Lightweight and Durable Rectangular Shade Cloth: The shade sail is made of high-quality high-density polyethylene with a smooth and flat surface, lightweight and flexible, easy to fold, and with good resistance to aging and corrosion. Quality Shade Cloth: Shade nets block more than 90% of the sun's rays but do not prevent the passage of water and air. Rectangular shade cloths have a significant cooling and shading effect, creating a cool and comfortable environment. Shade sails also prevent the sun from burning plant leaves, and we can water plants directly through the garden shade, which helps reduce water evaporation. Multifunctional Shade Cloth: Rectangular sunscreen cloths can also be used on patios as windbreaks and privacy screens. When placed over a pond, shade sails are effective at reducing pond temperatures and preventing excessive algae growth, as well as preventing dead leaves from falling into the pond. Shade sails also prevent wind, snow, and heat from penetrating.
