OOTONAT 16'x20' Sun Shade Sail Curved Rectangular — Dark Grey, 185 GSM Heavy-Duty UV-Blocking 95%

This OOTONAT 16'x20' curved sun shade sail is a heavy-duty, 185 GSM permeable outdoor cover that blocks up to 95% of UV rays to create a cool shaded area for patios, decks, yards, and commercial spaces.

Give your outdoor space usable shade without sacrificing airflow or style. The OOTONAT shade sail combines high-density, UV-stabilized polyethylene fabric with reinforced stainless-steel D-rings, delivering a durable, breathable canopy that reduces heat and glare while allowing wind and rain to pass through. Its dark grey color and curved rectangular shape blend into residential and commercial settings, from backyard lounges to café patios.

How well does this sail protect from sun and heat?

The 185 GSM fabric is engineered to significantly reduce direct sunlight and harmful ultraviolet exposure while remaining breathable. It does not create a sealed environment—air and light diffuse through—so shaded areas stay cooler but ventilated, minimizing heat buildup beneath the sail.

• Blocks up to 95% of UV rays (UV-stabilized polyethylene)
• 185 grams per square meter density for strong sun defense
• Permeable weave reduces heat while allowing airflow
• Dark grey fabric lowers glare and complements many decors

Is the OOTONAT shade sail built to last outdoors?

Yes. The sail uses tightly woven, UV-resistant material and stainless-steel hardware to resist sun degradation and corrosion. Reinforced seams and corner D-rings help the canopy withstand tension and routine outdoor exposure when properly installed and maintained.

• 185 GSM UV-treated polyethylene resists fading and fiber breakdown
• Stainless-steel D-rings for durable anchor points
• Reinforced stitching at stress points for better load distribution
• Suitable for pergolas, carports, patios, parks, and commercial installations

How simple is installation and what mounting options work?

Installation is straightforward for homeowners and contractors alike: choose sturdy anchor points, maintain correct tension, and use appropriate hardware for the mounting surface. The sail’s corner rings allow flexible attachment to trees, posts, walls, or dedicated frames; using turnbuckles and pad eyes will help achieve tight, long-lasting results.

• Mount to trees, roof beams, concrete walls, or metal posts
• Compatible with common hardware: turnbuckles, snap hooks, pad eyes
• Follow a three-point or four-point layout for stable tensioning
• Quick-release methods make seasonal removal simple when needed

What should I expect in care and maintenance?

Routine care keeps the sail performing season after season: clean gently, avoid harsh chemicals, and remove the sail during severe storms or heavy snow. Properly tensioned and stored fabric will retain strength and color much longer than neglected covers.

• Hand or soft-brush wash with mild soap and water
• Rinse thoroughly and air dry before storage
• Lower or remove the sail for winter or major storms
• Inspect seams and hardware periodically for wear

Who is this for? The OOTONAT 16'x20' curved shade sail is ideal for homeowners, café and restaurant owners, landscape designers, and facility managers who need a durable, attractive shading solution that balances sun protection with airflow. Choose this sail if you want robust UV defense, flexible mounting options, and commercial-grade hardware for patios, gardens, carports, or public gathering areas.
