ColourTree 12' x 12' x 17' Grey Right-Triangle Sun Shade Sail — 190 GSM HDPE, Blocks 95% UV

ColourTree’s 12' x 12' x 17' grey right-triangle sun shade sail is a commercial-grade, breathable HDPE canopy that blocks up to 95% of UV, resists water pooling, and includes reinforced corners for secure mounting.

Made from 190 GSM 100% virgin HDPE with UV-stabilized compounds, this right-triangle shade sail is built for long-term outdoor use. Laboratory-tested against sunlight degradation, the fabric is designed to resist fading, tearing, and drying; stainless steel D-rings and double-layer stitched seams give it structural strength for patios, pools, carports, playgrounds and commercial installations. Installation hardware is sold separately, and ColourTree offers a 3-year product support service plus custom sizing options.

How does this shade sail perform in strong sunlight and rain?

The tightly woven HDPE mesh blocks approximately 95% of UV radiation while remaining breathable, so it reduces temperature under the canopy without trapping moisture. Rainwater passes through the fabric rather than pooling, lowering stress on seams and supports.

• 190 GSM virgin HDPE mesh for high UV resistance and durability
• Breathable woven structure lets air and water pass through
• Tested for extended UV exposure to limit fading and brittleness

What makes the construction durable enough for commercial use?

Durability comes from multiple design details: double layered reinforced edges to prevent fraying, extra-heavy stitching at corners, and rust-resistant stainless steel D-rings at each corner for secure connections. These features reduce fabric deformation and extend useful life under regular outdoor stress.

• Reinforced stitched seams along all edges to prevent edge failure
• Stainless steel D-rings at each corner for reliable anchoring
• Extra-heavy corner stitching to transfer load to the attachment points

How should I install and maintain the ColourTree shade sail?

Installation requires separate hardware kits and appropriate anchor points such as poles, walls, or trees; do not use nylon rope, which can snap. For longevity, tension the sail evenly and allow drainage by tilting the canopy to prevent sagging. Routine checks of anchors and stitching are recommended after storms.

• Use shade sail hardware kits and cable rope (sold separately) for best performance
• Avoid nylon rope—use steel cable or marine-grade fittings
• Tension sail and angle it slightly to facilitate water runoff
