NPI NPU PROFILES
(NPI) / UNP (NPU) Profiles; steel profiles are used in the construction of industrial constructions and steel construction weighted structures.
Although they have different fields of use, NPU and NPI irons, which are frequently needed in construction, machinery and bearing structure elements and are important building materials, manufactured in different sizes using hot rolled raw materials in S235JR (ST37), S275JR (ST44) and S355JR (ST52) qualities.
NPU and NPI irons, which are manufactured in standard 6 meters in small sizes and in standard 12 meters in large sizes, can also be manufactured in different lengths according to special order.
You can contact our sales team for more detailed information about NPI and NPU irons.

Physical Properties
S355J2 is a micro alloy structural steel. mechanical engineering applications. Steel has good weldability with a maximum CEV = 0.47 for all variants. The steel can be delivered with a controlled silicon content for good galvanizing properties. Below are a number of closely related variants with various impact strengths.
The S355J2 steel grade is characterized by an optimum set of mechanical properties, which determines its widespread use when producing metal structures and products for construction and machine building. It is used in industrial and civil engineering, as well as in the construction of oil and gas platforms, other offshore structures, power transmission towers and other metal structures. S355J2 steels are actively used to manufacture elements of heavy ground and underground equipment (bulldozers, excavators and dump trucks), railway wagons and agricultural machinery.
