This type of corrugated iron can be used for both ordinary pitched and low-slope roofs. It can be used at small inclination angles, because it has a capillary groove under the connecting lock, and it also has a large bearing capacity, so when properly mounted, it will cope perfectly with any snow and wind loads. The PK-57 corrugated sheet is used for wall and panel fences, floors with large spans (up to three meters), and as a fixed formwork in monolithic frame construction.

It is the most commonly used corrugated iron in steel designs of metal buildings and metal frames for any climatic zones. Made of high-quality rolled metal,
the load-bearing PC-57 roofing corrugated sheet of galvanized steel will be an indispensable aid both for creating intermediate floors and for creating load- bearing walls of buildings that have no (or minimal) additional metal structures. Without the use of the PC-57, it is impossible to imagine the construction of prefabricated structures: it has excellent indices when it comes to the difference between full and effective width, and also the lock is quite reliable and will not create any additional problems during installation.
