The order on the plot begins with a solid beautiful reliable fence and gate. In order for the fence to meet the highest requirements, it is made of materials with good technical characteristics. A metal column is the basis of a reliable design. In order to choose it correctly, it is necessary to understand the technical characteristics of metals.
Understand what diameter is necessary to hold different types of spans of the fence, the size and weight of the gate wings. But not every developer has such knowledge. This article is written to help lay people.
As a building material, a metal pillar is divided into two types. The first of these is a steel pipe that meets certain GOSTs. Let's make a small digression, or rather give a recommendation. In our country, GOST has become an optional condition. Any products must comply with technical specifications (technical specifications), that is, be made of materials that have the minimum acceptable technical characteristics. GOST became a voluntary affair. But so far, the products manufactured on it are the highest quality product. A fence and a gate is a serious matter, therefore, it is not recommended to purchase a metal pole made according to TU for their construction. So, we go further. The pipe for fencing should be produced in accordance with GOST, which satisfies a number of technical requirements. The metal column for the fence may be in the shape of a square or rectangle. Hooks or straps are often welded to it over the entire length in two or three places. The first are necessary for fixing the mesh-netting. On the second, sections of the fence made of wood and metal profile are fixed .
The metal pole must be at least two meters long. This characteristic should be increased if the distance between the fence posts is more than one and a half meters. In most cases, 60x60 metal posts are used to erect fences. Another no less important condition is the load bearing. It should be distributed evenly.
But no matter how reliable the metal, it is very susceptible to corrosion. To protect against it, the metal post must be cleaned and rusted after installation. Do not leave the top of the pipe open. Usually it is brewed with metal lids. Recently, manufacturers offer ready-made fence posts, closed with plastic plugs. This greatly facilitates the task of maintaining the integrity of the pipe.
Reliability and quality are, of course, paramount concepts. But I want to see my personal plot beautiful with a harmoniously fitting fence. Therefore, decorative metal poles are increasingly appearing in the building materials market. To give them an unusual and interesting look, various figures are welded to the upper part of the pipe: balls, forged branches, rhombuses. Such racks are either sold separately, or included in the systems of decorative complexes. Of course, such fences are more aesthetic, but their price is corresponding.
