ColourTree Custom Size 20ft Triangle Sun Shade Sail - Heavy Duty UV

In this review the ColourTree 20' x 20' x 20' grey triangle sun shade sail is examined for homeowners and small commercial spaces seeking a durable, high-coverage shade solution. The single biggest reason to buy is its thick 190 GSM virgin HDPE fabric that is UV stabilized and laboratory tested for longevity, making it a sensible choice where strong sun exposure demands a long-lasting canopy rather than a cheap seasonal cover.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric gives noticeably firmer feel and resists tearing better than lighter recycled sails.
• UV stabilized compound: Material went through extended UV testing so it resists drying, fading and brittleness in hot sun for longer service life.
• 95% UV blockage: The woven fabric cuts most harmful UV and immediately reduces radiant heat under the canopy for more comfortable outdoor use.
• Breathable weave: Air and water pass through the fabric to prevent pooling and reduce wind stress, making it suitable for unpredictable weather.
• Reinforced edges and stainless D-rings: Double layered seams and heavy stitching keep edges from fraying while D-rings provide secure anchor points for installation.
• 3 year limited warranty: Manufacturer warranty covers normal weather use and underlines the intended lifespan compared with lower grade sails.

Who It's For

This large triangle shade sail is ideal for homeowners with a patio, poolside area, balcony or carport who need broad, angled coverage and want a product built for sun-heavy climates. It is also a good fit for small commercial sites such as cafes or playgrounds that require a robust fabric that resists fading and tearing.

Customers looking for a do-it-yourself quick clip canopy or lightweight temporary cover should look elsewhere; this sail requires separate installation hardware and correct tensioning with cables and strong anchors to perform as intended. It is not a waterproof canopy for prolonged downpours.
