Today, it is probably difficult to name such areas of construction in which various kinds of nets would not be used. But few people know that there are a lot of their varieties: from welded and woven or woven filtered to welded reinforced, copper and even nickel. And this is not the whole list. This article will describe in detail about the type of product with an additional special polyvinyl chloride coating, which is called a welded mesh with PVC coating according to the nomenclature.
This material is made in the form of a lattice of smooth or embossed wires, the diameter of which is 0.6-5 mm. In production, reinforcement with a diameter of 6 to 12 mm can also be used, the application of which is carried out perpendicularly and carefully welded.
Welded mesh with PVC coating can be made in cards, then the cell size is from 5 to 200 mm. This type of metal products is used quite widely. He found application in the implementation of fixing masonry, building walls, reinforcing road surfaces and reinforced concrete road structures.
Welded wire mesh with PVC coating is an ordinary welded wire mesh, with the only difference being that it is immersed in molten polyvinyl chloride during manufacture. When it becomes necessary to purchase this product, you should especially carefully look at the diameter of the wire. According to statistics, consumers pay little attention to the fact that the diameter guaranteed by the manufacturer is often indicated taking into account the coating itself, as a result of which various misunderstandings can arise in the future.
The polyvinyl chloride layer, depending on the technology, may have a thickness of 0.1-0.3 mm. When we are dealing with a popular mesh with parameters 50x50x2.2, then if the thickness of the coating is taken into account here, the diameter of the wire itself can be only 1.9 mm, which can significantly affect the strength of the entire structure.
The PVC-coated welded mesh, according to statistics, is produced by most manufacturers with a diameter of 0.2-0.4 mm. Some in the documentation indicate a double diameter - core and outer. In this case, an incorrect interpretation of the true thickness of the wire can have even more dramatic consequences. Typically, such hardware products have green PVC.
It is useful to know that domestic and most foreign manufacturers pack the specified products with PVC coating in polyethylene, and, for example, Chinese - in thick paper.
Welded wire mesh with PVC coating is supplied in rolls, making it convenient to transport. Corrosion-resistant properties are provided by a polymer layer, which, among other things, gives (in comparison with the usual model) a more aesthetic appearance. Therefore, this product is often used in summer cottage construction.
There are two types of galvanized mesh with PVC coating: sectional and rolled.
To all of the above, we can add that the specified material is not subject to harmful environmental influences and does not rust over time.
