20 Ga Hot Dipped Galvanized Steel Sheet Metal

Galvanized steel angle is a a36 hot rolled mild steel angle that has been hot dipped in a zinc rich galvanizing process.

20 ga hot dipped galvanized steel sheet metal. It has great conductive properties and does not discolor or absorb finger prints. Galxc is a hot dipped galvanized sheet metal product that has a coating weight under g 30. Metals depot stocks many sizes in precut sizes full mill sizes or we can hot dip virtually any. It is a coating thickness designation in the galvanizing specification astm a653.

The sheets have been continuously hot dip coated with a protective layer of zinc and can be formed without peeling or flaking. When exposed to the atmosphere pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate a dull grey fairly strong material that stops further. The typical corrosion free life of our g90 galvanizing process is about 20 years. A wide variety of 20 ga galvanized sheet metal options are available to you menu.
