- A36 Hot Rolled Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
A36 Hot Rolled Steel is produced by forming the metal at high temperatures, resulting in a product with slightly rounded edges and a characteristic blue-grey, scaly mill finish. This process makes it cost-effective and easy to work with. Conforming to ASTM A36 standards, it provides reliable strength and excellent weldability using common methods like MIG and stick welding without pre-heating.
As a large-dimension flat bar, this 3-1/2" width provides a solid foundation for applications requiring significant strength and surface area. It is frequently used for base plates for columns, heavy structural bracing, die components, and frame members in transportation and agricultural equipment where durability is essential.
