ASTM A500 tube features
High strength and durability
ASTM A500 tubes have high yield and tensile strengths ranging from 33,000 psi (Class A) to 50,000 psi (Class C/D) and 45,000 psi to 70,000 psi.
The high strength allows it to withstand heavy loads and high stress conditions, making it particularly suitable for structural applications.
Good weldability and workability
The pipe has excellent weldability and the cold forming process makes it difficult to lose its structural integrity during welding.
It has good ductility and impact resistance, and can adapt to complex processing needs.
Strict tolerance control
The outer diameter tolerance is ±1%, the wall thickness tolerance is ±10%, and the length tolerance is usually within ±6 mm to ensure the reliability of the structural application.
Corrosion resistance
Although its own corrosion resistance is general, but by galvanizing or painting surface treatment, can enhance its durability in harsh environments.
A variety of shapes and sizes
ASTM A500 tubes are available in round, square and rectangular shapes and in a wide range of sizes, from 6.35 mm to 660 mm outside diameter and 1.27 mm to 16 mm wall thickness.
The side length and wall thickness of square and rectangular tubes are also available in a variety of specifications to meet different engineering needs.
ASTM A500 tube application
Construction industry
Widely used in steel structure frame, columns, beams, stairs, railings and other building bearing structure.It is also used for load-bearing components in bridge construction.
Industrial manufacturing
Used for mechanical frame, bracket, transmission system support and industrial equipment.
Transportation
Used for railway track support, signal towers, car and truck frames, ship structural frames, etc.
Municipal infrastructure
Used for street lighting, utility poles, traffic sign support, water pipes and pipe supports.
Agriculture and irrigation systems
Used in irrigation systems, greenhouse structures and agricultural machinery supports.
The oil and gas industry
Structural support systems used in the construction of oil RIGS, pipelines and oil facilities.
