Stainless steel rectangular pipes are among the most versatile and reliable materials used across various industries today. Known for their strength, durability, and clean appearance, these pipes are essential for construction, fabrication, and fluid transport systems. If you’re looking for a trusted Stainless Steel Rectangular Pipe Supplier, it’s vital to choose one that offers superior quality, precision, and consistency.
This blog explores everything you need to know about stainless steel rectangular pipes, their specifications, applications, advantages, and what makes a reliable supplier stand out in the market.
What Are Stainless Steel Rectangular Pipes?
A stainless steel rectangular pipe is a hollow section made from stainless steel, featuring a rectangular cross-section. It is manufactured using either seamless or welded processes and is widely used where both aesthetic appeal and strength are required.
The most common grades include SS 304, SS 316, SS 202, and SS 310, each offering distinct properties suitable for specific environments.
Unlike round pipes, rectangular pipes provide more surface area, making them ideal for structural and architectural purposes. They are resistant to rust, oxidation, and high temperatures—making them perfect for harsh industrial applications.
Key Features of Stainless Steel Rectangular Pipes
- Excellent Corrosion Resistance:
Stainless steel offers superior resistance against corrosion, rust, and chemical exposure, ensuring long-lasting performance in various conditions. - High Strength-to-Weight Ratio:
Despite being lightweight, stainless steel rectangular pipes provide remarkable strength, making them suitable for load-bearing structures. - Smooth Surface Finish:
The polished surface enhances visual appeal and reduces friction loss in fluid transport systems. - Temperature Resistance:
These pipes can withstand high and low temperatures, maintaining structural integrity even in extreme environments. - Easy Fabrication:
Stainless steel is easy to cut, weld, and form, which makes these pipes ideal for custom fabrication and design flexibility.
Grades and Specifications
Stainless steel rectangular pipes come in multiple grades, with the following being the most common:
| Grade | Composition Highlights | Applications |
|---|---|---|
| SS 304 | Chromium (18%) and Nickel (8%) | General construction, food processing, and furniture |
| SS 316 | Added Molybdenum for corrosion resistance | Marine, chemical, and pharmaceutical industries |
| SS 310 | High chromium and nickel | High-temperature applications |
| SS 202 | Cost-effective alternative | Household equipment, light structures |
Standard Specifications:
- Standards: ASTM A554, ASTM A312, ASTM A249
- Sizes: 10mm x 20mm to 250mm x 400mm
- Thickness: 0.5mm to 20mm

Manufacturing Process of Stainless Steel Rectangular Pipes
- Raw Material Selection:
Premium stainless steel billets or coils are chosen based on the required grade. - Forming:
The raw material is rolled into a rectangular shape using advanced forming mills. - Welding (for welded pipes):
Edges are joined using TIG or laser welding for precision and smooth seams. - Heat Treatment:
Pipes are heat-treated to relieve internal stress and enhance strength. - Pickling and Polishing:
The surface undergoes chemical cleaning and polishing to remove impurities and improve finish. - Inspection and Testing:
Each pipe undergoes non-destructive testing such as hydrostatic testing, ultrasonic inspection, and dimensional checks. - Packaging:
Pipes are wrapped in protective material and bundled for safe transportation.
Applications of Stainless Steel Rectangular Pipes
Stainless steel rectangular pipes are versatile and find applications across numerous industries due to their strength, durability, and resistance properties.
1. Construction and Architecture
Used in structural frameworks, railings, supports, and decorative elements for modern architecture due to their aesthetic finish and durability.
2. Automotive and Transport
Ideal for manufacturing exhaust systems, chassis, and frames that demand strength and resistance to high temperatures.
3. Chemical and Petrochemical Industries
Resistant to chemicals and corrosive substances, making them suitable for handling fluids and gases in harsh conditions.
