Stainless Steel 304 Welded Round/Square Pipe is one of the most widely used piping solutions across industries for its exceptional corrosion resistance, high durability, and excellent formability. These pipes are made from AISI 304 stainless steel, the most popular austenitic stainless steel grade, and are available in both welded round pipe and welded square pipe variants. Offering superior strength and a flawless surface finish, SS 304 welded pipes are the first choice for industries ranging from construction and automotive to food processing and chemical plants.
Why Choose Stainless Steel 304 Welded Round/Square Pipe?
SS 304 welded pipes provide a perfect combination of affordability, strength, and corrosion resistance. They are manufactured by welding high-quality 304 stainless steel strips or plates, resulting in precise dimensions and a smooth internal surface. Available in both round welded pipe and square welded pipe configurations, these pipes are highly versatile and suitable for structural and fluid transport applications.
Key advantages include:
- Superior corrosion resistance in a wide range of environments.
- Excellent weldability and formability, making them easy to fabricate.
- Smooth surface finish for improved aesthetics and hygiene.
- Available in multiple sizes, wall thicknesses, and lengths.
- Cost-effective compared to seamless pipes while maintaining high performance.
Types of Stainless Steel 304 Welded Pipes
Stainless Steel 304 Welded Round Pipe
These are cylindrical pipes widely used for fluid transport, structural applications, and architectural projects. SS 304 round welded pipes offer uniform diameter, superior strength, and are available in various finishes like Mill Finish, Polished, Brushed, Satin, BA (Bright Annealed), and Mirror Finish.
Stainless Steel 304 Welded Square Pipe
Square welded pipes are extensively used for structural frameworks, railings, and architectural designs where a clean and modern look is desired. SS 304 welded square pipes provide high strength, excellent load-bearing capacity, and are available in Matt Finish, Hairline Finish, BA Finish, and Mirror Finish.
Popular Finishes of SS 304 Welded Pipes
Stainless Steel 304 welded round/square pipes come in a variety of finishes to suit different applications:
- Mill Finish – Standard as-produced finish, suitable for industrial use.
- Polished Finish – Provides improved aesthetics and easy-to-clean surfaces.
- Brushed / Satin Finish – Ideal for architectural and decorative applications.
- BA (Bright Annealed) Finish – Smooth, reflective finish with enhanced corrosion resistance.
- Mirror Finish – High-gloss reflective finish for premium architectural projects.
- Matte / Hairline Finish – Offers a subtle, linear appearance suitable for interiors.
Applications of Stainless Steel 304 Welded Round/Square Pipe
The versatility of SS 304 welded pipes makes them suitable for a wide range of industries and applications, including:
- Architecture and Construction – Structural frameworks, railings, handrails, curtain walls, and decorative elements.

Manufacturing Process of SS 304 Welded Pipes
- Stainless Steel 304 welded round/square pipes are produced using high-quality 304 stainless steel strips. The manufacturing process includes:
- Slitting and forming – Stainless steel strips are formed into round or square shapes.
- Welding – Advanced techniques such as TIG (Tungsten Inert Gas) welding are used for precise, strong, and clean welds.
- Heat treatment – Pipes are annealed to enhance strength and corrosion resistance.
- Surface finishing – Polishing, brushing, or mirror finishing is done to meet customer requirements.
- Quality testing – Pipes undergo non-destructive testing (NDT) to ensure strength, integrity, and dimensional accuracy.
Advantages of Using SS 304 Welded Round/Square Pipes
- Cost-Effective Alternative – Welded pipes are more affordable than seamless pipes without compromising performance.
- High Dimensional Accuracy – Consistent wall thickness and precise dimensions make them ideal for custom fabrication.
- Lightweight Yet Strong – Ideal for structural applications that require strength without excessive weight.
- Low Maintenance – Long-lasting, rust-free performance reduces maintenance costs.
- Eco-Friendly – 100% recyclable and sustainable material choice.
