The Zeman Group largely has its own resources in the areas of engineering, production and assembly. Nevertheless, it sometimes makes sense to provide services together with partners. For example, if a particular specialisation is required, the project requires extremely long transport routes due to its geographical location or the investment requires the involvement of local companies, partner companies are gladly used. For the provision of these external services, the Zeman Group relies on tested and certified partner companies, with whom it usually has a long-standing business relationship. For example, the Zeman Group has supplied companies in the steel construction industry with high-quality machines for decades. These same companies are now often our suppliers. If necessary, in-house supervisors are provided. The supervision of external production is carried out by our own trained teams.
