NPI – NPU – HEB – HEA Structural Steels

What is HEA Steel Profile

The HEA series of steel profiles represents a wide range of rod-shaped structural elements with parallel inner surface of flanges and dimensions according to EN 10365. Product tolerances are defined by EN 10034: 1993. The HEA series steel sections can be combined with a stainless steel beam, then welded or bolted or hot fabricated, then hot rolled or extruded.

The lower and upper horizontal part of the beam is called flange, and the vertical middle part of the connection is called web. The most common version in this product line is the HEB series, followed by the HEA series.

HEB Irons

Steel construction structures are the type of building that has been preferred especially in recent years. Steel construction structures are structures that are placed on a system made of profiles made of steel, and are supported to stand with the help of columns and beams. Steel structures, which guarantee use for many years, have started to be used in many areas. Thanks to the ease of installation, the structures that can be delivered in a short time have begun to go beyond traditional construction methods.

Ideal Use for Earthquake Zones

Steel construction structures have been preferred for use especially in earthquake zones in recent years, since they are particularly durable and generally single-storey structures. The fact that Turkey is an advanced and moderate earthquake zone and that steel construction structures can be used for many years thanks to their durability, has led people to start to turn to these structures. Architectural and engineering wonders are created in the production of steel construction structures. Thus, steel construction structures, which are established much faster than the houses built in traditional structures, are one of the elements that facilitate the choice of people. In addition, steel construction structures are installed at a much more affordable price compared to traditional structures. It provides a life guarantee of up to a hundred years in steel construction structures, which are much easier to install.

Heating in Steel Structures

There are questions such as how to warm up in people’s minds for steel construction structures. One of the most important features of steel construction structures is that the insulation of the structure is done very well. Thus, it provides heating in a very comfortable way in steel construction structures without heat loss. Steel structures, which are widely used in different areas, show themselves in institutions such as schools, factories and workshops outside the home. Thanks to its easy and fast installation, steel construction structures are preferred by people.

HEB iron from 100 millimeters up to 1000 millimeters For steel structures, 100 millimeter HEB irons have a body thickness of 6 millimeters, a sidewall thickness of 10 millimeters, a corner thickness of 12 millimeters, and a weight of 400 kilograms / meter. HEB irons, which also have different weights, are among the most used profiles among the building profiles. Thus, it has the feature of being used safely in steel construction structures. HEP profiles are indispensable parts for structures made of steel. Since the entire structure is on the profiles in steel construction structures, the steel profiles must be extremely durable and useful. Therefore, HEB profile irons can be produced by Lavi Metal in different weights and sizes and can be used functionally in steel construction structures.

Different Uses of Heb Construction Irons and Cayirova Profile

HEB structural irons are one of the irons in the profile group. It is used in almost every stage of steel construction structures. In addition, HEB construction iron is a type of iron that can be used in the manufacture of agricultural machinery, the automotive industry and the sub-industries of the automotive industry. The kilogram price of iron in HEB construction irons; The size of the iron can vary according to its size and can be at different prices. HEB structural irons, which are used in all areas of steel structures, are indispensable for steel structures. HEB construction irons can be supplied in desired dimensions from Cayirova Profile company.

NPI Irons

Today, with the development of the building industry, the spread of constructions and the development of the industry, the need for raw materials and materials that can be processed has increased. Companies want to complete their projects in a short time, cost-effectively and with a long life. That’s why they often use up-to-date technology in these projects. They also need materials that will facilitate their work in strengthening their structures, reducing their costs and shortening processes. One of the materials that have these properties today is NPI irons. Thanks to the great advantages it provides to companies, they always prefer to complete their projects.

What is NPI Iron?

NPI irons are produced by hot rolling method to give high level of strength. As it can be positioned horizontally or vertically, its intended use is generally to provide support for carrying large loads. In addition, it is frequently preferred in other sectors where heavy load support is required. These supports made of steel provide great freedom of use as it is possible to shape, form, weld and machine them. In addition, since it can be used as a spare part, it is very useful for companies engaged in production and maintenance.

Properties of NPI Irons

This product, which is obtained by special processing of steel, is also called industrial iron. Since its dimensions can be designed according to the project, it offers a wide range of use to manufacturers. It helps to increase the strength of the system in which it is used and to extend its life. They are also very resistant to external factors. That is why their use is so common in daily life. These profiles are qualitatively of the highest quality.

NPI Iron Usage Areas

The usage areas of these parts, which are produced to support heavy loads in construction and industry, are also quite wide. For example, they are actively used in load-bearing legs of skyscrapers, energy transmission lines, bridges, dams and roads, as carriers and supports, and in crane production. However, it is used in every environment where steel construction is used, to add strength and durability to the structure. As you know, such structures are expected to be long-lasting and durable. For this reason, companies use NPI irons to increase the durability of their structures as well as extend their life.


They are used not only in steel structures, but also to increase the durability of almost all reinforced concrete structures. They are preferred for adding power to the system in newly built houses and constructions to be renovated. For these reasons, this material is widely used in various parts of strong structures.
