MANUFACTURING PROCESS CERTIFICATIONS
Golden Door protects the environment by assessing its raw materials and using only environmentally certified materials.
The wood used is certified as not containing formaldehyde, a substance that is carcinogenic for humans. Furthermore, our wood dyes are water-soluble, to ensure they do not contain solvents harmful to user health.
Another important certification is ISO 9001, which ensures the consistency of the manufacturing process and the company's commitment to the continuous improvement of its organisation, for its own and consumers' benefit.
Study at the National Technical University
The study conducted at the National Technical University on GOLDEN DOOR doors specifies the high quality of the product as regards the door's durability and rigidity. The results of this study were presented with great success at a European conference.
Patented door frame
The GOLDEN DOOR frame is a closed type metal frame, patented with patent number 1004810. Unlike open type frames, the GOLDEN DOOR frame is superior, as the perimeter pins (fixed & mobile) of the door are impossible to locate and breach, thanks to the door frame's closed shape. Furthermore it offers antiseismic protection, as it can withstand heavy loads without the slightest deformation in case of earthquakes. Its automated construction, using a cutting-edge CNC roller, offers consistent quality of high standards. All parts of the frame are galvanised to avoid oxidation and are coated with electrostatic paint for maximum tightness. The ledges are fixed perfectly onto the frame, in order to avoid the use of screws. A study carried out at the National Technical University confirms the durability of the security door. Using a 3D parametric model of the door and frame, loads were applied at various points and the deformations caused on the door were studied. The conclusions from the above analysis demonstrate that there is no risk of breakage at any point of the structure.
Patented hidden hinge
The GOLDEN DOOR hidden hinge is patented with patent number 1007375. It is exclusively designed for armoured doors, aiming at an enhanced aesthetic effect. On its inner side, the door is flush with the wall, since this is a recessed hinge. Its manufacturing features allow it to be adjusted in both height and width. At the same time, the internal bearings of the hidden hinge allow the door to slide easily and open smoothly, while the strength of each hinge is 1000kg, thus making it able to withstand heavy loads.
