Key Features

• 98% UV Blocking: High-density PES fabric with PU coating filters out up to 98% of direct UV rays, protecting you and your family outdoors.
• Waterproof Performance (400 kPa): The PU-coated Oxford cloth construction resists water penetration — install at a 20–40° angle for proper runoff and no water pooling.
• Tear-Resistant & Durable: 160GSM fabric with reinforced stitching stands up to wind, sun, and rain for long-lasting outdoor use.
• Breathable Design: Air flows through the fabric structure to help reduce heat buildup beneath the canopy, keeping the shaded zone noticeably cooler.
• Versatile Fit: Rectangle shape works over patios, decks, pergolas, carports, garden areas, pool surrounds, BBQ zones, sandboxes, and more.
• Easy Installation: Corner D-rings are reinforced for secure attachment. Leave a 0.5–1 ft margin between fixing points and the sail edge for hardware, hooks, or ropes.
• Precision Manufacturing: Due to the nature of this waterproof polymer fabric, a ±2-inch dimensional tolerance is normal. Larger sizes may include a seam for structural integrity.

Frequently Asked Questions

Q: Is this rectangle shade sail truly waterproof, or just water-resistant?

A: This sun shade sail is rated at 400 kPa waterproof performance thanks to its PU-coated High-Density Polyester fabric. For best results, install the sail at a 20–40° angle so water runs off the surface rather than pooling. It offers solid waterproof protection for typical outdoor rain conditions.

Q: How much UV does this outdoor canopy block?

A: The shade sail blocks up to 98% of direct UV rays, making it highly effective at reducing UV exposure for people relaxing beneath it on sunny days.

Q: How do I install the rectangle shade sail?

A: Measure and clean the installation area first. Attach anchor points (posts, walls, or trees) and leave a 0.5–1 ft margin between each fixing point and the sail's corner D-ring for hardware or rope. Tilt the sail 20–40° for water runoff and tension it firmly for wind resistance. Larger size sails may include a seam, which is a normal part of construction for this waterproof fabric type.

Q: What size tolerance should I expect?

A: Due to the inherent properties of the PU-coated polymer fabric, a manufacturing tolerance of ±2 inches is normal and expected. Please account for this when planning your installation measurements.
