Dang Steel, a well-respected manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality ASTM A500 Tubing, crafted with meticulous attention to ASTM standards. This standard encompasses cold-formed, welded, and seamless carbon steel structural tubing available in round, square, and rectangular shapes. Renowned for its strength, durability, and impressive load-bearing capabilities, this tubing finds extensive use in construction, structural frameworks, and various mechanical applications. With state-of-the-art production facilities and rigorous quality control measures, Dang Steel guarantees precise dimensions, resistance to corrosion, and reliable performance, catering to both local and international markets.
ASTM A500 Tubing comes in several grades (A, B, C, and D), with carbon content typically ranging from 0.26% to 0.30% and manganese levels between 0.75% and 1.35%. The mechanical properties differ by grade: yield strength spans from 228 MPa (Grade A) to 317 MPa (Grade C/D), while tensile strength varies from 310 to 400 MPa. It boasts excellent toughness, formability, and weldability, making it ideal for load-bearing and structural uses. The cold-forming process enhances dimensional accuracy and boosts mechanical strength.
