Today, it is probably difficult to name such areasConstruction, which would not have used various kinds of grids. But very few people know that their varieties are very many: 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 PVC coating, which is called a welded wire mesh with PVC-coating in the nomenclature.
This material is made in the form of a lattice ofsmooth or relief wires, the diameter of which is 0.6-5 mm. In the production can also be used fittings with a diameter of 6 to 12 mm, the application of which is perpendicular and carefully welded. Welded grid with PVC-coated can be made in maps, then the cell size is obtained from 5 to 200 mm. This type of metalmetallic products is used quite widely. It has found application in the implementation of fixing brick masonry, building walls, reinforcing pavement and reinforced concrete road structures.
Welded grid with PVC-coating - this is the usualWelded wire mesh, with the only difference being that in manufacturing it is immersed in molten polyvinylchloride. When it becomes necessary to purchase this product, you should pay special attention to 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 may arise in the future.
A layer of polyvinyl chloride, depending ontechnology, can have a thickness of 0.1-0.3 mm. When we are dealing with a popular grid with the parameters 50x50x2.2, then if the thickness of the coating is taken into account, the diameter of the wire itself can be only 1.9 mm, which can significantly affect the strength of the entire structure.
The welded mesh with PVC-coating, according tostatistics, most manufacturers are made with a diameter of 0.2-0.4 mm. Some in the documentation indicate a double diameter - core and outer diameter. In this case, an incorrect interpretation of the true thickness of the wire can have even more dramatic consequences. Usually such hardware products have PVC green.
It is useful to know that domestic and most foreign manufacturers pack these products with PVC coating in polyethylene, and, for example, Chinese ones - in thick paper.
Welded grid with PVC-coating is supplied inrolls, as a result of which it is convenient to transport. Anticorrosive properties are provided by the polymer layer, which, among other things, gives (in comparison with the conventional model) a more aesthetic appearance. Therefore, this product is often used in suburban construction.
Galvanized wire mesh with PVC-coating exists in two types: sectional and roll.
To all of the above, you can add that the material is not subject to harmful environmental influences and will not rust over time.
