Galvanized Steel Sheet - 20 Gauge x 48" x 120"
This 20 gauge galvanized steel sheet measures 48" x 120" and meets ASTM A653 standards. The hot-dip zinc coating provides a durable barrier against rust and corrosion, making it ideal for outdoor applications like roofing, flashing, and signage. In stock Los Angeles.
- Galvanized Steel Construction
- ASTM A653 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Corrosion Resistance
This 20 gauge sheet is a carbon steel product coated with zinc on both sides through a continuous hot-dip process, conforming to ASTM A653. This protective layer creates a strong metallurgical bond that prevents rust and corrosion. It combines the formability and strength of steel with the long-term durability of zinc, making it a cost-effective solution for exposed environments.
As a small-thickness sheet, this 20 gauge material is easily formed, bent, and cut. It is perfectly suited for applications requiring lightweight durability, such as HVAC ductwork, formed brackets, electronic enclosures, weather flashing, and custom signage where corrosion resistance is a primary concern.

Finish Options
This product comes standard with a hot-dip galvanized finish, which typically has a crystalline, spangled appearance. The zinc coating provides both barrier and sacrificial protection against corrosion. For painting, the surface must be properly cleaned and primed. Contact our Los Angeles sales team for information on minimally spangled or galvannealed finishes for special orders.
How to Measure
Sheet metal is measured by its Thickness (Gauge) x Width x Length. Gauge is a standard thickness measurement; use calipers for a precise decimal reading.
Example: To order this sheet, specify "Galvanized Sheet, 20 Gauge x 48 inches x 120 inches".
