Modern gates, like any metal products today, have little in common with the metal gates that decades ago separated the street and the courtyard (garage) of private owners. Decorated with forged ornamentation, carefully designed and executed iron gates perform a greater number of functions - they serve as both a means of security and a decorative element of the exterior of a private estate.

According to their purpose, iron gates are distinguished into industrial and household, garage and entrance gates. According to the conditions of GOST 31174-2003, metal gates are divided, depending on the action, into sliding (sliding) and swing, folding (sectional) and lifting. What matters is the gate opening / closing mechanism - mechanics or electric drive.

Steel gates - features of each type

A greater resource is laid in the design of industrial gates compared to domestic gates, because the first type of gates will be repeatedly opened / closed during each day. Steel gates for domestic use are used less often - maximum two to three times a day, so they have a shorter resource compared to industrial ones.

Sliding (sliding) gates allow vehicles to come close to them, do not require free space in front of them. Mounted on a profiled steel beam, they move left / right with sufficient ease on a mechanical or electrical drive. The space under the gate is free, the design of the sliding gate rests on roller supports outside the opening, so the owners do not need to constantly clean up seasonal deposits in the form of snow and foliage. Particularly attractive about sliding gates is that their design allows the passage of vehicles of any height, because there are no structural elements above the sliding door leaf. Various finishing materials are used for this metal product - hot-rolled steel sheet, sandwich panel and corrugated board, followed by painting according to the general exterior of the object.Installation of sliding gates is carried out in the warm season; rigid console blocks and a high-quality wall foundation are required. The maximum width of sliding (sliding) gates is 12 m, the height is 4 m. In this case, the door leaf must have a length that is 1/3 greater than the width of the opening.

Metal swing gates are one of the oldest gate structures. Low cost, ease of use and high reliability make this type of metal products invariably popular. The swing gate design includes two leaves, symmetrical to each other, with hinge fastening on the gate supports. In some cases, the gate support is made in the form of a rigid contour consisting of vertical posts and vertical jumpers that close the contour. Metal swing gates open both outward and inward, depending on the free space. Cladding can be made of steel sheet and siding, corrugated board and applique, stainless steel strip, clapboard and sandwich panels. For example, swinging wrought-iron gates in an arched style look great. The sash frames are made of a profile pipe,sizes from 45x25 mm to 80x40 mm, the maximum length of each leaf is 7.5 m. The swing gate drive can be either mechanical or electric.

Folding (sectional) metal gates consist of several rectangular sections interconnected. When opening such gates, they fold up like an accordion, taking up a minimum of space and completely freeing the opening. The frame of the sections and the guides installed on the ceiling or wall are made of steel profiles. The inner space of each section is filled with hot-smoked steel sheet or sandwich panels, the sections are interconnected with steel hinges. The folding gate structure moves on steel trolleys along guides. Special locks are installed on the sections, in the upper and lower parts - synthetic brushes, which reduce the blowing of the wind. Possible dimensions of this metal product: the height of the sections is from 2 to 6 m, the total width of the door leaf is from 2.2 to 18 m.In the open state, folding gates will take from 0.25 to 0.9 m of space outside the opening,depending on the number of sections. Installation of supporting rails will require at least 0.3 m of the distance between the opening and the ceiling. Safety glass windows can be cut into the folding gate leaves. Gate drive - both mechanical and automatic.

Lifting gates (up-and-over or rolling), as a rule, are used to close garage openings, they retain heat well. Up-and-over doors consist of a gate leaf, a frame, a counterweight system and guides. A subtype of overhead doors are overhead sectional (the door leaf consists of two or three sections). The role of counterweights is played by springs that compensate for the sash weight. The gate opens from the bottom up: the sash rises, its upper edge goes along the guides to the ceiling and the entire sash is parallel to the ceiling plane. Such metal garage doors are completely made of metal - a steel profiled tube for guides and a sash frame, the sash space is filled with hot-smoked sheet steel. The cladding is made of profiled steel sheet,between the cladding and the base, a mineral wool or foam insulation is laid. Cladding can also be performed with a sandwich panel.

Rolling shutters operate on the principle of roller shutters (roller shutters), they consist of a box, guides and a shaft on which the door leaf is wound from lamellas. The door leaf of such a gate is built mainly of aluminum lamellas or steel profiles with internal insulation. When opening, the door leaf goes upwards along the guides, tightly wrapped around the shaft.

The maximum width of both types of overhead gates is 6 m, the height is 3 m. To install the gates, at least 0.2 m of free space is required between the leaf and the ceiling. Gate wing control - mechanical or automatic.

Application, average cost of each type of metal gate

Sliding (sliding) gates provide the greatest passage width, therefore they are used to enter large areas - summer cottages and cottage plots, industrial sites, etc. Prices for metal gates of this type range from 40 to 70 thousand rubles. (depending on the width of the web), installation work - from 12 to 15 thousand rubles. Installation of automation will cost 17-20 thousand rubles.

Swing gates are traditional and simple in shape and are therefore widespread. They are used as gates in private property and industrial facilities, construction sites and agriculture. The cost of swing gates is from 30 to 45 thousand rubles. (from the width of the canvas), installation work - 7-9 thousand rubles. The cost of automation is on average 16 - 20 thousand rubles.

Folding gates are used where a quick opening of a significant size is required - warehouse and aircraft hangars, rapid response stations. Prices for folding metal gates (sectional) will be from 40 to 175 thousand rubles, installation - 15 - 20 thousand rubles. The cost of automation is from 8 to 15 thousand rubles.

Metal garage doors - lifting and roll-ups are installed mainly on premises for storing vehicles. In addition to garages, gates of this type are used at car service and washing stations; installation on aircraft hangars is possible. The prices for lifting and rolling gates will be from 26 thousand rubles. up to 180 thousand rubles. (depending on the width), installation work 8 - 20 thousand rubles. Equipment for automation - 6 - 20 thousand rubles. average.
