For the production of various kinds of fences, materials with a high strength factor are used. This is due to frequent loads from the wind, other physical influences, as well as those associated with an aggressive environment. A wide range of high-quality mesh and profiles for fencing can be purchased at http://metallica66.ru .
Mesh technology
Wire is used to make the mesh. Usually, it is made from low carbon steel, by drawing a thread of a certain diameter. The drawing is done through a special punch with a calibration hole. Depending on what grade of steel, what speed of drawing and what kind of calibration hole, you can get wire of different diameters.
As for the material, it is determined by GOST 23279-85. Sizes of finished products also depend on what material is used for their manufacture. For the most part, ordinary steel St3 is used, with various anti-corrosion additives and fluxes.
To prevent severe corrosion of the mesh, the technology of electroplating or coating with composite (rubber) materials is also used. In some versions, the mesh can be made of high-carbon steels such as 12X18H10T or 08X18H10. These materials give the finished product high strength, low flexibility and great durability.
Rolled steel production technology
Another widespread type of fencing is a metal profile. In general, the profile is made by stamping or broaching. The material is carbon steel, which undergoes an anti-corrosion coating.
Steel for the manufacture of rolled products are such grades as C235, C245, C255 and so on. The steel with the limiting carbon content for dies is C375.
