Corrugated metal panels have been tried and tested for decades around the world. One of the first designed metal roofing panels, these systems are also some of the most structural and durable of any panel profile.
A corrugated alloy roofing panel can describe a wide range of looks. A repeating corrugated pattern is all that defines a corrugated metal panel. This type of roofing consists of a metal sheet that is roll-formed into metal panels. These panels are then attached to the roof with screws. The traditional shape of corrugated sheet metal is round and wavy. It is low cost, lightweight, durable, energy-efficient, long-lasting, and easy to install.
This repeating wave creates an incredibly strong panel and is very often used in areas where affordable, yet durable roofing panels are needed. For this reason, you often see corrugated metal panels in tropical hurricane zones, or in high-wind regions.
Corrugated metal roofing almost always uses an exposed fastener system, meaning the screws that hold the panel to the substrate or framing are exposed to the weather. Exposed fastener panel systems are often installed very quickly but do require the occasional inspection (3-5 years) to ensure that the washers are intact and that the fasteners have not loosened over time.
Corrugated roofing panels often have little to no wasted material from the base coil, and do not require slitting down to a smaller coil width. For this reason, a corrugated panel is often less expensive.
