1. Material: High density polyester shade sail with waterproof coating (220gsm), water and tear resistant, but not recommended for use in heavy rain or extreme weather conditions. 2. UV Protection: Our shade sail prevents harmful UV rays from passing through the awning. Enjoy a safe and cool space for you and your family in the garden or on the terrace. 3. Lightweight but strong fabric: Double-edged seams and stainless steel D-rings provide stability and strength, making both sides more sturdy. (Note: The shade sail is usually a collection of two or three pieces of fabric sewn together, not a single piece.) 4. Simple and safe installation with rope or fixing kit. We suggest that the installation angle is 20 to 40 degrees, in order to obtain maximum tension and allow rain to run off. Contents: 1 shade sail (waterproof, rectangular)
