ASTM A500 Gr. B Hot Finish Rectangular Hollow Section
Ranfit Metal is a well-known manufacturer, supplier, and stockiest of ASTM A500 Gr. B Hot Finish Rectangular Hollow Section. Hot-finished Gr. B RHS are manufactured to meet the ASTM A500 specification, which covers cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.
The hot finish process of Gr. B Rectangular Hollow Hot-finished Sections ensures that the product is strong and able to withstand heavy loads and extreme weather conditions. ASME SA500 Gr. B Hot Finished Rectangular Hollow Section Welded Tube has a minimum yield strength of 50,000 psi (345 MPa) and a minimum tensile strength of 65,000 psi (450 MPa). ASME SA500 Gr. B HFRHS is a versatile and high-performance structural steel tubing that is widely used in various industries and applications. Its unique combination of strength, durability, and corrosion resistance of ASTM A500 Gr. B Seamless RHS Pipes makes it an ideal choice for projects where structural integrity is critical.
Hot Finish ASTM A500 Gr. B Rectangular Hollow Section are commonly used in building frames, bridges, and other infrastructure projects where high strength-to-weight ratios are required. The rectangular shape provides excellent resistance to bending and torsion, making it an ideal choice for applications where structural integrity is critical.
ASTM A500: Hot Finish is a carbon steel hollow section pipe.
Grade A: is the lowest strength grade under ASTM A500, primarily used for structural applications where higher grades (B, C, D) are unnecessary.
