About this product High-quality material: Thanks to the high-density fabric (HDPE), HAIKU's sun sail (185 g/m) is more durable, tear-resistant, and heat-resistant. It is corrosion-resistant, yet can offer good sun protection by effectively blocking ultraviolet radiation. Advanced technology: HAIKU strives to deliver high-quality sun sails and places great importance on every procedure. Each edge of the product has two/three layers of webbing (2.5 cm, 18 g/m) to prevent tearing. The stainless steel D-rings and four cover threads in each corner make installation safer. Stable construction: Curved edge, stainless steel D-rings, fastening ropes, four-layer twill reinforcement, and double fabric between the rings and the sun sail help to increase the sun sail's stability during use and its lifespan. Easy to install: You can easily install the sun sail using the fastening ropes. We recommend an installation angle of 20 to 40 degrees for maximum tension on the sun sail. Ideal for patio, balcony, garden, pool, camping, lawn, parking lot, or other outdoor spaces.
