When installing the fence, you can not do without pillars, which serve as a support for the structure and reliably protect the fences. It is on them that the material for the fence is attached, whether it is corrugated board, brick , wooden boards or slate. But how to choose poles for fence, if the assortment presents several dozens of types of supporting structures? About this below.
Classification of fence poles by type of section
These products have several classifications, but the most common are in the cross section and the material of manufacture. Depending on the type of section, all the columns can be classified into three types:
- Round pillars for fence . They are used when it is necessary to minimize the amount of land work, as they can be immersed in the ground by screwing or driving. In addition, lags are easily attached to them. The connection is through, easy to blow, it is easy to protect from corrosion with paint. The welded seam has a high tensile strength (about 1.2 tons per lag), which is several times greater than the load caused by the gust of wind.
- Square pillars for fence . They have a large flexural strength, but for this purpose the installation must be strictly parallel to the fence. But there is one drawback - the location of the lag to the pipe becomes a source of corrosion, which can not be stopped. This is due to the fact that a closed non-blowing plane is formed in the area where the pipes overlap, in which water can accumulate. And this is the condition in which iron corrodes very quickly. The weld seam only aggravates the situation. For 3-4 years the welded spike is completely destroyed and the fence has to be repaired or replaced. In addition to the described disadvantage, it should also be noted the high cost of products (square tube weighs more than a similar round and its price is approximately 30% higher) and the laboriousness of the installation (it is necessary that one face of the rectangle is in a common plane with a fence).
- Screw posts for fence . A convenient view of the piles, which has a tip at the end with a blade. They can be installed in any relief, without expending energy for excavation. Depending on the fence, you can choose the diameter of the pile structure. So, for a grid the pile in diameter of 55 mm will approach, for a metal profile - in diameter of 76 mm.

The type of section is important when calculating the cost of fence and the speed of installation.
The lineup
The most popular are the metal pillars for fence. They are very durable, perfectly combined with any kind of fencing and they can be reused. Piles made of metal are most often used when installing a fence of profiled sheet, metal rods or flat slate. Before installation, the posts must be painted to prevent metal corrosion in the future.

If you need a budget option, you can use wooden poles for fence. They can also have a square or circular cross-section. Before installation, the poles must be processed, the tree is very susceptible to the influence of moisture and wind. The part that will be buried in the soil must be treated with bituminous impregnation, which will make wood resistant to water and acids. The top part of the pile can be painted with colored varnish. Before processing, do not forget to dry and polish the piles.

Decorative poles for a fence
Some owners refer to the fence as a capital structure, which will serve as the protection and decoration of the house for many years. And to make it an integral part of the facade of the house, such finishing materials as brick, wild stone and special fence blocks are used. To erect a brick or stone pillar for a fence, it is necessary to pre-fill the foundation and then arrange the masonry according to a pre-selected scheme. The work is quite painstaking, but the end result is worth the effort.
