Hinges for doors: types and features

Ease of operation of doors to a large extentdepends on the quality and the right fittings. First of all, you need to choose the right hinge for the door. They are brass, steel and brass. The most popular and affordable are brass, but because of the softness of the material, they can be used with a door leaf weight of not more than 35 kilograms. For doors weighing no more than 60 kilograms, use brass hinges. They are made from zinc or steel alloys and are top-coated with brass to give greater appeal, improve slip and protect against corrosion.

The most durable and reliable hinges are made of steel. Such fittings are installed on the entrance doors, they are distinguished by a long service life and high reliability.

Often during the use of hinges for doorsbegin to squeak. In order to get rid of it, they are lubricated with special oils, but after a while the creaking appears again. Some manufacturers use bearings to reduce the friction of the hinge parts. Such designs do not creak ever, but cost much more.

We are used to having two hinges on the door,but even for a canvas weighing 40 kilograms, 3 pieces are needed, two of which are set at the top with a distance between them of 20 centimeters. For heavy and massive door leaves (the height of which is more than 210 cm), 4 loops are required.

Design features

By the design of the hinge for doors there are screw-overhead and mortise. The most widely used overhead loops. They consist of two parts (wings), one of which is attached to the door leaf, the other to the box. By the way of opening they are right, left or universal. In order not to make a mistake with the choice, draw a plan of the house, on which indicate in which direction the doors open. Focusing on it, sellers will pick up the necessary accessories for you.

For protection against hacking use mortise orhidden hinges for doors. The peculiarity of their design is that the doors with the box are connected by a movable hinge, the body of which is fixed in a specially made recess in the door leaf and box. In the closed state they are almost invisible and present a certain complexity for breaking.

Screw loops have their name fromFeatures of the installation: they are screwed into the door leaf and the box, and do not crash (like other types). Their disadvantage is that if the quality of the door dense is insufficient, breaking or cracking of the wood in the fastening places is possible. Eliminate such damage is very difficult, most often requires a complete replacement of the door leaf. Despite its attractive appearance, screw-on hinges are not widely used.

Hinges for glass doors

Special requirements are imposed on the fittings forglass doors. Glass is a very whimsical and specific material, so the hinges used in such doors differ constructively: they are attached to the door glass sheet by means of special brackets with rubber inserts. Such hinges for doors are made of strong materials, because the glass is quite heavy. Some models have a built-in door closer, which protects the doors from sudden slamming and damage.
