Custom Size 18ft x 19ft x 26.2ft Right Triangle Sun Shade Sail - UPF50

In this review of the 18' x 19' x 26.2' right triangle sun shade sail, the bottom line is simple: this sail is for anyone who needs a heavy-duty, customizable sun cover that blocks most UV while staying breathable. The reviewer found the 200 GSM HDPE fabric and reinforced stainless D-rings deliver a robust, long-lasting canopy ideal for patios, chicken runs, or commercial outdoor seating. Its clear strength is sun protection and temperature reduction, making outdoor spaces noticeably cooler without trapping air or water.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays for safer prolonged outdoor use.
• Temperature reduction: The sail can lower temperatures by up to 15 degrees compared to unshaded areas, improving comfort under the canopy.
• Commercial-grade construction: Reinforced edges, double-layer stitching, and stainless steel D-rings resist fraying and hold up under repeated tension.
• Custom fit: Measurements are taken D-ring to D-ring so the sail can be made to your precise layout and attachment points.
• Breathable and water permeable: The material allows air and water to pass through, avoiding puddling and reducing wind load.
• Three-year assurance: The product includes a 3-year assurance that reflects the manufacturer confidence in build quality.

Who It's For

This shade sail is best for homeowners, small businesses, or hobby farms that need a tailored shade solution where standard sizes do not fit. It suits patios, pergolas, poolside areas, outdoor dining, and animal enclosures where UV protection and cooler temperatures matter.

Those looking for a fully waterproof canopy, a permanent solid roofing solution, or a very large uninterrupted shading surface may want to consider alternative products; this sail is designed as a breathable, tensioned fabric shade rather than a rigid roof.

Frequently Asked Questions

How do I measure for a custom sail?
Measure from D-ring to D-ring at the points where the sail will attach and allow the recommended gap near posts or anchors for tensioning.

Will it stop rain?
The fabric is water permeable so it sheds some water but will not provide a fully waterproof roof in heavy rain.

Is installation difficult?
Installation is straightforward for a handy person using mounting hardware; ensure corners have proper gap for tension and use sturdy anchor points.
