Prairie nets are generally made of hot-dip galvanized wire

　　Prairie nets are generally made of hot-dip galvanized wire, and the amount of zinc applied is generally 60 to 100 grams per square meter. The requirement for wet areas is higher, and about 230 grams of wire is used. Recently, cold galvanized wire is also used in Africa. Horizontal wire, tensile strength 80KG-90KG to increase the impact resistance of the net. Vertical wire, low carbon steel wire with tensile strength 40KG-50KG so as to be wound on horizontal wire. (Add 2T-3T mechanical pressure during winding to prevent vertical wire from sliding)

　　 The flatness of the grassland net surface is required to be: no more than 1 up-and-down point (10 square centimeters) per 50-meter length, and no more than 10mm. The left and right error of the grid is not more than 3MM, and no joint is allowed on the horizontal wire of each roll of bullpen.
