The screen tensioner produced by our company adopts high quality steel plate as cleat, which has good tensile strength and fixity. The gears are made of high quality aluminum alloy. Tensioner production In order to achieve better tightening line effect, we repeatedly improve the design and adjust reasonable size, from plate thickness to large size. In order to reduce the corrosion rate of the product, we use Q195 steel, and the surface treatment adopts advanced Dacromet surface treatment technology, the surface treatment process is better than electro-galvanization.
