G90 galvanized sheet refers to steel sheet coated with zinc using the hot-dip galvanizing process, with a coating weight of 0.90 ounces of zinc per square foot (total both sides) or 275 grams per square meter (total both sides). The “G” stands for galvanized, and “90” represents the coating weight.
Key Properties of G90 Galvanized Sheet
- Corrosion Resistance: The primary benefit of G90 is its superior resistance to rust and corrosion due to the thick zinc coating. This makes it suitable for outdoor applications and harsh environments.
- Durability: The zinc coating provides a sacrificial layer, protecting the underlying steel from degradation.
- Formability: G90 galvanized sheet can be bent, stamped, and formed without significant damage to the coating.
- Weldability: While welding galvanized steel requires special techniques to address zinc fumes, it is achievable.
Applications of G90 Galvanized Sheet
G90 is commonly used in:
- Construction: Roofing, siding, gutters, and structural components.
- Automotive: Body panels and undercarriage parts.
- Agriculture: Livestock equipment and storage bins.
- HVAC: Ductwork and ventilation systems.
- General Manufacturing: Various fabricated parts requiring corrosion protection.
Considerations When Using G90 Galvanized Sheet
- Cost: G90 is generally more expensive than lighter galvanized coatings due to the higher zinc content.
- Weight: The thicker zinc coating adds to the overall weight of the sheet.
- Surface Appearance: The coating may have a spangled appearance, which may not be desirable for all applications.
