About bewa-plast
bewa-plast Beck GmbH Fenstertechnik is a medium-sized family company based in Mengerskirchen (Hesse) and has been manufacturing plastic windows, entrance doors, sliding doors, roller shutters and technically coordinated window accessories since 1952. Across approx. 33,000 m² at two sites, around 250 employees produce individual complete solutions for new construction and renovation in residential and commercial construction. Production includes profile cutting in the cutting centre, profile machining in the machining centre, corner welding using the Fineline welding process introduced in 2024, and post-processing in modern cleaning centres; roller shutters are manufactured fully automatically. Branded PVC profiles with lead-free calcium-zinc stabilisers are processed, with the profile core consisting predominantly of PVC recycled granulate as part of the Rewindo recycling initiative; supplemented by aluminium for roller shutters, entrance doors and cover shells, steel for glass rebate reinforcements and safety glass. The products carry the RAL quality mark, the KEINBRUCH quality seal according to DIN EN 1627 (RC2/RC3) and the SHI product passport for sustainable building. Customers are specialist window fabrication companies, property developers and commercial construction companies, who are offered full service including delivery with an own vehicle fleet and installation teams.
