NPI

"NPI" stands for "Normal Profile Biplane". NPI profiles are a type of steel profile specified according to a standard profiling system and used in a variety of construction and structural applications.

NPI profiles are produced according to EN 10365, a profile standard used in Europe. This standard determines features such as dimensions, properties and tolerances of steel profiles used in the construction industry in Europe. NPI profiles are often used for beams, columns, frames and load-bearing structures in various structural applications.

NPI profiles have a two-wing structure and generally the upper and lower wings are symmetrical to each other. The profile number refers to the height of the profile in millimeters. For example, the height of the NPI 200 profile is 200 mm. As the profile number increases, the carrying capacity of the profile generally increases.

NPI profiles are known as durable and robust carriers for steel structures and are widely used in the construction industry.
