ASTM A500 Carbon Steel Tubes Supplier

BAOWI STEEL MANUFACTURING CO.,LTD is a well-established manufacturer, supplier and distributor of square and rectangular tubes. ASTM A500 Carbon Steel Tube (also known as A-500) is a standard specification for cold-formed welded seamless carbon steel structural tubes in round, square and rectangular shapes. The most commonly used specification for hollow structural sections (HSS) is ASTM A500. A500 Carbon Steel Structural Tube is made entirely of materials compatible with carbon steel. A500 is primarily iron with added carbon, manganese, phosphorus, sulfur and copper.

ASTM A500 is a standard published by ASTM that covers the requirements for cold-formed welded and seamless carbon steel structural pipes. ASTM A500 is an important standard published by the American Society for Testing and Materials (ASTM) that specifies the chemical composition, mechanical properties, and inspection and packaging requirements of ASTM A500.ASTM A500 requires that structural steel pipes are made of carbon steel that meets specific chemical composition and mechanical property requirements. This helps ensure that the pipes can withstand appropriate loads and pressures in various engineering environments.A500 cold-formed tubes are divided into four categories based on chemical composition, tensile strength and heat treatment. Square and rectangular tubes have higher yield strength requirements than round tubes. Minimum copper content is optional. Grade D must be heat treated.

ASTM A500 Grade B/Grade C Production Process

ASTM A500 covers two main manufacturing processes: cold-formed welding and seamless production.

Cold-formed welding is the process of bending a flat plate into a tubular shape and connecting it by welding. On the other hand, seamless pipes are directly formed into a pipe shape without welding.

These diverse manufacturing processes provide flexibility to meet different needs

Advantages of ASTM A500 Carbon Steel Structural Pipe

ASTM A500 carbon steel structural pipe is highly valued in construction for its excellent quality. It has excellent weldability, ensuring strong joints that are critical to structural integrity. Its good machinability enables precise shaping, which improves manufacturing efficiency. In addition, A500 pipe is also known for its excellent cold workability, which maintains strength and shape at room temperature. Its aesthetic appearance makes it suitable for architectural use. Common applications include structural supports, building columns, highway signs, and communication towers, demonstrating its durability and versatility in a variety of engineering projects.

Applications of ASTM A500 Steel Structural Tubes

Depending on their size, A500 structural tubes can be used in construction, heavy equipment, agriculture, machinery, manufacturing, and general structural purposes. In construction, they are often used as support beams or columns. In heavy equipment manufacturing, they are used in the construction of machinery such as tractors and excavators. In agriculture, they are often used in the construction of irrigation systems. In manufacturing, they are often used to create sections of steel beams and columns. Therefore, ASTM A500 structural tubes have a wide range of applications in many industries. ASTM A500 tubes are available in four grades: Grade A, Grade B, Grade C, and Grade D. Each grade has specific chemical requirements as well as different mechanical property requirements that must be met to be considered compliant with the ASTM A500 standard.

ASTM A500 Carbon Steel Structural Tube is favored by the construction industry for its many advantages. It has excellent weldability and can easily and firmly connect parts. Its machinability enables precise shaping and modification, while its cold workability means it can be formed without heating, thus maintaining its strength. Appearance-wise, it has an aesthetically pleasing surface suitable for a wide range of applications. Common uses for A500 pipe include structural supports, building columns, highway signs, oilfield equipment, and communication towers, demonstrating its versatility and reliability in demanding environments.
