Four generations of the Winkler family have shaped one mission: developing fasteners that hold — reliably, decade after decade. From a Berlin metalwork shop in 1904 to an internationally leading supplier of fasteners and fastening systems for surface temperature control. We deliver to more than 30 countries — and produce exclusively in Germany & Switzerland.

We develop and distribute innovative fastening systems for surface temperature control of buildings, halls, stadiums, driveways and airport runways. A wide selection — top quality produced in Germany and Switzerland.
Strong values shape our actions — towards customers, partners and within our team. They define us as a family business, employer and business partner.
Together for our customers — every day, no compromises.
We treat others the way we want to be treated.
We do what we say. Trust is the foundation.
We talk with each other, not about each other.
