Metal roofing, being one of the oldest types of roofing, has been used for centuries to provide waterproofing and architectural appeal for commercial buildings of all kinds.
While metal roofing was originally manufactured and fabricated from metals such as lead or copper, technology has evolved in the modern era where metal roofing panels are fabricated from equipment resulting in thicker metals fabricated from steel and aluminum.
Metal roofing systems are separated into two categories of application: architectural metal roofing, where the metal roofing is installed over a substrate, and structural metal roofing systems, where the panels are designed to be installed over open framing, where engineering and spanning characteristics are taken into consideration during the design phase of a project.
Metal panels are also installed as cladding systems on the exterior of buildings, whether installed as a wall cladding panel, a screen wall panel, or a mansard panel application.
Metal panels used for roofing and cladding can be specified in flat, standing seam, batten seam, trapezoidal, and flush interlocking panels.
