Alcon has strict quality criteria. From designing, controlling the production process (FPC), cutting and assembly to packaging and shipment of its products. As far as the CE marking is concerned, all the products of the company now have a unique id number, which helps in the traceability of its products.

Product design is made by experienced and skilled staff with modern programs (autocad). These executives are also responsible for designing new products (R & D), which, after control, integrate them into the production process.

The FPC (Factory Production Control) applied to our company requires us to make continuous inspections throughout the production process from the receipt of the Rolling Shutters, cutting, assembly, glazing installation, packaging to the placement of frames in the building. Specially trained crews place our cases on the basis of instructions and specifications of international standards, with all the necessary small parts necessary for the proper fitting of the frame in the building.
