Our manufacturing journey began in 1987 — first as a Pimapen fabricator, then with HT Troplast, and later under the Kömmerling brand — and continued for almost four decades. Over that time we gained invaluable experience, built lasting relationships and delivered many successful projects. In 2026 we opened a new chapter — choosing to join forces with a company that shares our vision, values and long-term commitment to quality and innovation. Today, we are proud to be part of the GEALAN family.
“Here’s to fair winds, new horizons, and a successful journey together.”
