When design and function flow together.


Our extensive product portfolio enables us to always meet the most diverse requirements on cruisers with our folding doors. Custom-made and high-quality, our folding doors are being manufactured in different versions by us. A large selection of locks and fittings also ensure that all doors can be optically integrated into the design of the cruiser.

First class fire protection.


Fire curtains require little space and can be perfectly integrated architecturally. The certified curtains protect different areas from spreading fire by preventing the passage of flames and burnt gas. The fire curtains are tested under a temperature of 945 ° for 60 minutes. Fire protection on sea is particularly demanding. All the better, if you can combine security and first-class design.
