ColourTree Custom Size 18ft x 18ft x 25.5ft Red Right Triangle Sun

In this review of the ColourTree custom size red right triangle sun shade sail, the bottom line is clear: this is for homeowners and small commercial spaces that need a durable, high-coverage shade solution with strong UV protection. The single biggest reason to buy is the heavy duty 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers extended outdoor life and reliable sun blockage where a long-lasting, breathable canopy is required.

Key Features

• 190 GSM virgin HDPE: The thick 190 GSM non-recycled fabric provides a sturdier feel and more resistance to wear than thinner recycled alternatives, helping the sail maintain shape under sun and wind.
• UV stabilized compound: Treated material resists drying, tearing and fading after prolonged sun exposure, extending useful life in outdoor installations.
• 95% UV blockage: The woven fabric blocks most harmful UV rays and noticeably reduces temperature in shaded areas, making it practical for patios, pools and carports.
• Breathable mesh construction: The weave allows air and water to pass through, preventing water pooling and improving comfort beneath the sail during warm weather.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings provide durable anchor points and reduce the chance of frayed edges or distorted shape.
• 3 year limited warranty: The sail carries a limited warranty covering normal weather and usage, offering additional confidence for long-term outdoor use.

Who It's For

This shade sail is best for homeowners, rental property owners, and small businesses that need a customized triangular canopy for patios, pools, balconies or carports and value long-term UV resistance and color retention. It works particularly well when a true 90 degree corner or triangular mounting points are available, and for buyers who prefer a bold red color as a design feature.

It is less suitable for buyers who need a ready-to-install kit with ropes and hardware included, since installation hardware is sold separately, or for those who want a lightweight temporary sunshade for occasional use rather than a commercial heavy duty solution.

Pros & Cons

Pros

• Durable 190 GSM virgin HDPE material holds up well under intense sun and resists fading.

• Reinforced seams and stainless steel D-rings make mounting secure and long lasting.

• Installation hardware is not included, so buyers must purchase proper cables and fittings separately.
