The shade sail is made of polyethylene raw material, adding a certain proportion of color masterbatch and other additives, drawing and warp knitting into a net, and then cutting and sewing. Due to the market reasons it faces, the requirements for shade sails are relatively high. The raw materials must be brand new color masterbatches with special color masterbatches. If ordinary color masterbatches are used, the color will fade rapidly and the color fading will be serious. The gram weight is generally above 180g. Secondly, the cutting of the shade sail must strictly comply with the proportion, to ensure that the size of the sail is sufficient, and the net surface is symmetrical and flat after being pulled up. Furthermore, the accessories of the shade sail mainly include D-rings, strong webbing, and long rope outer packaging bags.
