Stainless Steel Rectangular Tube

High-Strength, Corrosion-Resistant Structural Profile for Industrial & Architectural Use


 

🔹 Product Overview

The 40×20mm stainless steel rectangular tube is a precision cold-formed hollow section widely used in construction, architectural decoration, furniture, handrails, and industrial equipment. With its sleek rectangular profile, excellent corrosion resistance, high strength-to-weight ratio, and modern aesthetic, this tube delivers both structural reliability and visual elegance.

Available in a range of wall thicknesses, grades, and surface finishes, the 40×20mm rectangular tube is ideal for applications requiring durability, clean appearance, and low maintenance in both indoor and outdoor environments.

Also known as: Rectangular Hollow Section (RHS), stainless steel flat tube, structural stainless tube

🔹 Features & Benefits

Featureفائدة

🔹 Manufacturing Process

  1. Raw Material: High-quality cold-rolled stainless steel coil (SUS304/316)
  2. Forming: Precision roll forming into rectangular shape
  3. Welding: High-frequency (HF) or TIG welding with full penetration
  4. Sizing & Calibration: Ensures exact 40×20mm dimensions and straightness
  5. Annealing: Stress-relief annealing for improved ductility and toughness
  6. Surface Treatment: Pickling, polishing, or brushing to achieve desired finish
  7. Straightening & Cutting: To standard or custom lengths
  8. Inspection & Testing: Dimensional, visual, and weld integrity checks
