Galvanized Corrugated Steel Sheets for Walls

Specifications

   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.

Packing

Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential, the contact points of these bands on the coil edge to be protect with edge protectors. Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance, and two-four such bands securely tied around belly of coil at about equal distance.
