Stainless Steel Profiles (Square & Rectangular Tubes, Pipe, Tube, Flat Bar, Angle, Round Bar) (ASTM A554 & ASTM A276)


ASTM A554 & ASTM A276


Square and Rectangular Profiles:

Areas of Use: Structural elements in the construction industry, furniture making, door and window frames, decorative applications.
Characteristics: Rectangular profiles have a rectangular cross-section, while square profiles have a square shape with equal sides. They are available in different sizes and thicknesses.

Round Profiles:

Areas of Use: Stair railings, hand rails, decorative bars, exhaust systems.
Characteristics: Round profiles are available in various diameters and thicknesses. They are especially preferred for decorative and tubular applications.

I and H Section Profiles:

Areas of Use: Structural carriers, beams, bridges in the construction industry.
Characteristics: I and H section profiles are designed to increase structural strength. I-section profiles resemble an “I” shape, while H-section profiles resemble a wider “H” shape.

T and U Profiles:

Areas of Use: Frames, door frames, conveyor systems, load-bearing elements.
Characteristics: T profiles have a “T” shaped cross section, while U profiles have a “U” shaped cross section. These profiles are generally used in structural elements and frames.

L Profiles (Angle Brackets):

Areas of Use: Wall corners, frames, furniture construction, shelving systems.
Characteristics: L profiles have an “L” shaped cross section with one side longer than the other. They are also known as angle brackets and are used to protect or support corners.

Z and C Profiles:

Areas of Use: Wall cladding systems, ceiling structures, roof supports.
Characteristics: Z and C profiles have “Z” and “C” shaped sections. They are generally used as structural elements in the construction industry.

The range of stainless steel profiles comes in different sizes, thicknesses and surface treatments to adapt to specific applications. Selecting the right profile according to the application needs and technical requirements is critical for a successful project or application.

Stainless Steel Profile Sizes and Standards

There are various internationally recognized standards for the production and use of stainless steel profiles. These standards determine important technical specifications such as material properties, dimensions and tolerances. Here are some commonly used stainless steel profile standards:

  1. EN 10088-3 (European Norm): This European standard specifies the properties and chemical composition of stainless steel profiles. Technical properties of stainless steel profiles such as material grade, hardness, mechanical properties and corrosion resistance are determined by this standard.
  2. ASTM A276 (American Society for Testing and Materials): This American standard defines the chemical composition, mechanical properties and dimensions of stainless steel profiles. In particular, A276 has standards for stainless steel bars, profiles and seamless tubes.
  3. ASTM A479: “Standard Specification for Stainless Steel Bars and Shapes for Use in Boilers and Other Pressure Vessels,” is a standard for stainless steel bars and shapes used in pressure vessels and other industrial equipment. This standard specifies the technical requirements and properties for the manufacture and use of stainless steel bars and shapes. ASTM A479 was developed to ensure the quality and suitability of various stainless steel bars used in industrial applications.
  4. ASTM A554: Known as “Standard Specification for Welded Stainless Steel Mechanical Tubing”, is a standard for stainless steel welded mechanical tubing and pipe sections. This standard specifies the technical requirements and specifications for the manufacture and use of stainless steel pipes and tubing. ASTM A554 was developed to ensure the quality and suitability of welded stainless steel mechanical tubing, which is important for many industrial applications.
  5. JIS G 4317 (Japanese Industrial Standards): JIS G 4317, a standard used in Japan, covers the material grades, chemical composition and dimensions of stainless steel profiles.
  6. DIN 1021 (Deutsches Institut für Normung): DIN 1021, a standard used in Germany, specifies the properties and tolerances of stainless steel profiles. This standard includes specific requirements for various types of stainless steel profiles.

The dimensions and tolerances of stainless steel profiles are usually based on the standards set by the manufacturer for its products and the needs of the customer. However, the standards mentioned above provide general guidelines and offer dimensions and tolerances that are accepted throughout the industry.

To meet the standards required for a specific project or application in terms of size, quality and fit, the type of stainless steel profile and manufacturer should be carefully selected. This is critical to the success and longevity of the project.

The technical characteristics of stainless steel profiles may vary depending on the application and area of use. However, they generally have the following properties:

  • Rust resistance: Stainless steel has excellent resistance to corrosion and is therefore suitable for use outdoors or in chemical environments.
  • Durability: The mechanical properties of stainless steel profiles include parameters such as tensile strength, tensile strength, modulus of elasticity and hardness. These properties determine the load carrying capacity and durability of the profile. Stainless steel is a material that can withstand high temperature and pressure.
  • Aesthetic Appearance: Stainless steel has a modern and aesthetic appearance and is therefore preferred for decorative applications.
  • Cleaning and Hygiene: Stainless steel is easy to clean and hygienic, so it is used in food processing, healthcare and laboratory applications.
  • Weldability: Weldability of stainless steel profiles is important in assembly and construction stages. Appropriate welding methods and equipment may be required to maintain the material properties during welding and to prevent damage to the stainless properties.
