ColourTree Custom Size 17ft x 24ft x 29.4ft Right Triangle Sun Shade

In this review the ColourTree custom size right triangle sun shade sail is assessed for homeowners and small commercial users who need robust sun protection over irregular outdoor areas. The primary reason to consider it is the use of a thick 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the reviewer found delivers noticeably stronger construction and longer resistance to sun damage than thinner recycled alternatives. For anyone prioritising long-term UV blockage and a breathable fabric that sheds water, this shade sail stands out.

Key Features

• 190 GSM Virgin HDPE: The heavy 190 GSM material offers a dense weave that feels substantial and is designed to resist tearing under regular outdoor exposure.
• UV Stabilized Compound: Laboratory testing up to 20,000 hours is cited for the treated fabric, helping prevent drying, fading and premature failure from sunlight.
• 95% UV Blockage: The woven fabric blocks most harmful UV and noticeably reduces heat beneath the sail, improving comfort for patios and pools.
• Breathable, Water-Shedding Weave: The mesh allows air and water to pass through so rain does not pool on the surface, reducing stress on fastenings.
• Reinforced Edges and Stainless D-Rings: Double layered stitched seams and heavy stitching at corners secure the stainless steel D-rings for reliable anchoring.
• Commercial Heavy Duty Build: The construction is intended for heavier duty use, with a three year limited warranty under normal conditions.

Who It's For

This shade sail is well suited to homeowners with patios, balconies or above-ground pools who need a large custom-sized triangle to cover awkward layouts, and for small commercial venues seeking a breathable, long-lasting shade solution. Installers and DIYers who can attach the sail to sturdy poles, walls or trees and who use proper hardware will see the best performance.

This product is less appropriate for those who need an all-weather waterproof canopy, since the fabric is breathable and allows water through rather than creating a sealed roof. Also, buyers who cannot provide proper marine-grade cables or appropriate anchor points should look for complete hardware-inclusive kits rather than this fabric-only offering.
