Hollow Sections
Hollow Sections
Compared to solid sections, hollow sections are lighter, which makes them easier to handle and transport during construction. They can provide similar or even better structural performance in terms of resisting bending and torsion forces while using less material.
HSS profiles meet many international standard specifications, including ASTM A500, A1085 and A1065. This type of tube or profile is commonly used in various engineering and construction projects.

Hollow Structural Sections (HSS): These are commonly made of steel and have shapes like square, rectangular, or circular.

Types Of Hollow Structural Sections
Square Hollow Section (SHS)
Square hollow section, also known 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.
Our Advantages
Welded pipes are generally more cost-effective to produce. The manufacturing process of welded pipes is relatively simple. They are made by bending a steel plate or strip into a tubular shape and then welding the seam, which requires less complex equipment and technology, resulting in lower production costs.Due to the lower manufacturing cost, welded pipes are usually cheaper in the market. For projects with a large demand for pipes but not extremely high requirements for pipe performance, using welded pipes can significantly reduce material costs.
| Welded Pipe | Seamless Pipe |
|---|---|
| Cheaper option compared to seamless pipes | More expensive than welded pipe |
| It has welding seam on tube | No welding seam on the tube |
| Main raw material: steel coils and strips | Made of solid round bars |
| High production efficiency | High OD and ID tolerance |
| Thickness tolerance is moderately precise | Can bear high-pressure |
| Used for low/medium pressure applications | Thickness tolerance is stable and accurate |
