QDS24 is a company specializing in the production of HS lift and slide doors made of PVC and aluminum profiles. They are used both in public buildings and in single-family housing, serving as a comfortable exit to the terrace or garden. This extremely visually effective and convenient solution is increasingly winning the hearts of investors and becoming a very popular solution. The design of lift and slide doors allow for unrestricted arrangement of space. They also provide access to a large amount of daylight and the impression of close contact with the natural surroundings of the building. The HST door technology allows you to create large-size structures.

We focused on a narrow specialization to ensure the highest quality of workmanship and reliability of operation. We provide our clients with what we know best. Our business model is outsourcing production, commissioned by other companies producing joinery. We also work with window dealers, developers, construction companies and architects.

 Promstahl is the exclusive trading partner of QDS24 in contacts with companies that assemble and distribute joinery.
