ColourTree Custom Size Red Right Triangle Shade Sail 18ft x 21ft x

In this review the ColourTree custom size right triangle shade sail is assessed for homeowners and small businesses seeking heavy duty UV protection with a vivid color option. The bottom line: this sail is for anyone who needs a robust, breathable canopy that blocks up to 95% of UV while standing up to continuous sun exposure, because its 190 GSM 100% virgin HDPE and UV stabilized compound deliver noticeably better durability and color retention than typical recycled options.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled material provides a firmer, longer-lasting fabric that resists tearing and stretching over time.
• UV stabilized compound: Laboratory UV testing shows the fabric endures prolonged sun exposure without drying out or fading, which preserves both strength and appearance.
• 95% UV blockage: The woven mesh dramatically reduces sunlight and heat in shaded areas, making patios and pools noticeably cooler.
• Breathable, water-permeable weave: The fabric allows air and water to pass through so rain does not pool on the canopy and wind loads are reduced.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners keep the sail in shape and make attachment points durable.
• 3 year limited warranty: The warranty covers normal weather and usage, adding confidence for long-term outdoor installations.

Who It's For

This shade sail is ideal for homeowners, pool owners, cafes and small commercial spaces looking for a commercial heavy duty canopy that combines strong sun protection with a bold color. It suits installations where breathable fabric and long-term UV resistance matter, such as patios, balconies, carports and true 90 degree corner attachments.

Those seeking an all-inclusive installation kit should look elsewhere, because mounting hardware is sold separately and each D-ring requires a dedicated cable rope; installers will need to supply or buy appropriate shade sail hardware for a secure setup.
