The Project Manager has the authorization and responsibility for communication with the customer, for the project's progress according to its schedule, as well as for anything else that may be required for the project's successful completion.

3D Design

In-house design and planning department that offers the best possible solutions. The production of steel elements is driven by advanced software systems that enable modelling through three-dimensional design, ensuring not only the seamless flow of information during the construction and erection phases but also the construction's flawless structure.

Crane erection

If required depending on the situation, we work with external partners with long experience and proven reliability, who are committed to the smooth completion of the erection and always with safety among their top priorities.


The production equipment consists of ultra-modern machinery for cutting, punching, mechanical treatment, welding and forming. The techniques and procedures implemented during the assembly stage ensure that tolerances are much lower than those allowed. Superior quality is enhanced by the fact that the parts of the construction are sand-blasted in order to ensure that the surface is clean and free before welding.


With our significant experience over the years and our network of partners, our is capable to offer our customers the best possible solutions regarding transportation of their constructions.

The decision should be taken at the beginning of the design process and take into account the climatic conditions of the building site as well as the architectural style of the building itself.
