The steel wire mesh (welded mesh) used for inner and outer walls is different, and the specifications of the steel wire mesh for inner walls are commonly used by construction units. The mesh size is the same, 1/2 inch=1.27cm, with a wire diameter of 0.3-0.5mm for the inner wall and 0.4-0.9mm for the outer wall, all according to the requirements of the construction unit for the steel wire mesh.
The steel wire mesh used for building plastering, also known as welding mesh, is divided into hot-dip galvanized steel wire mesh and ordinary plastering steel wire mesh. According to personal summary, these two types of steel wire mesh should be used in half and half of wall plastering and painting projects. Some projects may choose ordinary steel wire mesh due to financial considerations, while others may choose hot-dip galvanized steel wire mesh with good service life and strong anti-corrosion ability due to construction quality considerations.
