Applications

N/A For use in riveted, bolted, or welded construction of bridges and buildings, and for general structurals purposes.

Mechanical Properties

N/A ASTM A 36 requirements are:
Tensile Strength - 58.000/80.000 psi
Yield Point - 36,000 Min. psi
Elongation in 8" - 20% Min. (Subject to a deduction from trie above percentage of elongation for thicknesses under 5/16" and over 3/4".)

Weldability

N/A These shapes are easily welded by all the welding processes, and the resultant welds and joints are of extremely high quality. The grade of welding rod to be used depends on thickness of section, design, service requirements, etc.
