The construction is obtained interlacing the wires that form habitually squared mesh,with constant lights. They are produced habitually in panels. Used in the winnowing of products abrasives, it is made of wires in carbon steel with particular mechanical resistance.
To be fixed to winnowing systems, this net is usually supplied whit reinforced couplings at 15° - 30° - 45° - 90°.
To calculate the useful passage surface is habitually used the following formula: [(MESH OPENING)2/(MESH INTERAXIS)2]*100

Legend:
L = Mesh Opening in mm D = Wire Diameter in mm P = Weight Kg / Sq.Mt. * = Theoretical weight for steel
