Stainless Steel Square Tube&Pipe

1. What is a Stainless Steel Square Pipe?

A stainless steel square pipe is a hollow square-section tube made from stainless steel. Due to its unique geometric shape and excellent performance, it is widely used in architectural decoration, furniture manufacturing, mechanical structures, and industrial engineering. Compared to round pipes, square pipes offer higher moment of inertia and section modulus when subjected to bending moments in specific directions, demonstrating superior bending resistance. Its main parameters include material grade, side length, wall thickness, and length.

2. Classification of Stainless Steel Square Pipes

• By Application:
  • Decorative stainless steel square pipes
  • Structural stainless steel square pipes
  • Industrial stainless steel square pipes
• By Manufacturing Process:
  • Seamless Square Pipes: Produced through hot rolling, extrusion, or cold drawing processes, offering high integrity and pressure-bearing capacity.
  • Welded Square Pipes: Formed by shaping stainless steel coils or plates and then welding (typically TIG welding), featuring high production efficiency and relatively lower cost.
• By Material Grade:
  • 201 Stainless Steel Square Pipe
  • 304 Stainless Steel Square Pipe
  • 316L Stainless Steel Square Pipe Different materials correspond to varying levels of corrosion resistance and suitability for different environments.

3. Specifications of Stainless Steel Square Pipes

• Material Grades: Common grades include 201, 304, and 316L austenitic stainless steels. 201 offers economic practicality, 304 provides excellent overall performance, and 316L boasts superior corrosion resistance.
• Side Lengths: 10×10, 15×15, 19×19, 20×20, 22×22, 25×25, 30×30, 38×38, 40×40, 50×50, 60×60, 80×80, 100×100 mm, 기타.
• 벽 두께: 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 mm, 기타.
• 길이: Standard length is typically 6 meters per piece, with non-standard lengths available upon customer request.
• Surface Finish/Color: Common finishes include 8K mirror, 브러시 (snow sand, dry sand, oil sand, 등.), and sandblasted. Through vacuum titanium plating, various decorative colors such as titanium gold, 로즈 골드, 샴페인 골드, 블랙 티타늄, and zirconium gold are available to meet diverse aesthetic requirements.

4. How is a Stainless Steel Square Pipe Manufactured?

• Welded Square Pipe Production Process: 원자재 (코일/판재) → 언코일링 → 레벨링 → 성형 (스퀘어 롤 포밍) → TIG 용접 → 냉각 → 용접 이음 매끄럽게 다듬기 → 길이로 절단 → 스트레이트닝 → 표면 처리 (브러싱, 폴리싱, 등.) → 검사 → 포장 → 출하
• 무이음 스퀘어 파이프 생산 공정: 원형 블리켓 → 가열 → 피어싱 → 열간 압연 (또는 압출) 원형 튜브로 → 재가열 → 사이징 (다이에 의한 압출 또는 압연) 정사각형으로 → 냉각 → 스트레이트닝 → 절단 → 표면 처리 → 검사 → 포장 → 창고 보관 (참고: 무이음 스퀘어 파이프는 상대적으로 드물며, 종종 원형 파이프에서 가공되거나 직접 압출됩니다.)

5. Key Features of Stainless Steel Square Pipes

• Structural Advantages: The square cross-section provides better bending resistance compared to round pipes of the same weight, making it ideal for frames, supports, and applications requiring resistance to bending moments.
• Excellent Aesthetics: Sharp edges and clean lines offer a modern, 세련된 외관, widely used in building facades, interior partitions, door and window frames, and furniture legs.
• Ease of Fabrication: Flat surfaces facilitate welding, connection, and installation, especially suitable for modular design and assembly.
• Material Properties: Inherits the benefits of stainless steel, including corrosion resistance, high-temperature resistance, anti-rust properties, 긴 서비스 수명, and easy cleaning and maintenance.

6. Applications of Stainless Steel Square Pipes Stainless steel square pipes are a vital material in construction and industry, with extensive applications:

• 건축 장식: Curtain wall frameworks, door and window frames, staircase handrail posts, balcony railings, interior partitions, elevator trims, 기타.
• Furniture Manufacturing: Table and chair frames, coffee table legs, bookshelves, display racks, storage shelves, 기타.
• Industrial Use: Machinery frames, conveyor line supports, workbenches, protective barriers, chemical pipeline supports, 기타.
• Municipal Engineering: Public facilities (e.g., bus shelters, bicycle racks), landscape features, fences, 기타.
