They are made of yarn or roving by means of leno or plain weave.The diameter of elementary glass fibres varies between 9 and 17micron. Mesh fabrics combined with specially designed mesh surface treatments can be used in a wide range of applications, but are mainly used in construction industry. Surface treatments based on styrene-butadiene ensure alkali resistance and increase the mechanical durability that is required by the construction industry. In addition, other surface treatments based on pvac , pvc or styrene-acrylate are used for different.
