There are several international and national standards that govern the production and quality of rectangular steel tubes. One of the most widely recognized is the ASTM (American Society for Testing and Materials) standard. ASTM A500, for example, specifies the requirements for cold - formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It covers aspects such as chemical composition, mechanical properties, dimensions, and tolerances.
- ASTM A500 (USA): Standard specification for cold-formed welded carbon steel structural tubing.
- EN 10219 (Europe): Cold-formed welded structural hollow sections of non-alloy and fine-grain steels.
- JIS G 3463 (Japan): Carbon steel rectangular tubes for general structural purposes.
- GB/T 6728 (China): Cold-formed welded steel hollow sections for structural use.
Rectangular steel tubes are used in various industries, including:
Construction: Building frames, roof trusses, columns, and support structures.
Automotive & Machinery: Chassis, roll cages, and equipment frames.
Infrastructure: Bridges, guardrails, and signboard supports.
Furniture & Architecture: Modern furniture, handrails, and decorative structures.
Industrial Equipment: Conveyor systems, storage racks, and scaffolding.
Conclusion
Rectangular steel tubes offer superior structural performance, versatility, and cost efficiency, making them a preferred choice in engineering and construction. Compliance with international standards ensures reliability across different
