The problem of panel warping and door hinges Using a correctly sized hinge system has the advantage to avoid many unnecessary processes, which tend to weaken the door and frame structure and that are then visually unpleasing. Hinge systems which, with the necessary technical measures and dimensions, are able to offer a complete solution to most application requirements. That said, it’s easy to see why product families have developed over the years, with incremental capacity in order to support increasingly large and heavy doors properly. both hold up the vertical thrust, i.e.the bottom hinge holds up in thrust (F2).the top hinge holds up in traction (F1).Hinges that carry the weight of a door and which are affected by the greatest efforts are always two: Dispel so once and for all the myth that most hinges are installed on a door, more the load capacity increases in proportion. We tend to think that if two hinges carry 40 kg, 80 Kg doors can be handled by installing 4. How many hinges carry the load of the door? It is not absolutely true that mounting 3 hinges you a 50% increase in load capacity nor that installing 4 hinges capacity even doubles.an increase in the width of the door has a negative effect on the load capacity of the hinges.an increase in the height of the door (and therefore the distance between hinges) has a neutral or positive effect on the load capacity of the hinges.It is also good to know that, leaving constant the weight of the door: Therefore, unless indicated in the technical documentation of the hinge, you should check that the declared capacity is actually related to the above. Table that allows to identify in which situations the 200 Kg load capacity stated by the manufacturer is guaranteedįrom these assumptions, then it starts every consideration related to load capacity when you have to define the appropriate handling of a specifics door hinge system. 200,000 opening cycles, for use on doors.

use of two hinges, one load-bearing (in the case of concealed hinges both hinges are load-bearing).mass (or weight) of the test port based on the category that you want to achieve.a standard door 2000 mm (h) x 1000 mm (w) and a distance of 1540 mm between hinges.When it comes to load capacity of hinges instead, you have to make reference to the inter-relation of multiple elements and in particular the following:Īll CE marked hinges, that is, all those hinges which are produced, tested and certified according to EN 1935 regulations provide as follows: The weight of a door is the value, expressed in Kg, which is obtained by positioning the door on a weighing scale.
