A fusion of tradition and innovation
Almost 100 years of experience in the development and production of closing solutions and building hardware matched by the use of modern technologies form the basis for high-quality products made by DENI®. Today 50 qualified employees apply their know-how on a production area of 4000 m² at the location in the so-called „Key Region of Velbert/Heiligenhaus“– a globally unique agglomeration of the lock and fitting industry. Continuous investments in the modern machinery stock, the aluminum foundry, the installations for surface treatment, ERP- and CAD-system and, last but not least, the qualification of the employees, guarantee a sustainably high level of performance.
The matching hardware for each component
DENI® stands for a wide range of closures and fittings. Especially the program for double-winged door systems is extensive. When it comes to locking inactive door leafs, DENI® offers the matching product for almost any mounting situation.
Play it safe with DENI®
The issue of safety technology is increasingly gaining significance. DENI® has realized this trend in good time, so the company is intensively involved in the creation and expansion of the DENISAFETY segment. The range of this segment includes retrofit security mechanisms for windows, French windows and doors. The underlying philosophy is to combine highest safety standards with aesthetic requirements met by a slim and unobtrusive design. Correspondingly, DENI® develops own innovative solutions.
