Schwarzmann – Your Supplier of Prefabricated and Tent Steel Halls
Since 1993, the Schwarzmann team has been designing, manufacturing, and constructing prefabricated steel-structured business buildings.
We specialize in custom-designed business structures tailored to the specific needs of companies, supporting their growth and development. Over the past 30 years, we have completed over 700 Schwarzmann buildings across 25 countries, covering infrastructure, production, and commercial spaces.

Through well-defined processes and extensive expertise in designing, engineering, manufacturing, and assembling steel-structured buildings, we effectively meet the spatial needs of growing companies.
Focusing on innovation and finding new solutions, we aim to contribute to the personal development of our employees, maintain harmony with the local environment, and drive progress in our industry and the Slovenian economy. Our goal is to combine our experience and knowledge to solve the specific spatial challenges of businesses and support the development of our partners.
As a socially responsible company, we are actively involved in the local community. As the largest employer in Polhov Gradec (Slovenia), we recognize our responsibility towards our employees and the area. In recent years, we revitalized the degraded site of the former Hoja Mobiles company in the Polhov Gradec industrial zone. Through the restoration and modernization of production halls and landscaping, this area now serves the community, offering suitable working conditions for employees.
