Folded plate roofs are assemblies of flat plates that are joined together along their longitudinal edges. The way they are connected allows them to carry loads without needing additional support beams along the edges. These roofing systems are chosen by property owners for their durability and high weight-bearing capacity.
The first roofs originated in Germany during the 1920s; they were constructed for massive factory buildings. They became popular in Russia and North America during the 1930s. It was mainly used for the construction of warehouses back then, but it’s now the preferred solution for commercial buildings, large industrial structures, and even mid-century modern homes.
