A36 Hot Rolled Steel is a low-carbon structural steel with a minimum yield strength of 36,000 PSI. The hot rolling process gives it a characteristic blue-grey mill scale finish and slightly rounded edges. Conforming to ASTM A36, this material is valued for its strength, formability, and outstanding weldability, making it a primary choice for construction and industrial fabrication where precise tolerances are not critical.
As a medium-width flat bar, this 3" x 1/8" size provides a balance of strength and versatility. It is commonly used for fabricating structural bracing, equipment bases, wear strips for machinery, and mounting plates that require good load distribution and easy drilling or welding for assembly.
