Round hollow section metal tubes (also known as circular hollow sections or CHS) are versatile and widely used in various applications due to their strength, durability, and aesthetic appeal. Here are some examples of where these tubes are commonly used:

1. Furniture (Chairs, Tables, etc.)

• Chairs: Round hollow section tubes are frequently used in the frames of office chairs, stools, dining chairs, and lounge chairs due to their strength, light weight, and modern aesthetic.
• Tables: The legs of tables, especially in minimalist or industrial-style furniture, often utilize round hollow sections for both structural integrity and design.

2. Architectural Structures

• Handrails and Guardrails: Round hollow sections are often used for handrails in stairs, balconies, and ramps due to their smooth finish and ability to withstand heavy loads.
• Structural Frames: Used in the construction of buildings, bridges, and other structures for columns, beams, and supports because of their ability to bear weight evenly in all directions.

3. Automotive Industry

• Chassis and Roll Cages: In racing cars or high-performance vehicles, round hollow sections are used for the chassis and roll cages for safety and rigidity.
• Exhaust Pipes: These tubes are often used for exhaust systems because of their ability to withstand high temperatures and corrosive environments.

4. Piping Systems

• Water Supply & Drainage: Round hollow tubes are commonly used in plumbing for water supply lines, drainage systems, and sewer pipes.
• Gas Supply Lines: They are also utilized in industrial and residential gas distribution networks.

5. Sports Equipment

• Bicycles: Round hollow sections are used in the frames of bicycles due to their ability to combine lightness and strength.
• Golf Clubs: The shafts of some high-end golf clubs are made from hollow round tubes for improved performance and reduced weight.

6. Marine and Boating

• Boat Railings and Fittings: Round hollow sections are frequently used for railings, poles, and other structural elements in boats and ships.
• Anchor Systems: These tubes can be part of the anchor structures for marine vessels, providing both strength and resistance to corrosion.

7. Agriculture and Outdoor Equipment

• Fencing: Round hollow sections are often used in the construction of fencing systems for farms, parks, and industrial areas due to their resistance to wear and tear.
• Greenhouses: They are commonly used in the frame construction of greenhouses because of their strength and longevity, especially when exposed to outdoor elements.

8. Railway and Transport Infrastructure

• Railway Tracks and Supports: Used in the construction of railway track systems, including cross-ties, guard rails, and structural supports.
• Transport Trailers: Round hollow sections are used for the framework of trailers, trucks, and containers due to their strength and ability to distribute weight evenly.

9. Signage and Lighting

• Street Lamps: Round hollow sections are commonly used for lamp posts and street lighting structures because of their ability to resist bending and corrosion.
• Advertising Boards: The frames for outdoor signage often utilize these tubes for their stability and resistance to the elements.

10. Heavy Equipment and Machinery

• Forklifts and Cranes: Round hollow sections are used in the manufacture of heavy-duty machinery like forklifts, cranes, and other lifting equipment, where structural strength is essential.
• Storage Racks: Heavy-duty shelving and storage racks for industrial use often employ round hollow sections for the vertical and horizontal framing.
