304 316L Stainless Steel Square Pipe 10x10 to 200x200mm 6m Length

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:

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:

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
