Galvanized roofing sheets are available in many different shapes, sizes, and colors. The galvanized roofing sheet, which is also called galvanized steel, can be shaped into various shapes according to the application. But even the thin galvanized roofing sheet form, including the flat bed form, is generally too thin and brittle, even before being formed, so that it tends to be deformed after some time of storage or use, or when exposed to the air. Therefore, it would be advisable to purchase the flat galvanized roofing sheet form at least after having the flat galvanized roofing sheet formed.
A steel sheet having a thickness of up to 0.2mm is generally called as corrugated galvanized steel nha khung thep. A corrugated steel sheet having a thickness of between 0.1mm and 0.15mm is called as corrugated polyester or cpvc. Finally, a corrugated steel sheet having a thickness of more than 0.2mm is called as galvanized steel. The thickness must be selected depending upon various factors like the cost effectiveness, ease of installation, and suitability for your application.
There are generally three types of thickness: the flat, sloped, and rounded gutters. For the flat gutters, the maximum thickness that can be used is not less than one and a half times the thickness of the shingles used for the roof. Hence, a maximum thickness of three and a half times the thickness of the shingles are generally recommended. This ensures adequate protection against flying debris and heat penetration. Thus, such guttering is not advisable for low slope roofs.
For the sloped, seamless or hot-dip galvanized steel sheets, maximum thickness is usually not more than two times the shingles thickness. Thus, this allows for maximum protection from moisture, corrosion resistance, and wind load. This kind of sheet must therefore be made using high quality steel, with a minimum welding. Zinc is typically used for the hot-dip galvanized steel to enhance its corrosion resistance, thermal resistance, and electrical conductivity properties. Thus, you should use this for hot-dip galvanized sheets where possible.
Lastly, in order to determine the appropriate thickness of the galvanized corrugated roofing sheets, you need to measure the entire length of the roof. For that, you need to add four inches on each end. Then, you need to add the thickness of the galvanized corrugated sheet as per the manufacturers’ specifications. This is how the specific thickness of the corrugated sheet is determined. Thicker gauges mean that the roofing is more durable and long lasting.
