the basic performance features can be combined with a wide range of high-level performance features in a single door, whether it is fitted indoors or out!<\/li>\n<li>Another reason for this endurance is the use of screw-on hinges. This makes it possible to adjust the door in three dimensions after it has been fitted, guaranteeing that it is perfectly adapted to its location; ensuring maximum ease of use; and avoiding the malfunctions ordinarily caused by the heavy-duty use of the door. As the exterior plates are also screwed on, there is no need to change the entire door set: only the damaged part is replaced.<\/li>\n<li>Thanks to the unique Metal+ Inside concept, Heinen doors are constructed on the same basis and always have the same attractive look, regardless of their performance features. All Heinen doors are made to measure, up to 6m!<\/li>\n<li>The great advantage of Heinen doors is that the performance features can be combined on a bespoke
