Custom Size Right Triangle Sun Shade Sail Canopy 12ft x 17ft x 20.8ft

In this review the ColourTree custom size right triangle sun shade sail is evaluated for homeowners and small businesses who need a durable, high UV protection canopy. The bottom line is that this shade sail is best for those seeking a heavy duty, breathable cover that blocks most sunlight while allowing air and water to pass through; it stands out because the fabric is 190 GSM 100% virgin HDPE treated with a UV stabilized compound, which the maker says improves longevity under sun exposure.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric is designed to resist drying out and tearing, providing a robust canopy material for long-term outdoor use.
• UV stabilized compound: Laboratory UV testing and treatment help the fabric resist fading and degradation when exposed to sunlight.
• 95% UV blockage: The woven material blocks most harmful UV rays and reduces temperature under the canopy for cooler shaded areas.
• Breathable, water-permeable weave: The mesh lets air and rainwater pass through so there is no pooling and less wind load compared with solid covers.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy stitching at corners improve attachment strength and prevent fraying.
• Commercial heavy duty design: Intended for patios, pools, balconies and carports where a sturdy, long-lasting shade is required.

Who It's For

This shade sail suits homeowners, pool owners and small commercial locations that need a high UV block canopy with durable material. The thick 190 GSM virgin HDPE and UV stabilization make it a sensible choice for sunny climates where fabric longevity and strong seams matter.

It is less suited to buyers who want a fully waterproof awning, a quick temporary tarp, or who cannot provide proper anchor points and compatible hardware kits; installation requires separate hardware and correctly rated cable or rigging for best performance.

Pros & Cons
