High-Quality Material: Made of high-density woven fabric (HDPE), it's more resistant to wear, tear, and corrosion while providing excellent sun protection and effectively blocking 98% of UV rays. Advanced Technology: Dedicated to providing top-quality sun sails, great attention is paid to every process. Each edge features two/three layers of webbing (2.5cm, 18g/m) to prevent tearing, and its stainless steel D-rings are rounded with four curves at each corner for a more secure fit. Stable Construction: Arched edges, stainless steel D-rings, rope attachment, reinforced with quadruple twill weave, and double layers of fabric between the ring and sail contribute to increased stability during use and throughout the sail's lifespan. Easy Installation: Easily install the sun sail using sturdy rope. We recommend a 20-40 degree mounting angle for optimal tension, helping to keep it taut. Perfect for patios, balconies, gardens, pools, camping, lawns, parking areas, or other outdoor spaces.
