aesthetics:
- Construction: Frame structures, handrails, facades, and support columns
- Industrial: Conveyor systems, chemical pipelines, and machinery frames
- Automotive: Exhaust systems, chassis components (due to high strength)
- Marine: Boat railings, hull supports (316 grade resists saltwater corrosion)
- Decorative: Furniture, staircases, and interior design elements
- Food & Medical: Sanitary pipes (304/316 grades, easy to clean and rust-free)
- Corrosion Resistance: Chromium forms a passive oxide layer, preventing rust (enhanced by molybdenum in 316)
- High Strength: Withstands heavy loads, suitable for structural use
- Durability: Long lifespan (up to 50+ years in ideal conditions) with minimal maintenance
- Aesthetic Appeal: Polished or brushed finishes add visual value in decorative applications
- Recyclability: 100% recyclable, aligning with sustainable practices
Other stainless steel tubular products often used alongside square tubes:
- Stainless Steel Round Tubes: For fluid transport (e.g., water, chemicals)
- Rectangular Tubes: Similar to square tubes but with unequal side lengths (e.g., 20×40mm), used in asymmetric structures
- Seamless Tubes: Higher strength than welded tubes, for high-pressure industrial use
- Square Pipes (Thick-Walled): Heavy-duty versions for bridge construction or heavy machinery
