Import Astm A500 Grade B 40*40 Steel Square Pipe — Buy in wholesale FOB from Supplier in China

Hebei Borun Steel Trade Co., Ltd supplies ASTM A500 Grade B steel square pipe in a 40 mm by 40 mm cross-section, a cold-formed welded structural hollow section for construction and mechanical applications. The material is carbon steel ASTM A500 Grade B, with the supplier specifying this grade for its balance of strength and formability in structural frameworks. The 40x40 mm outer dimension represents a common metric size in Asian production, typically supplied in 6-meter or 12-meter standard lengths or cut to customer requirements.

ASTM A500 Grade B specifies minimum yield strength of 46,000 psi and minimum tensile strength of 58,000 psi, with carbon content limited to 0.26% maximum. The square profile offers efficient torsional resistance and clean architectural lines, with typical wall thickness for this size ranging from 2.0 mm to 3.0 mm for standard structural loads. Hebei Borun notes capability across square tube outer dimensions from 20x20 mm to 1000x1000 mm and wall thicknesses from 2 mm to 35 mm, suggesting the 40x40 mm sits within a well-established production range. The supplier also lists compatibility with DIN EN10210, EN10219, GB/T3094-2000, JIS G 3466, and GB/T6728-2002 standards.

Applications span petrochemical infrastructure, power generation facilities, agricultural irrigation systems, urban construction, and pipeline transmission.
