Hardware systems for doors have witnessed a tremendous progress in parallel with the systems for windows, although developments in that field was not as obvious as in other cases. Moreover, most of suppliers promote both product categories, but the emphasis in terms of development seem to be placed in a different direction. Nothing less true, and the evidence consists of many solutions recently launched, aimed at improving the security elements and the design features. Meanwhile, researchers are moving towards identifying ways to enhance the properties' comfort in use, functionality, accessibility etc. The results are outstanding and demonstrate the ability to adapt to the new demands of consumers, in the current context of sustainable development, focusing all energies to energy efficiency, environmental behavior and socio-cultural compatibility. Hinges, simple products at first glance, are solutions which have been well developed in recent years, as increase in bearing capacity, accelerate the degree of automation, improved access facilities or increasing the safety degree. Must not be forget the aspects of design, door hinges being subject to continuous efforts to adapt to the architects requests. On the specific market were launched products with concealed installation, which allow the transfer of electrical cables, models which can equip doors with weights of 300 kg or more, benefiting from facilities of 3D adjustments, complex assemblies intended for installation in wood, PVC and aluminum doors, solutions allowing openings of up to 180° etc. Also, major producers active on the international market focuses on promoting assortments with a high degree of adaptability, which can be used in a diverse range of applications (interior, exterior, functional etc., regardless of the material of which they are executed). The security features have recorded, a permanent progress, the available variants being characterized by high levels of burglary resistance. Metal parts of the systems are protected with anti corrosion finishes and the products which require superior driving tasks are made of stainless steel high performance materials.
