Galvanized Sheet

Hot-dip galvanizing is a process in which steel is passed through a zinc bath at a temperature of about 860 °F (460 °C) to coat iron or steel with a thin layer of zinc. 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 dark gray, relatively high-strength material that, in many cases, prevents further corrosion and thus protects The steel below is not affected by the elements. Galvanized steel is widely used in applications where rust protection is required and can be identified by a crystalline pattern of the surface (commonly referred to as "scratch").

In the hot dip galvanizing process, zinc and steel form a metallurgical bond with a range of different iron-zinc alloys. The resulting coated steel can be used in the same manner as uncoated steel. Galvanized steel can be welded; however, the resulting zinc fumes must be handled with care. Galvanized steel is suitable for high temperature applications up to 392°F (200°C). Use at temperatures above this temperature causes zinc to peel off the intermetallic layer. In order to improve the corrosion performance of the exterior panels of some models, galvanized steel sheets are commonly used in automobile manufacturing.

Galvanized steel can be purchased online or at any metal supermarket. It can be cut to your specific specifications.
