Unic Rotarex European certification done with Tuv sud MunchenEuropean Certification


What more can we say about us rather that we produce under the European certification mark, and we have implemented a production control system audited by the most renowned  European certification company, TÜV SÜD München? Nobody in Europe doubts the quality of products accredited by TÜV SÜD.

ISO9001 quality for light steel structureISO 9001 quality


We believe that this is the biggest question asked by someone who wants to produce something. We have shown through many of the products that we can obtain quality at a low price, and we have implemented the quality control management system with TÜV SÜD München, which does not need further presentation.

If you follow our evolution graphics, you will see all indicators are growing each year and if you will compare us with the ones that call themselves “competition” it is clear that you will understand enough about us and our attitude about what we do.

The mission of the company

Unic Rotarex® is on the market for over 24 years, and it has always taken the mission to develop constructive systems based on lightweight steel structures. In the beginning, we did interior designs, gypsum partition walls, and decorative elements of gypsum boards with lightweight steel structure. Then our company’s mission became taking light structures to the next level. We built the first house with “U” and “C” galvanized profiles. Today the mission of the company has achieved its purpose. We developed the best constructive systems with lightweight steel structures, a modern fabrication flux, and we design the most performant products. We don’t think that anyone can contest this.

The purpose of the website

The purpose of the website rotarex.ro/en is developing constructive systems based on lightweight steel structures. When you say “Rotarex,” you say “lightweight steel structures,” the brand has achieved its initial purpose. Of course, we live in the “copy-paste” era, but the ones who read all websites in this niche realize that the first idea appears at Rotarex, and then it is taken over by all the others in various forms. We would say that the site has achieved its purpose because the experience does not allow competitors to do anything other than to modify the way that we have imprinted over time.

Who recommends us?





“FORESTS ARE SAVED WHILE STRUCTURES ARE MADE!” is the motto under which we describe ourselves ecological, is the motto under which Unic Rotarex® proposes a new ecological concept.

The need to change our way of thinking and use wood only for the aesthetic elements of the building.
The steel is recyclable if we melt our old cars and turn them into house structures, we get a double ecological effect. Or do you think it is ecological to cut our forests and make houses?

Who we are?

Romanian speaker, flag of Romania German speaker, flag of Germany English speaker, flag of England

Graduate of the Faculty of Management in Brasov – Management specialization.

Over 20 years of experience in the LSF field, first years in Germany, and over ten years in Romania.

The experience gained in the German construction sites where I built only lightweight steel structures (compartment walls) made of galvanized profiles has put the mark on my way of thinking about how construction should look like.
When you learn to work by millimeter, you understand that no compromise can be made.
When you learn to stop compromising and go back to Romania, it is challenging to respect what you have learned in Germany. Most give up!
I have found a way not to compromise, to work precisely, and to have satisfaction right here in Romania. Every millimeter you give away at the beginning of the construction, you must recover at the end, and surely it will be harder and more expensive to do.
Our structure is plane, and whatever you put on it will remain so and will be so right from start to finish and will be simpler, faster, and cheaper. What about this philosophy ?!
We take our clients from the internet and our greatest pride is that none of our clients have so far expressed any dissatisfaction regarding our collaboration or the product received. On our website we can write anything, the internet is not ours, we can not censor it. Be aware that the ones who say bad things about us, because:

-what we can say about us – is not much, but shown through the people and their accomplishments;

-what competition says about us – means nothing, but shows that we are in their way;

-what our customers say about us  – is a big deal because it shows our realizations.
