Types Of Hollow Structural Sections
• Square Hollow Section (SHS)
Square hollow section, also knowm as SHS. it provides good stability in both horizontal and vertical directions, and is not easy to deform under pressure.The flat surface is convenient for cutting, bending, welding and other processing operations, and is easy to connect with other components.
• Rectangular Hollow Section (RHS)
Rectangular hollow sections (RHS) are often used in mechanical, structural, and construction work, just like square hollow sections. The pipe’s flat surface is more cost-effective for joining and other fabrication work.
• Circular Hollow Section (CHS)
CHS is made by rolling a flat steel sheet into a circular shape at a certain radius and then welding the seam. Widely used in construction Industry, parts and other fields. It is often used in the production of furniture such as tables, chairs, and beds to make legs and frames.
Specifications Of Hollow Structural Sections
The pipe manufacturing process makes a precise hollow section. It is strong enough to ensure the structure’s integrity. The production standards are strictly followed in manufacturing. It is available in different steel grades as well. These hollow sections are highly efficient and are used in various engineering and construction applications.

Hollow Section Manufacturing Process

Hollow Structural Sections Applications
Construction Industry: It is used as columns and braces in portal frame structures. It is also suitable for making scaffolding, stair railings, and decorative columns.
Mechanical Manufacturing: It is used to make mechanical parts such as shafts and hydraulic cylinders.
Transportation Industry: In the construction of vehicles and ships, CHS is used for making frames, guardrails, and some supporting structures.
Furniture Manufacturing: It is often used in the production of furniture such as tables, chairs, and beds to make legs and frames.
