- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
A36 Hot Rolled Steel Sheet is produced by passing steel through rollers at high temperatures, resulting in a product with a characteristic dark, scaly surface known as mill scale. This process creates a cost-effective material with looser dimensional tolerances than cold rolled steel, but with exceptional formability and weldability. It meets ASTM A36 standards, ensuring a minimum yield strength of 36,000 PSI for reliable performance.
As a small-thickness sheet, this 18 gauge material is particularly well-suited for applications requiring forming and shaping. It is commonly used for automotive body panels, HVAC ductwork, formed brackets, equipment guards, and general repair patches where structural strength is needed without excessive weight or rigidity.

This mill scale should be removed by grinding, sandblasting, or pickling before painting or powder coating to ensure proper adhesion. For a smooth, paint-ready surface, consider our Cold Rolled Steel Sheet products. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Sheet metal is measured by its Thickness (Gauge) x Width x Length. The gauge number corresponds to a specific decimal thickness.
Example: To order this sheet, specify "A36 Hot Rolled Sheet, 18 Gauge x 48 inches x 120 inches".
