REMARKS:
gi sheet / galvanized steel sheet is a form of galvanization. It is the process of coating iron, steel, or aluminum with a thin zinc layer, by passing the metal through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements.
gi sheet / galvanized steel sheet is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a “spangle”).
gi sheet / galvanized steel sheet has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc because rust won't attack this protective metal. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component.
