ASTM A500 Gr. B Square Hollow Section
Ranfit Metal is a well-known manufacturer, supplier, and stockiest of Cold Formed ASTM A500 Gr. B Square Hollow Section. ASTM A500 Grade B is a standard specification for cold-formed welded and seamless carbon steel structural tubing. When referring to square hollow sections (SHS), it describes square steel tubing with a uniform cross-section.
The Cold Formed ASTM A500 GR B Square Hollow Section comprises chromium, carbon, copper, and nitrogen content. These Cold Formed ASTM A500 Gr B Square Box Sections are manufactured using cutting-edge technology and excellent craftsmanship. It is prepared in accordance with international quality standards. It is made with materials that meet international requirements and specifications. The hollow section is widely employed in the construction of bridges and structures. This is a non-alloy product, made of steel. Cold Formed ASTM A500 Gr B Square Hollow Section is widely utilized in construction, particularly in the construction of buildings and bridges.
ASTM A500 Grade B SHS pipe has high strength, tensile strength, and malleability, making it suitable for handling significant pressures and loads. Its tremendous strength ensures long-term stability in building constructions and foundation work.
ASTM A500: Stands for Standard specification for cold-formed steel structural tubing.
Grade B: has the lowest yield strength compared to other grades (B, C, and D) in the ASTM A500 standard.
