- A36 Carbon Steel Construction
- ASTM A36 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability
A36 Hot Rolled Steel is a low-carbon structural steel with good overall mechanical properties, making it a go-to choice for general purpose applications. Formed at elevated temperatures, it has a characteristic scaly, blue-grey mill finish and slightly rounded edges. This process makes the material cost-effective and easy to fabricate using common methods like welding, cutting, drilling, and forming, conforming to ASTM A36 standards for reliable performance.
As a medium-sized bar, this 2-1/2" width provides a balance of strength and versatility. It is perfectly suited for applications requiring robust support without excessive weight, such as structural bracing, wear strips for machinery, equipment base plates, and chassis components for trailers and vehicles where weldability and durability are critical.
