American Structural Beams

American Structural Beams are structural steel members primarily used for load-bearing, framing and support applications in buildings, industrial facilities, infrastructure and engineered steel structures.

Their engineered cross-sectional geometry provides the required strength, stiffness and structural efficiency for transferring loads across structural frameworks. The appropriate beam section is selected according to the required span, loading conditions, section properties, connections and engineering design.

American Structural Beams commonly include W-shapes (Wide Flange Beams), S-shapes and other structural sections specified according to applicable AISC section standards and ASTM material specifications.

W-shape beams are widely used in modern steel construction because their wide flanges provide useful structural properties for beams and columns. Other sections may be selected according to the requirements of a particular structural design.

At Moksh Tubes & Fittings LLP, we support American Structural Beam requirements based on customer drawings, technical specifications and project requirements. Customers can specify the required beam designation, section size, material grade, length, quantity and applicable ASTM / AISC specification.

American Structural Beams can also be used together with American Structural Angles, Channels, Columns and Hollow Structural Sections (HSS) to create complete steel frameworks and fabricated structural assemblies.

For an accurate quotation, customers can provide their required beam section, designation, dimensions, material grade, length, quantity and applicable ASTM / AISC requirements, along with project drawings or technical documentation where required.
