Window manufacturers and fitters

We are proud of every lift and slide door that leaves our company.

The fact that our slogan is "Die Hebeschiebetür" (The lift and slide door) is no coincidence. SCHMIDT GmbH has been focussing on the production of lift and slide doors since 1976 - since 1990 on the basis of the in-house development of the profile system. And that is also one of the main reasons why SCHMIDT GmbH is your partner. Just as with the product, we also focus on one target group for the customer - the window manufacturers. When it comes to challenges regarding lift and slide doors, we are at your side from offering advice to service. Why? Because we can. No other custom producer is as deeply involved in the technical details as the SCHMIDT team. This means that you not only have a sophisticated technical system in the foreground, but also comprehensive expertise in the background for your everyday projects. And if there's ever a problem, our service team is available for you on site.

Ease of installation is decisive

With their QuinLine® lift and slide door, SCHMIDT offers you a particularly easy-to-install product. The profile system is not only lighter than other systems, which is important for easy transportation on the construction site, but is also very forgiving.

Since the installation of lift and slide doors is different from that of windows, SCHMIDT offers comprehensive information material as well as training for fitters.

Because if you know what to look out for, handling on the construction site becomes much easier. For window manufacturers, this means a significant minimisation of time and costs.
