AsterOutdoor Triangle Sun Shade Sail 16' x 16' x 22.64' Graphite — 95% UV Block, Breathable HDPE Canopy

The AsterOutdoor Sun Shade Sail Triangle 16' x 16' x 22.64' is a lightweight, durable outdoor canopy that blocks up to 95% of UV rays and creates breathable shade for patios, yards, and events.

This triangle shade sail combines high-density polyethylene fabric, reinforced stitching and stainless steel D-rings to deliver reliable sun protection without trapping heat. Its curved-edge triangle profile resists sagging and keeps tension across the fabric, while included polyethylene ropes make it straightforward to secure between posts, trees, or existing structures. Available in graphite and other neutral tones, the sail packs small for storage and travel and is designed for everyday outdoor living spaces.

How much sun protection does this shade sail provide?

The sail is made from 185 GSM high-density polyethylene fabric engineered to block approximately 95% of UV radiation. Its breathable weave lets air pass through, reducing heat buildup beneath the canopy while still significantly reducing sun exposure.

• Fabric: 100% HDPE, 185 GSM for durable UV resistance
• UV block: up to 95% blockage of harmful rays
• Breathability: allows airflow to keep shaded areas cooler
• Design: curved triangle sides for even tension and less sagging

How do I install and tension the triangle shade sail?

Set up requires three strong anchor points—posts, trees or fixed structures—and the included polyethylene ropes. Attach the sail’s stainless steel D-rings to your anchors, leave 1.5–2 feet between the sail and fixings for hardware or turnbuckles, and tighten evenly to achieve proper tension.

• Hardware: stainless steel D-rings sewn into each corner
• Ropes: three 5-foot polyethylene ropes included for secure attachment
• Clearance: leave 1.5–2 ft between sail and anchor point for fittings
• Tip: tighten gradually and adjust each corner to prevent wrinkles

What maintenance will keep the canopy lasting longer?

Light maintenance keeps the fabric performing and looking good. Avoid exposure to harsh chemicals like chlorine that can weaken fibers, and clean with a garden hose or gentle scrubbing using mild soapy water; do not machine wash or tumble dry.

• Cleaning: rinse with hose or gently scrub stains with mild soap
• Storage: fold dry and store in original bag to prevent mildew
• Chemicals: avoid chlorine and harsh solvents that degrade fabric
• Inspection: periodically check D-rings and ropes for wear

Will this shade sail hold up to everyday outdoor use?

Built for residential and casual commercial settings, the AsterOutdoor sail balances strength and portability for patios, decks, poolsides and event areas. Reinforced seams, durable fabric and stainless steel fittings make it suitable for seasonal use and frequent setup, though it’s recommended to remove the sail during severe weather.

• Construction: reinforced stitched seams and sturdy D-rings
• Portability: lightweight and compact for easy transport in backpacks
• Durability: designed for routine outdoor exposure and events
• Weather: remove in high winds or heavy storms to prolong life
