ASTM A500 Gr. C Square Hollow Section
Ranfit Metal is a well-known manufacturer, supplier, and stockiest of Cold Formed ASTM A500 Gr. C Square Hollow Section. Cold-formed ASTM A500 Grade C square hollow sections (SHS) are structural steel tubing made to the ASTM A500 specification, a standard in the U.S. for cold-formed, welded, and seamless carbon steel structural tubing.
The Cold Formed ASTM A500 GR C Square Hollow Section Produced without heating the material to high temperatures, improving dimensional accuracy and surface finish. ASTM A500 Gr Cold Formed Welded Structural Square Tubing is distinguished by its durability due to the use of high-quality raw materials, good conductivity and welding qualities, and corrosion resistance to a wide range of corrosive environments. Outside dimensions of A500 Gr, C SHS Pipes, as measured across the flats at least 2 inches [5 centimeters] from the tube ends, shall not differ by more than the tolerance for convexity or concavity. For ASTM A500 Grade C structural tubes, the allowable variance is 1/8in. times the number of feet [10 mm times the number of meters] divided by 5.
ASTM A500 Gr C Square Tube is designed with a square cross-sectional area with all sides having equal lengths. The Cold Formed ASTM A500 Gr C Square Hollow Section has high tensile strength and is utilized for construction and oil field services.
ASTM A500: Stands for Standard specification for cold-formed steel structural tubing.
Grade C: Represents Grade C, which is the highest strength designation under the ASTM A500 standard.
