ColourTree Custom Size 9ft x 18ft x 20.1ft Blue Right Triangle Sun

In this review the ColourTree 9' x 18' x 20.1' blue right triangle sun shade sail is assessed for backyard and commercial use; it is best for buyers who need a heavy duty, breathable UV cover that resists sun damage. The single biggest reason to consider this sail is its thick 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says was lab-tested for extended sunlight exposure and is intended to last longer than recycled alternatives.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric delivers a sturdy feel and is designed to resist tearing under regular sun exposure.
• UV stabilized compound: Laboratory UV testing and treatment reduce drying and fading so the canopy keeps usable life in sunny installations.
• 95% UV blockage: The woven fabric blocks most harmful UV and helps lower temperatures in the shaded area for patios, pools and carports.
• Breathable woven construction: Air and water pass through freely to avoid pooling on rainy days while still providing shade.
• Reinforced edges and D-rings: Heavy double-stitched seams and stainless steel D-rings at each corner support secure attachment and reduce fraying.
• 3 year limited warranty: A limited warranty covers normal weather and usage, offering buyers reassurance about expected durability.

Who It's For

This shade sail is well suited to homeowners or small businesses who need a robust sun cover for patios, above-ground pools, carports, balconies or commercial outdoor seating. Installers who prefer a breathable fabric that avoids water pooling and who will use proper hardware will benefit from the sail's reinforced corners and heavy stitching.

Those needing a precise prefabricated size beyond the listed 9' x 18' x 20.1' or buyers who expect extreme wind or abrasive conditions should consider alternative mounting methods or more specialized wind-rated canopies, since installation hardware and anchoring quality will strongly affect performance.
