Marlon Polycarbonate F Profile Aluminium has a durable aluminum construction that ensures stability and longevity while enhancing the overall appearance of the roofing system. It is ideal for both residential and commercial applications, providing reliable performance and a sleek finish. The F Profile is designed to be used in conjunction with polycarbonate sheets, which can be used for a variety of applications such as patio covers, pergolas and canopies, lean-to's and conservatories, wind screens, car ports, vertical glazing, and veranda covers. To use the F Profile, trim the edge of the final panel to fit inside the side profile, then fit the side profile over the trimmed edge of the sheet and secure to the end of the purlins with screws.
