Corrugated Metal Roof Panels
Corrugated Metal Roof Panels Can Be Used To Cover Diverse Structures
Roofing is an essential for protecting buildings from the ill effects of weather, and corrugated metal roofing is an alternative that is in extensive use. The panels can be used over large buildings and do not add much to the weight of the roof, thus allowing for lighter roof structures.
Corrugated metal roof panels come in different shapes and sizes and it is these corrugations that give the panels additional stiffness and allow them to span larger distances. Corrugations can be in the form of waves or have a squarer configuration that is known as Trafford. These metal roofs have a high resistance to wind and rain and all outdoor conditions. The greatest advantage of metal roofing is that it can be recycled and reused, and requires very little maintenance throughout its long life.
Metal Roofing Can Be Galvanized Or Coated
Metal roofing can be galvanized or coated to give it extended life and prevent it from rusting. Any metal exposed to the weather will corrode and this coating or galvanizing can help to retard this process. You can also buy corrugated metal roof panels in a number of colors and this allows them to fit in with any architectural roof design. Metal roofing is very commonly used over industrial structures. These roofs can get hot and it is necessary that proper arrangements are made for ventilation to create comfortable working conditions. It is also possible to get these panels with insulation and such panels can be seen in the walls and roofs of cold storages.
Corrugated metal sheets are made in definite lengths and widths and to cover a roof. Adjacent panels are overlapped to a certain width or length so that it forms a continuous surface. A single corrugation is overlapped in width while 6 to 9 inches is overlapped in length. It is also customary to allow the metal sheets to overhang the eaves portion so that any rain or snow runoff will not run down walls. It is also possible to install gutters at these edges so that any rain runoff is properly guided down to drains and other devices.
While fixing these metal corrugated the holes through which screws or nails are fixed must be on the ridges of the corrugations, so that rain water can run down easily. It is customary to use felt or other washers on these fixtures so that the holes get sealed and do not become a point of ingress for rain water.
It is important to know accurately the position of purlins that will support the roofing panels, so that holes, that are often pre-drilled are in the correct location. J Hooks and other types of fixtures enable the sheet to be fixed firmly to the sheet and purlins.
It is often necessary to install ridges or metal caps over places where metal roofing meets at an angle. These are made from plain metal sheets and can also be shaped to fit over corrugations. Metal roofing can be used to cover almost any sort of structure.
