It is a plate-shaped mesh with diamond-shaped holes formed by punching and stretching metal plates. Common materials include aluminum plate mesh, aluminum foil mesh, copper plate mesh, stainless steel plate mesh, nickel plate mesh, and titanium plate mesh. Common terms Short pitch (SWD): The length of the short diagonal of the diamond-shaped hole from the center of the node to the center of the node. Long pitch (LWD): The length of the long diagonal of the diamond-shaped hole form the center of the node to the node. Short pitch (inner hole) (SWO): The length of the short diagonal hole (as shown in the figure). Long pitch (inner hole) (LWO): The length of the long diagonal hole (as shown in the picture). Strand: The width of the edge of the diamond-shaped hole of the steel mesh is the length of the metal plate used to make one strand. Bond: The connection point of two strands. Thickness: The thickness of the original steel plate. Roll: Indicates the specific length and width of the rolled steel mesh. Sheet: Indicates the specific length and thickness of the steel mesh.
