Kanzen Tetsu supplies stainless steel round tubes for ornamental, architectural, mechanical and general fabrication applications in Malaysia. These tubes are designed for projects that require a clean round profile, reliable strength, corrosion resistance, and a consistent stainless steel finish.
Our stainless steel round tubes are part of Kanzen Tetsu’s stainless steel ornamental tubing range. They conform to ASTM A554, a recognised standard for welded stainless steel mechanical and ornamental tubing. They are available in 304 and 316 stainless steel grades, with multiple outside diameters, wall thicknesses and surface finishes to support different project requirements.
What Is a Stainless Steel Round Tube?
A stainless steel round tube is a hollow cylindrical tube made from stainless steel. It is widely used in both decorative and functional applications because of its clean appearance, strength, durability and resistance to corrosion.
Its smooth circular profile makes it suitable for visible structures, handrails, railings, furniture, architectural details, commercial fittings and customised fabrication works.

Available Stainless Steel Grades
Kanzen Tetsu stainless steel round tubes are available in both 304 and 316 grades. The right grade depends on the application, environment and corrosion resistance requirement.
1. 304 Stainless Steel Round Tube
304 stainless steel round tube is suitable for general ornamental, architectural and fabrication applications. It is commonly used for indoor areas, covered spaces, commercial fittings, furniture, handrails, railings and general stainless steel structures.
304 grade is widely selected because it offers good corrosion resistance, durability and workability for many standard applications.
2. 316 Stainless Steel Round Tube
316 stainless steel round tube is suitable for applications that require stronger corrosion resistance. It is commonly considered for coastal areas, outdoor environments, high moisture areas, marine adjacent applications and projects exposed to more demanding conditions.
316 grade is often selected when the project requires better resistance against corrosion compared to 304 stainless steel.
For a detailed explanation of both grades, read Kanzen Tetsu’s Stainless Steel 304 vs 316 Difference Guide.

Available Finishes for Stainless Steel Round Tube
Kanzen Tetsu supplies stainless steel round tubes in several finish options to support different design, fabrication and visual requirements.
1. Mill Finish
Mill finish is the basic surface finish produced during manufacturing. It is suitable for applications where surface appearance is not the main focus or where further processing will be carried out.
2. #180 Finish
#180 finish provides a smoother and more refined surface compared to mill finish. It is commonly used for general ornamental and fabrication applications.
3. #180 Hairline Finish
#180 hairline finish gives the stainless steel round tube a linear brushed appearance. It is suitable for visible applications where a clean decorative surface is required.
4. #400 Finish
#400 finish offers a smoother and brighter surface. It is often used in architectural, commercial and decorative applications where appearance matters.
5. #600 Finish
#600 finish provides a finer and more polished surface. It is suitable for applications where a more premium stainless steel appearance is required.
Common Applications of Stainless Steel Round Tube
Stainless steel round tubes are used in residential, commercial and industrial projects. Their circular profile makes them suitable for both visible design features and functional fabrication works.
| Application | Description |
|---|---|
| Handrails and railings | Used in staircases, balconies, walkways and safety barriers |
| Furniture fabrication | Suitable for chairs, tables, frames and decorative furniture |
| Architectural structures | Used in visible design features, building details and interior elements |
| Commercial fittings | Commonly used in retail spaces, counters, racks and display structures |
| Decorative works | Suitable for ornamental structures and stainless steel design features |
| General fabrication | Used by fabricators for customised stainless steel works |
How to Select the Right Stainless Steel Round Tube
When selecting a stainless steel round tube, consider four main factors: grade, outside diameter, wall thickness and finish.
The grade affects corrosion resistance and suitability for the environment. The outside diameter and wall thickness affect the strength, weight and fabrication requirement. The finish affects the final appearance of the tube, especially for visible or decorative applications.
Customers are encouraged to review the dimension and weight chart before submitting an enquiry. This helps ensure that the selected size and thickness match the project requirements.
