It is time to learn about corrugated metal roofing. In short it is type covering made of cold-bent steel sheet profiles with a wavy form. The corrugated sheet is mostly made of galvanized steel with a polymer coating, but can also be produced out of aluminum and stainless steel. The panels are fixed by exposed fasteners, which is both – the system’s strength and its weakness. On the plus side the drilling allows the installation to be quick and easy. On the other hand, each sheet requires approximately 20 screws to be secured properly. The holes for the screws reduce water-resistance of the roof and make the covering susceptible to leakage.
The system is simple and cost-effective. You can often see it in agricultural or construction areas: on industrial buildings, barns, commercial and pre-engineered structures.
