RIGHT CORNER HOLLOW SECTIONS

Tianjin Lefin Industrial Co., Ltd is one of the most experienced manufacturers and suppliers of right corner hollow sections in China. Please feel free to buy high quality right corner hollow sections from our factory. Good service and reasonable price are available.

The RIGHT CORNER HOLLOW SECTION is a kind of metal profile commonly used in structural engineering. Its core features are that the section shape is right Angle and the interior is hollow.

• Right Angle Angle: The four corners of the section are 90° right angles (different from rounded or oblique profiles), which makes the profile easier to align when connected, especially suitable for structural scenes that require right Angle splicing.

• Hollow section: A closed geometry (e.g. square, rectangle) with no filling inside, which enables lightweight by reducing the amount of material used while maintaining high flexural and torsional stiffness.

• Common materials: carbon steel, stainless steel or aluminum alloy, through cold forming or welding process.

(1) Divided by section shape

• Square Hollow Section (SHS, Square Hollow Section) : right-angle section with four equal lengths, suitable for symmetrical stress scenarios (such as building columns, truss joints).

• Rectangular Hollow Section (RHS, Rectangular Hollow Section) : It varies in length and width, and is suitable for structures requiring unidirectional load (such as beams, frame struts).

(2) Divided by manufacturing process

• Cold-formed: by roller forming, the surface is smooth but the wall thickness is slightly less uniform, suitable for light structures.

• Welded forms: Welded from steel sheets for more uniform wall thickness and higher strength, often used in heavy industrial structures.

Advantages:

• High rigid-to-weight ratio: Hollow design reduces material usage while maintaining structural strength.
• Easy connection: right-angled edges are easy to bolt, weld or fix with mechanical fixtures.
• Corrosion resistance: If galvanized or aluminum alloy material is used, it can adapt to outdoor or humid environment.

Limitations:

• Stress concentration: It is easy to produce stress concentration at right angles, which needs to be optimized by chamfering or reinforcing plates.

• Manufacturing complexity: Welded profiles require higher process accuracy and may cost more than open section profiles (such as Angle steel).

Circular hollow profile (CHS), whose four corners are arc transition, is mainly used in fluid pipelines and decorative structures.

Open section profile (Angle steel), for non-closed section, the main application is temporary support, low-cost frame.

Right Angle hollow profiles (RHS) are closed right Angle sections, mainly used in permanent building structures and mechanical frames.
