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.

Common Grades of Stainless Steel Square Tubes

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 of Stainless Steel Square Tubes

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.

Product Standards

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

Applications of Stainless Steel Square Tubes

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).

Advantages of Stainless Steel Square Tubes

  • 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.

Related Products

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.
