    Corrosion-Resistant Low-Carbon Steel Sheets

    Image of Product. Front orientation. Steel. Corrosion-Resistant Low-Carbon Steel Sheets.
    These sheets are treated 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.
    Aluminized Low-Carbon Steel—Coated with an aluminum-silicon alloy, these sheets resist corrosion while withstanding long-term exposure to higher temperatures.

    Paintable Low-Carbon Steel Sheets

    Image of Product. Front orientation. Steel. Paintable Low-Carbon Steel Sheets.
    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.
