What is the use of a hollow square bar?

Hollow square bars, also known as square tubes or square hollow sections (SHS), have diverse applications across various industries. They mainly provide structural support and strength in different construction and fabrication projects. Hollow square bars are commonly used in building frameworks, support columns, trusses, and beams in the construction industry.

What are Hollow Square Bar Standard Sizes?

Hollow Square Bars come in various standard sizes, and the specific dimensions can vary depending on the material and manufacturing standards. Commonly available sizes include dimensions for the square cross-section (side length) and thickness (wall thickness). Some typical sizes might be, for instance, 1" x 1" with a 1/8" wall thickness or 2" x 2" with a 1/4" wall thickness.

What are the benefits of using Stainless Steel Square Hollow Sections?

Stainless Steel Square Hollow Sections are known for their exceptional corrosion resistance, making them suitable for outdoor and aggressive environments. Additionally, SS SHS provides an excellent strength-to-weight ratio, aesthetic appeal, and low maintenance requirements, making them ideal for architectural, construction, and industrial applications.
