NPU irons are a commonly used structural element in steel structure production. NPU stands for “Normal Profile U,” which is the French equivalent of “Profil U Normal.”

NPU irons are a type of steel profile similar to normal U profiles. However, NPU irons have thicker edges, providing a stronger structure and higher load-bearing capacity. Therefore, they are an important structural element used for constructing higher load-bearing capacity carrier systems.

NPU irons can be produced in various sizes and thicknesses. These elements can be used in many different structures, including bridges, buildings, industrial structures, tunnels, platforms, and roofs. Additionally, NPU irons can be welded, drilled, cut, bolted, and joined using similar methods.

Advantages of NPU irons include high strength, long life, versatility, ease of processing, and being an environmentally friendly material. For these reasons, NPU irons are widely accepted as a commonly used structural element in the construction sector.

Usage areas

  1. Frame and Railings: Rectangular profile is produced in various sizes and is therefore widely used in frame and railing construction. It is preferred for security purposes, especially in areas such as balconies, stairs and terraces.
  2. Roof and Facade Coverings: Rectangular profile is also used in roof and facade coatings. Since it is a durable material, it is resistant to various weather conditions and has a long life.
  3. Rails and Channels: Rectangular profile is also used in the industrial field. It is especially preferred in rail and channel construction. In this way, it facilitates the movement of machinery and equipment.
  4. Furniture and Shelf Systems: Rectangular profile can also be used in furniture and shelf systems. It is preferred in this field as it is both durable and light material. It also provides a modern look.
  5. Automotive and Transportation Vehicles: Rectangular profile is also used in the production of automotive and transportation vehicles. It is especially preferred in body and chassis construction. In this way, the safety of the vehicles is increased and they are made more durable.
