Galvanized Roofing: It is widely used in US for constructing commercial buildings and over homes. It is durable and comes with a long life. It is made of steel and iron as the material for galvanization. In this process galvanize (preferably hot rolled galvanized wire) is heated till hot then the steel sheet (usually hot rolled nha khung thep wire) is placed between the two poles and is twisted and wrapped around. There are various types of the galvanized roofs that includes; slanted, clapboard and flat roof.
As we know that metal galvanized roofing sheet consists of; galvanized steel sheets and iron mesh, and there are also various types of these metals and their properties. Since metal galvanized roofing sheet comes with galvanised wire, and galvanize is galvanized on the basis of hot rolled or cold rolled steel sheets, hence the theoretical weight of galvanised corrugated sheet actually is the mechanical spangle weight before galvanization. The theoretical weight of this spangle is the maximum mechanical spangle weight at its cold point, then after heating it should be cooled down to get the mechanical spangle weight. The mechanical spangle weight of the metal galvanized roofing sheet includes various other factors such as the thickness of the metal, its thickness, its pliability, its ductility and its ability to resist corrosion, and last but not least its ability to abrade.
The process of welding or joining the galvanised steel sheets and the metal is known as galvanization. This process can either be wet welding or dry welding. Wet welding is more commonly used in the fabrication and repair of metal. Dry welding is used for joining thin layers of metal together.
There are various benefits of having galvanized roofing sheets installed on to the roof of your house. First of all, it increases the life of your roof. By increasing its lifespan, it reduces the probability of the roof collapsing due to constant exposure of the external pressure. It also provides protection against rain and snow that may prove damaging by falling debris.
Furthermore, the metal galvanized roofing enhances the aesthetic appeal of the house. Its shiny appearance attracts prospective buyers. Most people consider it to be more durable and strong than any wooden roofing. Further, its aesthetic appeal can be enhanced further by painting or staining it. It has been found to be very resistant to fire and its resistance ability is almost equal to that of rubber and concrete roofing material.
However, the greatest benefit of the galvanized metal roofing is that they are easy to install as compared to wooden roofing. This makes them suitable for smaller areas and for self-installation. You can have them painted or stained to match your home’s color scheme. Also, they are easy to maintain and cost effective.
