Plain bars, with their smooth and even surface, are a type of plain steel used primarily in structures such as roofs, floor slabs, and parking lots. Thanks to its elastic structure, it can flex under a certain load and absorb energy. It is preferred in structures exposed to static loads, such as factories and buildings, due to its load-bearing capacity. Plain bars are notable for their ease of installation and cost-effectiveness. Furthermore, by providing a suitable base for operations such as plumbing installation, it accelerates construction processes and provides material savings.
