UNIC ROTAREX® STEEL HOUSES
Steel houses made using Unic Rotarex® technology. A new lightweight steel frame housing technology that revolutionizes traditional masonry house construction and significantly improves wood framing systems. These steel houses are built using galvanized steel framing, designed and manufactured in a modular system that is both simple and efficient. Unic Rotarex® steel houses lowers construction costs by at least 25% and reduces the building time by over 50% compared to conventional methods. We design and produce light steel structures made of galvanized steel sheets and offer support for their assembly.
We develop steel house technologies tailored for the most challenging thermal, seismic, and humidity conditions.
Our house structures are CE marked and audited by TÜV SÜD Munchen.
When you choose our steel house structures, you benefit from complete and free online consultancy, both during the design phase and throughout the construction process.
Unic Rotarex® steel houses – a simple, fast, and cost-effective technology.
STEEL HOUSE PRICES
You need to understand that in order to provide you with a price, we must refer to a specific construction.

TECHNOLOGY
The steel house developed by Unic Rotarex® is based on many years of experience and hundreds of steel houses built.
In our country, all seasons are extreme. The steel house must be equally protected against cold, heat, humidity, wind, and earthquakes.
We designed economical 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 design, you can obtain a considerable reduction on the final price.

FAQ - FREQUENTLY ASKED QUESTIONS
STEEL FRAME HOUSES VS. BRICK HOUSES
Steel framing generally offers faster construction, a cleaner building site, high precision, and an excellent strength-to-weight ratio. Both steel framing and brick can be durable and energy-efficient when properly designed and constructed. The right choice depends on the project, technical requirements, and construction objectives.
IS A 1MM STEEL THICKNESS ENOUGH?
Sheet thickness alone does not determine the strength of a steel structure. Strength depends on the profile shape, geometry, arrangement of the elements, connections, and, most importantly, the structural design calculation, which determines the appropriate solution for each project.
PRICE PER SQM FOR STEEL FRAME HOUSE
The price per square meter for a steel frame house can vary significantly depending on location, materials, design, labor costs, and workforce availability. In most cases, this price does not include the foundation, land, installations, or finishes, while turnkey offers are usually more expensive because the builder assumes all project risks. For a more accurate price, it is recommended to request separate quotes for the structure, materials, and labor.
STEEL FRAME HOUSES VS. WOOD FRAME HOUSES
Lightweight steel framing offers precision, strength, fast assembly, and long-term stability, while also being recyclable. Unlike wood, steel is not affected by moisture, warping, or pests and allows for industrialized construction based on precise 3D plans. This makes steel framing a modern, efficient, and durable alternative to wood framing.
DISADVANTAGES OF STEEL FRAME HOUSES
Aspects such as fire protection, thermal and sound insulation, and long-term durability can be optimized through modern technical solutions and high-quality materials. This construction system allows for efficient, durable homes that meet today’s standards and requirements. With proper design and execution, steel frame houses can outperform many traditional construction systems.
STEEL FRAME HOUSES – CUSTOMER REVIEWS
Light steel frame houses are highly valued by customers for their fast construction process, durability, energy efficiency, and excellent value for money. Reviews received from clients around the world highlight the professionalism of the Unic Rotarex® team. Positive customer experiences confirm the advantages of a modern, reliable, and efficient steel frame construction system.
