Window bars are a necessary measure of protection against intrusion into an apartment or house from the outside. The invention is not new, but many continue to install fixed structures that tightly block access to and from the house. Thus, in case of fire or other danger, it is impossible to leave the house from the inside through the window, and what protected you from robbers turns the house into a trap.
A small design improvement - the ability to move the bars apart or open them like shutters - may one day save the lives of the residents of the house. Locked sliding bars (see photo below) are in no way inferior to a monolithic structure, and when open, they almost completely free the window opening.
Design features
Like conventional grilles, sliding ones can be solved in completely different aesthetic terms. According to their appearance and degree of strength, they can be divided into:
- standard;
- artistic;
- banking.
Standard
In turn, standard sliding bars for windows come in seven types, each of which corresponds to a certain type of building. Such window protection is used, as a rule, in residential and office premises, as well as in shops, warehouses, etc. The standard design involves powerful vertical supports and a suspension mechanism for moving the leaves. Such a system is usually very durable, therefore, for industrial buildings it allows the use of strong and heavy metal doors.
Artistic
Artistic designs of sliding window bars are called, which are decorated with decorative prints on the bars. They are installed when there is no need for increased protection, but there is a desire to make the house more attractive. Artistic sliding bars are also used in cafes and restaurants to decorate the interior and provide protection.
For the manufacture of artistic structures, special equipment is needed, which allows you to create, depending on the design solution, the effect of hand forging or fantastic wicker patterns. With the help of acrylic paints, sliding lattices can be turned into a real work of art.
Banking
Sliding bank bars on windows got their name due to their increased strength. They are installed on the windows of rooms that need increased protection, such as, for example, a cashier's cabin. Open without a key or special tools suchgrating is not possible.
Designs of sliding bars on windows
Whatever the specific purpose of the gratings, they can be made in a variety of ways, while observing the general principle of operation.
Rods are round or faceted, of different thicknesses, they are fastened together by a moving part like a hinge. Lattices usually move on the principle of scissors. This design is the most durable and has proven itself in operation.
Mobility of the sashes is provided by a hidden roller mechanism or due to the upper suspension.
What are window bars made of?
The most common, time-tested material for window grilles is steel. But it can be processed and presented in a variety of ways: round and square or polyhedral section, thin strips of steel or a combination of rods of different shapes.
If you take the choice of material for gratings seriously, then it is best to focus on structural steel, as it is better than other types of welding.
When greater strength is needed and if there is a risk that the gratings will be cut through, alloy steel will do, but is rarely used. As a rule, at the individual request of the customer.
For household needs or institutions that do not store something incredibly valuable, structural steel is also suitable, it is also not easy to saw through, especially if you use thicker rods for a sliding lattice. Attackers will have to tinker for a long time, and the point is not in the material, but in a movable structure consisting of small parts interconnected. So if we talk specifically about sawing, a sliding grate for him is a much more difficult obstacle than a static one. In addition, from the rhythmic movement of the cutting object, whether it be a mechanical or electric tool, the entire lattice structure begins to shake, which greatly slows down the sawing process.
DIY sliding bars. What do you need?
First of all, the material: metal bars, stripes, arcs - whatever you want to see on your window.
It is necessary to measure the window, then make a detailed drawing of the future design. Naturally, the empty spaces in the lattice design should not be sufficient for even a thin child to crawl into them. Otherwise, why all the effort then?
Further, the manufacturing of sliding gratings is already carried out directly: bending the rods into the desired shape, welding parts if necessary. The lattice is framed by a frame equal in size to the window opening.
After welding the main structure, you can proceed to the decor, if it is planned. Of course, a simple lattice is enough to protect against robbers, but with wrought iron decorations, it will not evoke sad thoughts, but, on the contrary, will turn into a highlight that sets your windows apart from the rest.
Only people familiar with the operation of the welding machine and capable ofmake movable riveted joints of parts. Some craftsmen also use screw connections. In this case, the screw heads can act as a decorative element in the lattice pattern, but care must be taken to block the unwinding.
Sliding gratings: installation
You can mount the resulting structure either directly into the window opening or on the wall. The first option is considered more reliable due to special metal pins that are embedded in the wall. Installation of this design can be made in almost any room. The final cost of a sliding grill depends on the number of fasteners used in its installation.
