Galvanized wire mesh plays a certain role in building thermal insulation and crack prevention projects. The exterior wall plastering mesh is divided into two types: one is hot-dipped galvanized wire mesh (long-lasting life, strong corrosion resistance); the other is modified wire mesh (economical, even surface, white and glossy). Selection of materials is reasonable based on the region and the requirements of the construction unit. The specifications of the wire mesh used in plastering construction are mostly 12.7×12.7mm, 19.05×19.05mm, 25.4×25.4mm, with wire diameters ranging from 0.4 to 0.9mm.
