Hot-dipped galvanized commercial steel is a carbon steel sheet coated with zinc on both sides through a continuous hot-dip process. This method forms a durable iron-zinc alloy bond, providing excellent corrosion resistance and long-lasting performance.

Galvanized steel is among the most economical options for corrosion-resistant sheet metal and is well-suited for a wide range of architectural, industrial, and fabrication applications. It can be roll-formed, brake-formed, lock-seamed, riveted, spot-welded, or soldered.

Galvanized Commerical Steel by Quality Metals

General info

  • Available Gauges: 20 GA, 22 GA, 24 GA
  • Standards: ASTM A653 / ASTM A924
  • Coating Weight: G-90 (0.90 oz/ft² total, both sides)
  • Surface Treatment: Chem-Treat Dry

Coating Thickness

Coating weight is measured in ounces per square foot.
Designation G-90 indicates a minimum of 0.90 oz/ft² of zinc coating,
applied equally on both sides of the sheet for enhanced protection against corrosion.

ASTM Specifications

  • ASTM A924: Governs general requirements for carbon steel sheet metal coated by the hot-dip process, including tolerances on thickness, width, camber, and shape.

  • ASTM A653: Covers requirements for the galvanized coating, including chemistry, mechanical properties, and coating weights for various grades.

Mechanical Properties (Typical)

  • Yield Strength: 48 ksi
  • Tensile Strength: 59 ksi
  • Elongation: 28%
  • Hardness: 62 Rockwell B

Key Features

  • Superior galvanic protection.
  • Fabrication-friendly (roll-formed, brake-formed, lock-seamed).
  • Compatible with welding, spot welding, riveting, and soldering.
  • Resists “white rust” during storage and transport thanks to Chem-Treat Dry coating.
  • Ideal for architectural, industrial, and general-purpose applications.
