Thin-sheet purlins are produced by cold rolling from the zinc-coated leaf of steel. Features Are used in front and roof structures as an auxiliary and carrying material. The most widespread product for the installation of sub-constructions for a wall fencings and coatings, and also auxiliary carrying systems. In comparison with ferrous metal have lighter weight and are more technological in use.
