All that you need to know about PPGI sheets
Low rise metal buildings have become a quintessential part of a typical urbane landscape. More often than not, these buildings are made up of PPGI sheets. PPGI stands for pre-painted galvanized iron. These sheets contain almost 55% aluminum. The sheets are primarily zinc coated iron, thus have a lifespan of 20 years and more.
Characteristics of PPGI sheets
When the sheets are manufactured, they are dipped in a hot metallic coat. The sheets are coated with zinc, aluminum, magnesium as well as iron. These coatings make the sheet resistant to corrosion. PPGI sheets are known for their longevity, and that is imparted to sheets by the coating of zinc. A strong deterrent to damage by abrasive and extreme weather conditions, the sheets get this property because of the amalgamation of a number of metals. One of the most attractive qualities of these sheets is that they are lightweight, thus easy to carry over long distances.
Where are they being used?
Given their extremely useful and attractive features, PPGI sheets are being used everywhere. They have risen to become the best roofing sheets for housing. They are an ecologically friendly alternative to other materials, such as wood. Wood may also become infested with termites or may become weak due to extreme weather conditions and rains, but that is not the case with PPGI sheets.
Another beneficial feature of these sheets, longevity and durability, makes them the first choice for using in construction. These sheets are a modern alternative to traditional elements, which are heavier, more difficult to handle and do not contribute to saving energy. From construction to housing to industries to mining and more, PPGI sheets have made a name for themselves in every field.
Pre-painted sheet coating process considerations
Known for their long lasting nature, this feature can be mainly ascribed to the layers of coatings that are applied on the sheets. The coating process should be conducted properly, so as to ensure good paint adhesion, which reduces the chances of blistering or delamination. Some practices that are considered to contribute to controlled sheet coating are:
• Surface of the sheet should be adequately clean before application of the first layer of coating
• Good quality pretreatment should be applied, suitable for end use
• Thick layer of primer and topcoat should be applied
• Essential thermal curing of paint and primer
Pre painted galvanized iron sheets have been in use for decades in all sorts of climates. A well manufactured sheet can last for a lifetime, given that it is properly installed and adequate efforts are made to maintain it.
