The zinc protects iron by corroding first.

Gi sheet metal properties.

Corrugated metal made from galvanized steel or galvanized iron gi are the common materials available but it s also available in other metals like aluminum and copper which are a more expensive option. N mm2 or mpa the symbol is σb. Type of rolling operation hot rolling or cold rolling operation also has an impact on sheet metal material properties. Material selection is done based on product functional requirements by looking at material physical and mechanical properties.

The zinc coating when intact prevents corrosive substances from reaching the underlying steel or iron. Sheets of metal beyond a few micrometres in thickness appear opaque but gold leaf transmits green light. It is the maximum stress that the sheet metal material is subjected to before pulling out. Galvanizing protects the underlying iron or steel in the following main ways.

In terms of optical properties metals are shiny and lustrous. Metals in general have high electrical conductivity high thermal conductivity and high density. Following are some of commonly. Galvanized iron gi sheets are steel sheets which are basically coated with zinc and include a range of hot dip galvanized and electro galvanized steel sheets.

Zinc weathers at a very slow rate so the coating generally has a long life. Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing sponsored links wire gauge is a measure for the size of a wire either in diameter or in cross sectional area. It is the maximum stress that the cross section is subjected to when the load is applied between the two points of the specimen. Gi sheets find uses in every sector of the economy from agricultural to industrial and constructional activities.

Various sheet metal material grades are available in the market.
