- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
A36 hot rolled steel is a low-carbon structural grade produced to ASTM A36 standards. The hot rolling process results in a scaly, blue-grey mill finish and slightly rounded edges, making it a cost-effective choice for applications where precise tolerances are not critical. With a minimum yield strength of 36,000 PSI, it provides excellent strength and toughness. It is not heat treatable but is easily welded, formed, and machined.
As a medium-width flat bar, this 1-3/4" x 1/4" size is a versatile choice for fabricating structural bracing, base plates for medium-duty equipment, wear strips, and support brackets where reliable strength and easy weldability are key project requirements. It is a foundational material for general fabrication and industrial repair.
