NPU profile iron is one of the important iron types that is widely used in steel constructions and is also preferred in various sectors and building construction. It is used not only in structural projects but also in many different areas.
In contrast, NPI iron has a more widespread use rate and is generally known as "double-sided NPU". The most distinctive feature of NPI iron is that it has a double-sided symmetrical structure compared to NPU profiles.
Today, the areas of use of NPI profiles are not limited to the construction sector; they are also expanding in spare parts manufacturing, machinery industry and carrier systems. Although NPU iron profiles are preferred in line with increasing needs, NPI irons offer a stronger solution to this need due to their high carrying capacity and double-sided strength.
