our history

The company was founded in 2013 and gradually grew to achieve the status of a reputable brand. After an introductory period entering the market and several successful international projects, the company became a professional and recognized provider of services in the welding and assembly of various types of steel structures.

Currently, we employ experienced assemblers, welders, fitters, machine and equipment operators, foremen, health and safety inspectors, as well as quality controllers, whose skills and work ethic are the cornerstone of our operations.

New location

At the end of 2022, we relocated our company headquarters from Staszów to the area of the Staszów Economic Zone in Grzybów. Thanks to the newly built workshop, we were able to start independent production of steel structures. Orders fulfilled by us in Grzybów are produced for both Polish and foreign customers.

The new location allows us to grow even more dynamically, expanding the range of services we offer. Already, their high quality is something we take pride in. In the long run, we aim to gradually increase our production capabilities, never forgetting the importance of both professional execution and individual approach to each project. Our goal is to deliver to the market steel structures designed and created by us from scratch.
