Doors in steel/chromium steel: Fire protection doors for all-encompassing safety aspects
Highly frequented buildings in the public and commercial sectors such as, for example, schools, sports stadiums, hotels or office buildings, must legally be equipped with fire protection doors of different fire resistance classes. We at Bühlmann are firmly convinced that fire protection doors shouldn’t exclusively have a practical design, but rather they also have to meet aesthetic demands.

Technical clarifications for the desired fire protection doors can take a lot of time. As a longstanding specialist for F30, F60, F90, F120 fire protection building components, we would be happy to relieve you of all the necessary detailed tasks. It doesn’t matter whether this is for EI30 single-leaf fire protection doors or a multifunctional portal door with generously dimensioned EI90 fire protection glass.
