Steel curved roof construction details.

Curved roof fascia systems when you want to add a metal curved roof or fascia to your design mbci offers the choice in three distinctive and complete panel systems for your use. Bending and bowing aluminum and steel roofing and siding sheets are rollformed from hardened tempered metal for maximum strength. When curving the beams the curvature had to make a complete 180 degree rotation. Whether the arched roof will be installed over a solid deck or open framing mbci has a panel that fits the application.

The majority of curved steel for use in construction is curved by roller bending which is a cold process. Roller bending involves progressive bending of a section by passing the member through a set of bending rolls. Vertical seam panels unless hand formed or customer curved do not work real well on concave or convex surfaces. When a metal roofing sheet must be installed on a curved roof screws should be installed at every overlapping rib at the sheet ends to resist the natural tendency of the metal to spring back.

Metal should not be re bent once it has been formed nor should it be folded back on itself. When installing the metal panels shown in this booklet over a curved arch the minimum. If a sheet must be bent a gentle 90 degree bend is the maximum recom mended. The standard fastening pattern is permitted over the rest of the sheet.
