Steel structure houses made by Unic Rotarex® technology


Steel houses by Unic Rotarex® technology New lightweight steel structure house technology revolutionizes classic masonry house construction and improves timber framing house technology. Steel houses with galvanized steel structures, designed and produced in the factory in a very simple and efficient modular system. Unic Rotarex® steel houses reduce the price by a minimum of 25% and the construction time by less than 50% compared to traditional constructions. We design, manufacture and assemble light steel structures made of galvanized steel. We develop steel house technologies, adapted to the most difficult thermal, seismic, and humidity conditions.
The steel house structures produced by us are CE marked and audited by TÜV SÜD München.
By buying steel houses from us, you benefit from free and complete online advice, both during the design period and during construction. Unic Rotarex® steel homes, a simple, fast, and economical technology.


Steel houses’ price is the most sought after by those who are interested. However, you have to understand that in order to give a price we have to refer to a certain construction.
The prices refer to the design, production, and assembling of the steel structure.

When you have an architectural project or a clear sketch of what you want to build, send a request and you will receive the price estimate by email, as soon as possible. It is possible that we contact you for details, as we can be able to draw up the most accurate offer.


The steel houses construction technology developed by Unic Rotarex® is based on many years of experience, and hundreds of houses built.
In our country, all seasons are extreme. The house must be equally protected from cold, heat, humidity, wind, or earthquakes.

We designed inexpensive wall sections using site-specific prefabricated materials. Below are technical sections with increased thermal, sound, and fire resistance. If your architect consults with us, and you respect the project, you can get a considerable price reduction.

Types of sections

Types of standard sections for steel houses:

Thermal resistance

The thermal resistance of Unic Rotarex® steel houses.

Fire resistance

The fire resistance of Unic Rotarex® steel homes is achieved by cladding with fire-resistant plasterboard.
Knauf board solution with 30, 45, 60, 90, 120, and 180 minutes resistance.

Acoustic resistance

Acoustic insulationAcoustic resistance in walls can be improved in several ways:

  • Knauf soundproofing in the wall and plasterboard cladding (see details)
  • Cork cladding on interior walls
  • Two parallel walls that do not touch and do not transmit their vibration. Recommended only between the master bedroom and children’s room, for duplex houses or hotel rooms.

The acoustic resistance of the floor can be improved by using soundproofing boards instead of extruded polystyrene between the screed and OSB.

Seismic resistance

Seismic resistance is easy to solve due to the low weight of steel constructions compared to classical buildings.
Earthquake is an acceleration of the Earth’s crust horizontally, which is multiplied by the much smaller mass of our buildings, meaning that they successfully resist large and very large earthquakes.

Wind resistance

The wind resistance of Unic Rotarex® constructions of up to 150 kilometers per hour is achieved under standard price conditions.
We can also design for higher wind intensities. The elasticity of the steel structure puts our buildings in a superior position in fighting the wind.

Corrosion resistance

White corrosionCorrosion resistance is solved by using galvanized steel
Corrosion protection must be for the standard 98-year lifespan, according to the law.
Galvanizing is recognized as the best corrosion protection solution for steel homes
We use galvanized steel, with zinc levels between 150-275 grams per square meter, depending on the location of the construction and the construction conditions.
It is important, between delivery and assembling, to store the steel structure according to our instructions. However, if you notice spots of this kind (white rust), there is still no need to get impatient, as galvanizing has the great property of self-cleaning.
The assembled steel structure will dry quickly and such stains can only occur from improper storage.



The design of the steel structures is done only by specialist engineers approved by Unic Rotarex®. We can intermediate the MLPAT verification.


Production is made out on a production line composed of last-generation CNC machines. All our products are CE-marked.


The assembling consists of the pre-assembling of the structural elements, which happens in the factory, and the assembling on-site, done by our collaborating teams.


We can arrange the transport, you make the order and payment.


After buying an Unic Rotarex® steel home, you benefit from free consultancy, by phone and by other media, during the assembling and during the other construction phases.

  • ISO 9001 – quality management translated into concrete working procedures.
  • CE marking – factory production control according to SE1090-1.2, materialized in work instructions.
  • Declaration of performance – is the document that certifies the performance of the product.
  • Quality certificate – the document that certifies the quality of manufactured products.
  • Warranty certificate – the document that certifies the warranty of the purchased products.

Our portfolio includes several hundred steel homes. You can see more on the website.
