Grassland fence, also known as cattle fence, are a kind of ecological balance widely used in America and Europe to prevent landslides, animal husbandry fences, especially in rainy mountain areas. A layer of sunscreen 120 g nylon woven cloth is sewn outside the net to block mud and sand So outflow has developed rapidly in recent years.
Full automatic mechanical production features: save a lot of labor, reduce the labor intensity of workers, add 2T-3T mechanical pressure during winding to make the net surface smooth, the structure is firm and precise, the mesh is uniform, and the integrity is strong. In particular, an advanced pressure wave process is used to press a deep 12MM wide and 40MM bend between each grid. This bend is commonly known as “wave” to make the mesh surface smoother, which eases thermal expansion and contraction in winter and summer climate change regions and prevents When there is a beast, the net surface will automatically return to increase the cushioning force of the net surface.
Grassland fence are usually made of hot-dip galvanized wire. The amount of zinc is generally 60 grams to 100 grams per square meter. The requirements for wet areas are higher. The wire is about 230 grams. 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 of 40KG-50KG so as to be wound on horizontal wire. (Add 2T-3T mechanical pressure during winding to prevent the vertical wire from sliding)
The flatness of the grassland fence surface is required to be flat: every 50 meters long, the ups and downs should not exceed 1 (10 square centimeters), and the ups and downs should not exceed 10MM. The error of the left and right of the grid does not exceed 3MM, and no joints are allowed for each roll of the cattle fence.
