Stainless Steel Angle Bar from China: Sizes, Grades, and Applications

Stainless steel angle bars are widely used in construction, manufacturing, and engineering projects due to their strength, durability, and excellent corrosion resistance. As one of the most commonly exported steel products from China, stainless steel angle bars are available in a wide range of sizes and grades to meet different industrial needs.

What Is a Stainless Steel Angle Bar?

A stainless steel angle bar (also called stainless steel angle or L-shaped steel) is a structural steel product formed into a 90-degree angle. It typically comes in equal or unequal leg lengths and is used to provide reinforcement, support, and structural stability in various applications.

Thanks to its corrosion resistance and mechanical strength, it is suitable for both indoor and outdoor environments, including harsh industrial conditions.

Common Sizes of Stainless Steel Angle Bars

Stainless steel angle bars are manufactured in various dimensions to suit different engineering requirements. Common size ranges include:

• Leg size: 20mm × 20mm up to 200mm × 200mm

• Thickness: 3mm to 20mm

• Length: Typically 6 meters or customizable upon request

Equal angle bars have both sides of the same length, while unequal angle bars feature different side lengths to support specialized structural designs.

Stainless Steel Grades Used

Different stainless steel grades are selected depending on strength, corrosion resistance, and application environment. The most commonly used grades include:

304 Stainless Steel

• Most widely used grade

• Good corrosion resistance and formability

• Suitable for general construction and indoor applications

316 Stainless Steel

• Higher corrosion resistance, especially against saltwater and chemicals

• Ideal for marine, coastal, and chemical industries

201 Stainless Steel

• More economical option

• Suitable for decorative and light structural applications

• Lower corrosion resistance compared to 304 and 316

Manufacturing Standards

Stainless steel angle bars from China are typically produced according to international standards such as ASTM, AISI, JIS, and GB. These standards ensure consistent quality, mechanical performance, and dimensional accuracy for global markets.
