The utility model relates to a net sheet of a windproof net. The net sheet uses Q195 cold rolled steel plates as materials. Meshes of the net sheet mainly use small round holes, big round holes, long holes and sloping long holes as ventilation holes. The ventilation rate of the utility model is 43%. The utility model has better windproof effect. The net sheet forms a butterfly shape by four folds, and the windproof strength of the net sheet is increased. The net sheet uses cold rolled plates with the thickness of 1.2 mm, so that the cost of the whole project of windproof nets can be reduced. The inner surface and the outer surface of the net sheet are processed by hot galvanizing, the utility model can resist wind, rain and intense ultraviolet, and the service life of the net sheet can be effectively extended.
