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, form, and weld. It's widely fabricated into parts that don’t require high strength, such as fixture clamps, mounting plates, and spacers.

High-Temperature Aluminized Low-Carbon Steel Sheets
- Yield Strength: 30,000 psi
- Hardness: Not Rated
- Heat Treatable: No
- Specifications Met: ASTM A463
Coated with an aluminum-silicon alloy, these low-carbon steel sheets resist corrosion while withstanding long-term exposure to high temperatures. Low-carbon steel, also known as mild steel, is easy to machine, form, and weld. Use these sheets in drying ovens, furnaces, and smokestacks.

Paintable Galvannealed Low-Carbon Steel Sheets
- Yield Strength: 30,000 psi
- Hardness: Not Rated
- Heat Treatable: No
- Specifications Met: ASTM A653
The galvannealed coating allows these low-carbon steel sheets to be painted without prepping the surface. They're easier to weld and more scratch resistant than zinc-galvanized steel sheets. Low-carbon steel, also known as mild steel, is easy to machine and form. Use these sheets for outdoor signs, cabinets, and doors.
