Galvanized roofing is one of the most durable roofing materials available today, and is widely considered “green.” It lasts longer and requires less maintenance than many other types of metal roofing. However, do you know what the advantages of galvanized roofing are?
Galvanized Steel Galvanized roofing can be made from galvanized steel, aluminum, or zinc. It can also be made from aluminum, copper, or zinc that has been treated with a coating of zinc nha khung thep. The galvanized coating actually separates the galvanized steel from the air, providing it an extended lifespan, up to 60% more than traditional galvanized metal roofing sheets. Even though the galvanized coating is thicker, not all layers are equally protected. The thickness of the zinc coat increases the overall thickness of the galvanized sheet.
Galvanized roofing does not only have its benefits when it comes to durability and long-lasting roofing. In addition to the galvanized layer, the sheet also has several other layers of packing. The higher the packing density of the zinc or aluminum layer, the higher the load-bearing capacity (FLD). A higher FLD means stronger, less wear-and-tear and less frequent replacement.
Packaging helps to reduce the amount of corrosion the metal experiences, so it will resist rust damage over time. One of the layers of zinc is a high-tension layer; the other layers are low-tension. The combination of high-and low-tension layers gives the sheet a distinct hot-dip galvanized appearance. Hot dip galvanized are also referred to as “hot dip galvanized,” since they receive a hot dip treatment just before they are packaged. The term “hot dip” refers to the process by which hot metal ions pass through an electrically ionized coating, creating a coating with a reddish-brown color.
The galvanized roofing thickness is measured in millimeters read gi or in inches red gi. The thickness of a galvanized roof is an important factor to consider when choosing a metal for installation. Generally, the thicker the galvanized roofing, the more durable it is. Roofs with a thickness greater than 40mm read gi will be stiffer and more durable than those with a thinner thickness.
When checking for the appropriate thickness, it is important to use a ruler or spreadsheet to determine the corrugated width. The standard thickness is 0.2 mm, which is the minimum recommended for standard installations. Other gauges will be closer to the actual thickness that is installed, but they will not be as durable. For best results, install a full hard corrugated panel at the very edge of your roof, and then cut it with a saw. A cross sectional sample panel should be taken to determine the width.
