Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance. Also known as mild steel, low-carbon steel is easy to machine and form. It's widely fabricated into parts that don’t require high strength, such as enclosures, brackets, and mounting plates. All have been manufactured to meet ASTM A653, ASTM A123, or ASTM A108 standards for quality and performance.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
