We have world-leading production equipment and strong manufacturing capabilities. Please feel free to buy bulk durable astm a500 rectangular steel tube from our factory.

Tianjin Brisk Metalwork Co.,Ltd  is one of the Chinese manufacturers of ASTM A500 Steel Tube, and our products mainly exported to the Middle East, Southeast Asia, Africa, and other regions for oil refining projects and power plant construction projects, it serves as the core piping for high-temperature and high-pressure fluid transportation and is often used in combination with API 5L pipeline steel and ASTM A53 seamless pipes.

• ASTM A500 is the core standard for U.S. cold-formed welded/seamless carbon steel structural square and rectangular tubes, covering steel grades A, B, C, and D. It is characterized by high strength, excellent formability, and superior welding performance, and is widely used in structural engineering projects in North America and international trade.

 

• Grade D needs heat treament.

 

GRADE	Field
A	Shelf columns, door and window frames, handrails and railings, agricultural equipment brackets, simple factory purlins
B	Multi-story residential steel frames, shopping mall decorative keel, pipe supports and hangers, small and medium-sized equipment racks
C	High-rise industrial building beams and columns, bridge longitudinal and transverse beams, crane runway beams, municipal guardrails, steel structure platforms, seismic supports
D	Bridges in cold regions, mining equipment supports, port machinery, auxiliary structures for wind turbine towers, low-temperature storage tank supports

• Prioritize cost and lightweight structure: choose Grade A/B.

 

• Medium to high strength, industrial/bridge projects: choose Grade C (the most commonly used steel grade)

 

• For low temperatures (≤-20℃), dynamic loads, or critical structures: choose Grade D.

 

• Grade A/B focuses on low cost and formability, Grade C focuses on high strength, and Grade D requires heat treatment, with excellent low-temperature toughness, meeting personalized needs for different loads and environments.

 

• As a mainstream standard for structural engineering in North America, ASTM A500 square and rectangular tubing is recognized by most countries worldwide.
