- Galvanized Steel Construction
- ASTM A653 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Corrosion Resistance
Galvanized steel sheet is a carbon steel product that has been coated with zinc through a continuous hot-dip process. This creates a metallurgical bond between the steel and zinc, providing a durable barrier that protects against rust and corrosion. The material combines the formability and strength of steel with the superior protective qualities of zinc, conforming to ASTM A653 specifications for reliable performance.
As a thin 18 gauge sheet, this material is easily formed, cut, and fabricated. It is an ideal choice for lightweight applications requiring long-term durability in moist or outdoor environments, including formed brackets, electronic enclosures, shims, and custom HVAC components.
