Rectangular Tube

Rectangular Tube

Stainless steel rectangular tubes are hollow profiles with flat sides and right-angle corners, designed for strength, stability, and clean architectural appearance. Manufactured from corrosion-resistant stainless steel grades such as 304, 304L, 316, and 316L, they are widely used in construction, industrial fabrication, architectural framing, furniture, and transportation systems.

These tubes are primarily produced as welded (ERW or TIG) sections in accordance with ASTM A554, ASTM A312, and EN 10296-2 standards. The production process involves cold-forming stainless steel strip into rectangular shape, welding the longitudinal seam, and then sizing and straightening the profile to meet strict dimensional tolerances. The result is a smooth, uniform tube suitable for both visible and structural applications.

Dimensional availability typically ranges from 10 × 20 mm up to 200 × 100 mm, with wall thicknesses from 0.8 mm to 8 mm, supplied in 6-meter lengths or cut to size. The rectangular geometry provides greater directional strength compared to round tubing, making it ideal for frameworks, columns, and load-bearing assemblies.

Surface finish options allow the product to adapt to different requirements:

  • Mill Finish: Raw, unpolished surface used for fabrication and mechanical applications.
  • Satin / Brushed Finish (180–320 grit): Fine, matte appearance suitable for architectural interiors, railings, and structural elements.
  • Mirror Finish (600 grit and above): Highly reflective surface for decorative or sanitary use, common in design and furniture industries.


All polished tubes are protected with film or paper wrapping to preserve the surface during transport and handling.

Material grade selection depends on environment and use. Grade 304 / 304L is the standard choice for general and indoor applications, offering good corrosion resistance and ease of fabrication. Grade 316 / 316L, containing molybdenum, performs better in marine, chemical, or outdoor conditions with exposure to chlorides or moisture. The low-carbon “L” variants are recommended when extensive welding is required.

Stainless rectangular tubing can be easily fabricated — it can be cut, bent, or welded using standard stainless procedures without loss of performance. The flat surfaces and sharp corners make it particularly suitable for frames, support structures, machine guards, and architectural façades where alignment and visual uniformity are important.


Common applications include:

  • Architectural and structural frameworks
  • Equipment supports, conveyors, and mechanical structures
  • Furniture, shelving, and interior fittings
  • Transportation, trailers, and vehicle bodywork
  • Food-processing, pharmaceutical, and clean-room equipment


Products are supplied according to recognized international standards (ASTM A554 / EN 10296-2), ensuring consistent strength, weld integrity, and surface finish. Certificates and traceability can be provided where required.

In summary, stainless steel rectangular tubes offer a combination of rigidity, corrosion resistance, and precise geometry. Their flat-sided profile provides strong load-bearing performance while maintaining a refined, professional appearance. Available in multiple grades, finishes, and sizes, stainless rectangular tubing remains a fundamental material for architectural, industrial, and fabrication projects throughout Canada and globally.

Product Description

Stainless steel profiles with corrosion-resistant properties are steel models that have existed for over 100 years, produced as a result of various tests and research. They are widely used across many sectors, especially in the construction industry, due to their extremely strong structure in terms of durability. Known for their resistance to corrosion, stainless profiles are also suitable for long-term use due to their bright appearance and easy-to-clean feature.

Corrosion, defined as metal decay, technically occurs when metal reacts with oxygen. In such cases, the metal loses its durability under challenging conditions and deteriorates. Due to problems such as decay or wear in metals, metals with high resistance to corrosion should be used in your projects. This allows stainless steel to be used across various fields.

Due to its corrosion-resistant structure, stainless U-profile and stainless profile types are frequently preferred in many industries, and stainless box profiles can also be easily acquired.

Stainless Steel Profiles

Stainless steel profiles, which are widely used in Turkey and compatible with many sectors, are produced in square or rectangular cuts. These types of cuts offer many advantages. Primarily, they are widely used for assembly and have the advantage of being aesthetically appealing, making stainless steel profiles a preferred choice for every user.

In terms of structure and shape, steel profiles have specific features that are classified under different terminologies. They come in H-shaped, U-shaped, or I-shaped forms. In this way, the use of steel profiles is generally categorized based on cut types across various fields. Therefore, the range of applications varies widely according to the shape of the stainless steel profiles.

To meet the quality standards in Europe, S235/S275 quality is expected in steel profiles commonly used in Turkey. Steel profiles preferred for these features have a solid and widespread usage thanks to their well-defined structural characteristics. Additionally, stainless steel profiles vary entirely according to their production shapes, which can also change depending on the intended project areas. These shapes are identified directly with letters: C, U, Z, and sigma profiles.

Profiles produced in various shapes for different projects are entirely associated with their corresponding shapes. At the same time, the reason for this selection is the ease of nesting or disassembling, making them practical to use. These features bring out the best use of profiles.

Advantages of Stainless Profiles

Stainless profiles are frequently used today, with their corrosion-resistant property considered among their primary advantages. The inclusion of a steel and chromium alloy makes these materials suitable for use in various industries. Stainless profiles are highly valuable in the construction sector in every aspect. One of the reasons for choosing stainless profiles is their resistance to corrosion and oxidation.

With the production of stainless profiles with high-quality characteristics, these materials have also started to be preferred in the decoration sector. Stainless profiles suitable for a wide range of applications are generally adaptable for use across nearly all sectors. Some of the industries where stainless profiles are most commonly used are:

  • Furniture industry
  • Automotive industry
  • Textile industry
  • Heavy industry and ship manufacturing
