The need to protect housing from intrusion by unauthorized persons is especially relevant for residents of the lower and upper floors of high-rise buildings and the private sector. Window penetration is the most popular way to rob an apartment whose windows are easily accessible.

That is why people try with all their strength and methods at home. The most affordable way to protect window openings is to install metal bars.

Types of window bars

The first principle of dividing lattices into separate types is method of making them... The lattice can be:

• welded;
• forged.

Impact resistant carbon steel is used for both varieties. The following types of steel profiles are used for gratings:

• round bar;
• square;
• strip - flat steel strip of rectangular section;
• profile with a combined section.

In this case, the surface of the profile can be either smooth or corrugated. This is determined by the wishes of the customer and the sketch of the future product.

At the place of attachment lattices are divided into:

By opening type lattices are of three types:

• deaf - the rigid frame of the lattice is firmly fixed in window opening... Firefighters do not approve of such grilles, since in a dangerous situation (when there is no way to leave the house through the door) people become prisoners of the apartment and often die.
• swing doors - most often consist of one or two opening doors installed in a rigid steel frame. The doors have hinges and are closed by hinged or steel. Such grilles are less reliable in protection from criminals, but they are safer from the point of view of the fire inspection.
• sliding - the doors of such grilles open by shifting to the side. Not very popular type, but sometimes used.

By appointment lattices are divided into:

• security - made of a thick rod (at least 16 mm in diameter) with a cell of no more than 15 cm. They guarantee a high level of protection of the house from penetration.
• decorative and security - from a rod with a diameter of 12 to 14 mm. Less durable than the previous ones, but have a more complex pattern and more attractive appearance.
• decorative - made of a thin bar (10 mm) or steel strip 4 mm thick. They have large cells and therefore provide a low level of protection. Mainly buildings serve.

Welded gratings

They are made from steel billets by welding. Do not think that these are simple ugly lattices. Elements are cut and deformed according to the sketch. Then they are fastened into a single whole by means of. Such lattices can be not only flat, but also three-dimensional.

In manufacturing, the bar and the square are hot worked, and the steel strips are cold bent.

The resulting products are durable and reliable, they are even beautiful, but you cannot call them elegant.

Currently steel grates rarely, more often they are still covered with special anti-corrosion coatings during manufacture, which increase the durability of the metal when exposed to atmospheric factors.

These are expensive items, especially if they are custom made.

Forging allows you to produce very beautiful lattices, the installation of which can complement and decorate the exterior of not only windows, but the entire building. Intricate designs of these lattices are composed of flowing lines, delicate flowers and leaves, arches, arcs and other intricate elements.

Previously, these products were produced by cold or hot forging exclusively by hand, but now they often use special machines.

Forged gratings are far superior in strength to welded gratings and are perfectly combined with various materials walls: wood, stone.

Often, to make the gratings more attractive, patinated metal is used - they "age" it.

The only big drawback is the high cost, which is beyond the means of most people.

A decent way out here is the use of combined grids, which are made by welding pre-prepared steel and forged elements. These products combine strength and. At the same time, the price is quite affordable.

Currently, roller shutters are often offered to protect windows. But they can only be in two positions "closed" and "open".

Moreover, in the closed position, the shutters completely block the luminous flux, and in the open position they do not interfere with intruders. For this reason, many people still prefer to install grilles:

• do not block the light;
• create constant reliable protection;
• durable;
• durable;
• easy to operate and maintain;
• easy to mount;
• resistant to weather conditions.

Installation methods for window grilles

There are three main ways to install window bars:

• using anchor bolts;
• welding to metal mortgages;
• fastening through the wall with threaded rods.

Fastening with anchor bolts allows you to install the grille on any wall - or wood. This is a universal method that allows you to install the grille both in the opening and overlay on the facade. The lattice has lugs through which anchor bolts are inserted into specially prepared holes in the slope or wall. After installation, the bolt heads are bored so that intruders cannot unscrew them and remove the grill.

Fastening to welding mortgagesconsidered the most reliable way. First, the embedded pins are driven into the wall to a depth of at least 12 cm, which protrude outward by 4 - 5 cm. The grate frame is welded to them.

Wall mountuse for. Through holes are drilled in the wall, through which bolts are passed, attracting the grating to the opening. On the reverse side, the bolts are tightened. This method does not decorate the interior of the house and requires decorating the bolt heads.

Thus, if it is necessary to protect their home, each person can choose the most suitable type of lattice, corresponding to both his aesthetic needs and budgetary possibilities.

Experts warn customers against self-measuring gratings when ordering them. It is better to call a specialist who will professionally assess the possibility of installing one type of grille or another and will make the necessary measurements, taking into account all allowances and mounting features.

For many people, grates on windows are a necessity, without which they would gladly do. Indeed: who would want to voluntarily enclose himself in a cage? But perhaps you will change your mind after this article. We invite you to discover how comfortable window grates can be and show you 30 photos of stunning art forging products that combine safety and visual appeal.

Why put bars on the windows of a private house and the first floor

The first reason that comes to mind is safety. When the apartment is on the ground floor or you live in a private house, window bars help keep your family and property safe from burglars. Note that they can be installed both from the side of the facade and inside the interior. In both cases, they can have hinged or sliding sashes, which leave the opportunity to admire a clean, unobstructed view from the window. Internal grilles windows are also placed on the upper floors when there are small children in the apartment - to prevent situations where the child can open the window himself.

Conventional welded gratings installed when facade decor does not play a significant role or there is a budget constraint. Even so, you can choose an original and presentable design. Distinguish between blind and removable welded grilles. Deaf people cannot be removed or opened, which is a huge disadvantage in the event of a fire. Removable ones are often used in summer cottages, so that during rest they do not see the sky in a box, and upon returning home, do not worry about their property.

Sliding window grilles are attractive because they can be compactly folded and hidden along the wall. The complex prefabricated structure somewhat reduces their protective properties, so they are often installed on the inside of the windows.

Front hinged grilles for windows have a locking and swinging device or a quick release mechanism that is accessible only from the inside. The advantage of their design is to provide a fire exit and ease of cleaning window panes while maintaining a high level of protection.
