Metal is a fairly popular material used in the manufacture of fences. This is primarily due to its mechanical strength, accessibility and ease of installation. There are a large number of metal fences made of metal. We will consider their features and installation technology further..

Metal fences are increasingly being used as fencing or territory separation. Metal is an easy-to-process material that can be used to build fences of various shapes. In addition, the following advantages of metal fencing should be noted:
- the strength and reliability of the structure – a metal fence will serve you for many years, provided that the metal is properly treated with anti-corrosion compounds;
- metal is an affordable material, so its cost is much lower than the construction of a concrete fence;
- metal – resistant to combustion and fire, therefore the level of fire safety of such a structure is at a high level;
- metal fence – practical and does not get dirty, and if necessary, it is easy to clean;
- there are a large number of paints for metal, so you can paint such a fence in any color;
- unlike wood, metal is resistant to moisture, temperature changes, ultraviolet radiation;
- metal fences are easy and quick to install, unlike brick, stone or concrete fences, no special skills or tools are required to install the fence.
Metal fences differ in the type of material from which they are made. The simplest, easiest and most economical solution would be to use a chain-link mesh for the manufacture of fences. The height of the fence will turn out to be about 1.5 m, with its help it will be possible to divide the site into several zones and protect them from outside intrusion.
A welded sectional fence is distinguished, first of all, by a long service life, but the cost of such a fence is quite high. Such a fence has an attractive appearance and functions as the main fence for the site. For the manufacture of sections, special pipes are used that improve the quality of the fence operation. To decorate such a fence, forging and various decorative elements made of metal are used..
The most popular option is corrugated board fences. The cost of their construction is lower than that of sectional ones, and the quality and duration of operation are at a high level..
The corrugated board has the form of a steel profiled sheet covered with a zinc layer. Thanks to this, it is resistant to corrosion, ultraviolet light, and retains its color well. For coloring the corrugated board, a special polymer-based enamel is used..
A fence made of corrugated board has the following advantages:
- such a fence is easy to install and does not need an additional foundation;
- corrugated board is resistant to high and low temperatures;
- attractive appearance is another indisputable advantage of this material, there are many options for corrugated board that differ in shape, size and color;
- a solid metal fence will cost you more than a corrugated board fence;
- corrugated board provides protection of the site from dust and has good sound insulation characteristics.
Another option for metal fencing is metal picket fences. For the manufacture of such a fence, a picket fence and crossbars are used directly, painted with polymer paint. Thus, it is possible to choose a fence of the color you need..
Unlike a wooden picket fence, a metal fence will last several times longer. Since the metal is more resistant to moisture, temperature changes and other external irritants. However, the cost of such a fence is also higher than that of a wooden one. The steel picket fence looks very nice in combination with brick supports.
We suggest that you familiarize yourself with the features of installing steel poles for a metal picket fence. In this case, the pillars function as supports. They are made from both metal and other materials such as wood, concrete or brick..
Most often, steel supports are used in the form of pipes, with a diameter of about 60 cm. Please note that a steel picket fence is heavier than a wooden one, so the supports should easily withstand the load from the fence itself, wind and other mechanical damage.
Steel posts – a universal option for installing a picket fence, and for a fence made of mesh or corrugated board.
In the process of installing metal fences and pipes, you will need:
- shovel or drill;
- welding machine;
- cord and level, for marking.
The site is preliminarily cleared of vegetation and debris. Further, the markup is made on it. With the help of a cord, the place of installation of the support pillars is determined. With proper calculation, it will be possible to prevent deflection or distortion of the protective structure.
Next, you should calculate the number of pillars installed on the site. The method of installing one or many pillars depends primarily on the type of fence, its weight, as well as on the individual characteristics of the site.
The simplest and most popular method is to fill the support pillars with concrete. This method is suitable for soil with optimal moisture content. Initially, you should dig a hole under the post, install the post and fill the remaining space with concrete mortar.
In order to facilitate the drilling process at the site, water is used, which softens the soil. If the height of the post is no more than 150 cm, then the depth of the hole will be no more than half a meter. When installing higher pillars, you will need to equip a hole with a size of 70-80 cm.
If the soil on the site is not very heaving, then it is enough to drill a hole with a drill and install a support. However, the hole must be drilled in a strictly vertical direction..
However, if the soil on the site has a high moisture content, then a different method of mounting the support posts will need to be used. In this case, the pole must be installed below the level of soil freezing. In addition, before starting the installation of the post, at the bottom of the pit, a crushed stone pillow should be arranged, about 18-20 cm thick..
Thus, it is possible to equip the so-called drainage system and it is possible to soften frost heaving on the soil. A concrete solution is used to fill the last 15 cm of the hole..
The second method of installing steel supports involves driving them into the ground. This method is often used on soils with a low stone content. For driving, a special structure is used, for the manufacture of which a steel pipe and a weight located at its end are used. The blow must be carried out strictly on the object axis, so as to end up with an even support..
After installing the supports, the process of installing a metal picket fence follows. To fix it, a profiled pipe with a size of 4×2 cm is used.It is possible to use pipes with a large cross section, however, this option is the most optimal.
Metal supports and profiles are painted in the same color as the picket fence. The steel picket fence is in the form of elements of a certain length, for the manufacture of which galvanized steel is used. There are a large number of picket colors, both bright and calmer and unsaturated. Most often, a galvanized layer is applied to the surface of the picket, 0.5 cm thick.
The main requirement for obtaining a high-quality fence is the correct marking and installation of supports. Further actions are of the same type and involve fixing the picket fence on the profile.
The aesthetic appearance of the fence determines the distance between the pickets. Therefore, before installing them, you should determine the length of the fence between the supports and divide it by the width of the picket fence. Observance of large intervals is impractical, as due to the excessive load, there is a risk of the fence sagging.
In order to prevent rapid wear of the picket fence, it should be located at a certain distance from the soil. The optimal value is 10 cm. It is possible to build a blind fence, in which the picket fence is located at a minimum distance from each other. The air version of the fence assumes the location of the picket fence at a certain distance from each other.
To fix the elements of the fence, you will need fasteners in the form of self-tapping screws or special bolts with washers. The washers will help prevent damage to the galvanized coating and corrosion of the picket fence. It is possible to use special mounts, the same as the picket fence itself.
Galvanized fasteners are the best option for installing a picket fence, since its service life is the same as that of the fence itself. Make sure to keep the same spacing between the pickets, otherwise, the fence will look asymmetrical.
Before starting work, you should determine the total perimeter of the fence, based on this indicator, it will be possible to calculate the amount of material for work. In addition, pillars with a length of 150 to 250 cm will be required. The interval for their installation is about 3-4 meters. You will also need metal lags or wire, with their help it will be possible to fix the mesh.
Please note that before installing the mesh, the supports should be painted with a special paint with anti-corrosion effects. Next, the supports are installed under the mesh. Initially, the pillars are mounted, then the logs, and then the mesh.
The posts should be installed at the corners first. Pay attention to the evenness of the mounting of the supports. They must be strictly upright. The depth of the pit for installing the supports is about 50 cm.Crushed stone and, if possible, concrete mortar are used to backfill the supports.
Use a water level to check the installation height of all supports. Next, the lags are mounted. To fix them on the surface of the supports, bolts and nuts are used. After that, the mesh is installed and fixed with an aluminum wire. The lower fixation of the mesh is carried out using special brackets. Possible use of plastic clamps.
Installing a fence from corrugated board includes certain stages, such as:
- preparation of the base and execution of the marking;
- installation of support pillars and installation of lags;
- installation of corrugated board.
The first stage is very important, since the evenness of the resulting fence depends on the quality of its implementation. The maximum spacing between posts is 300 cm.In order to determine the required number of supports, divide the fence perimeter by 3 m.
Pipes of square or round cross-section are used as supports. The minimum value for square pipes is 5×5 cm, and for round pipes – 7 cm.To avoid moisture getting into the inside of the pillars, the lower and upper holes should be welded.
The depth of the pit for the posts is about 100 cm, and the width is about 15 cm. For these purposes, it is preferable to use a hand drill. The depth of the holes for the installation of supports depends on the height of the fence.
The pillars should be well fixed on the ground, since, in addition to the weight of the fence itself, they are susceptible to mechanical influences and the force of the wind. Medium-fraction gravel, about 20 cm thick, should be poured onto the bottom.Further, the column is mounted and poured with concrete..
Use a plumb line to install the poles. For additional fixing of the supports, weld steel rods to them and also pour concrete. After the concrete has hardened, lags are mounted between the supports. Most often, steel pipes are used as lags. If the height of the fence is more than 1.6 m, then two logs are enough. Otherwise, three lags should be installed. The lags are fixed on the supports using a welding machine. In order to protect them from moisture, they are coated with an anti-corrosion solution..
Please note that if the installation of the fence is carried out in the spring, when the soil is oversaturated with moisture, then it is better to first build a shallow strip foundation. With its help, the fence will become more durable and stable. If this is not done, then the fence may sag. The final stage is the installation of corrugated board on the logs. The sheets are joined together in a small overlap. In order not to get hurt, wear gloves, as the corrugated board is sharp enough.
Use only metal scissors or a hacksaw to cut the sheets. The use of a grinder will lead to the destruction of the galvanized coating and to the appearance of metal corrosion. In order to fix the corrugated board on the logs, special staples are used, the same color as the material itself.
A fence made of corrugated board is a practical, inexpensive and easy-to-install solution for making a fence. In addition, subject to all installation technologies, such a fence will serve you for more than ten years..
