The shade sail is made from 200 GSM HDPE and is built to block up to 95% of UV rays, so the single biggest reason to buy is long-lasting sun protection with a measured design that reduces mid-sagging. Installation is straightforward for anyone comfortable with basic mounting hardware, and custom sizing and a 3-year warranty add reassurance.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner-to-corner measurement:\u003c\/strong\u003e The sail is measured from corner to corner and crafted with slightly curved edges so the fabric sits tight and neat after installation, avoiding mid-sagging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200 GSM HDPE construction:\u003c\/strong\u003e The woven knitted design is breathable and helps prevent water pooling while resisting UV degradation and fading for extended outdoor use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh UV protection:\u003c\/strong\u003e Designed to block up to 95% of harmful UV rays, it reduces direct sun exposure and can lower temperatures beneath the canopy by about 15 degrees compared to unshaded areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless steel D-rings:\u003c\/strong\u003e Heavy-duty D-rings on each corner simplify attachment to posts, roofs, trees, or walls and are reinforced with extra stitching for strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge reinforcement:\u003c\/strong\u003e Double-layer stitched edges prevent fraying and preserve the sail's shape through repeated tensioning and use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom sizes and warranty:\u003c\/strong\u003e Available as a custom-size made-to-order product with 30-day returns and a 3-year limited warranty against UV failure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Royal Shade 12' x 21' Green sail is best for homeowners, patios, carports and small commercial spaces that need broad sun protection and a neat installed appearance.
