Investigation of Standing Seam Metal Roofing

摘要

The Army has used metal roofing systems for many years with great success. In the past, flat sheets were fabricated and seamed by hand at the jobsite. Recently, however, several new systems have been developed for which metal panels are prefabricated, shipped to the construction site, and assembled using new techniques. Current Corps of Engineers Guide Specifications are outdated with respect to these new products. The design and method of application differ among products; still, any system to be used in Army construction must meet critical design criteria. In particular, the system as applied must allow for thermal expansion and contraction with changes in ambient conditions, and the Guide Specifications will have to be edited to reflect this. This report compares the features of several metal roofing systems on today's market.
