We manufacture door panels and door leaves mainly with aluminium and GRP surfaces on behalf of metalworkers and specialised door manufacturers.

Due to the sandwich structure, the door panels and door leaves are light and at the same time very stable with good thermal insulation. The self-manufactured core material consists of a PU cell structure, similar to the structure of bones. Unlike wood, MDF or rock wool, it is insensitive to moisture and does not swell. It is also more stable than EPS or XPS. Our special manufacturing process results in perfect surfaces. On customer request, we integrate inserts into the core as reinforcement or fastening structure for hinges and locks.
