Five Brands. One Vision.

BSW, CES, FSB, Norseal and Woelm (HELM Sliding hardware) are 5 companies steeped in tradition with a shared vision and a shared aim: to offer our customers every door-related product from a single source – made in Germany and perfectly coordinated both in the technology they use and the materials they are made from. Our synergies are your advantage. With our package products you are always safe and secure, and you benefit from fantastic prices and guarantees. The ties between our brands are clear to see. We know what commercial and public buildings need and we use our combined expertise to benefit our customers. This has naturally led to our shared specification service, which takes a load of the work off of your shoulders. Our total product range meets international standards. Certification under ISO 14001 is your guarantee of long-lasting, sustainable products. We believe so firmly in the quality we deliver that we offer a 10-year functional guarantee.
