A709 GR.50 CARBON STEEL H BEAM is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural plates in the construction of bridges. SSAB offers the following five grades of A709; 36, 50, 50W, HPS 50W and HPS 70W. The three weather grades of 50W, HPS 50W, and HPS 70W have an ASTM G101 enhanced Atmospheric Corrosion Resistance Index of ≥6.0.

A high-strength, low-alloy structural steel plate utilized primarily in the manufacture of bridges. Chapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. These grades are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test (Frequency "P"). Bridge steels can also be ordered to the ASSHTO M270 Specification referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W.
