Artpuch 12'x12'x12' Triangle Sun Shade Sail — Dark Grey HDPE, UV 95% Block, Breathable Wind-Resistant

The Artpuch 12' x 12' x 12' dark grey triangle sun shade sail is a heavy-duty HDPE canopy that blocks up to 95% of UV rays while allowing airflow for cooler, wind-resistant outdoor coverage.

This triangular shade sail is built for outdoor living: woven high-density polyethylene (HDPE) fabric with UV-inhibiting additives, reinforced corners and stainless steel D-rings provide a reliable sun protection solution that resists fading and tearing. It’s breathable to prevent heat buildup and pooling, and its dark grey tone offers a modern, low-glare look that complements patios, decks, pools and play areas. Note that the hardware kit is sold separately and the sail’s measurements can vary slightly.

How well will this sail protect my patio from sun and heat?

The HDPE material is treated to reflect and filter sunlight, reducing direct UV exposure and lowering localized heat beneath the canopy. It won’t cool like a solid roof, but by blocking up to 95% of UV rays it significantly reduces sun intensity and protects surfaces and furnishings.

• UV resistance: blocks up to 95% of harmful UV rays
• Fabric: high-density polyethylene with UV-inhibiting particles
• Color: dark grey reduces glare and complements outdoor decor

Can the shade sail handle wind and rain?

The sail is designed to breathe—air flows through the woven fabric so wind loads are dispersed and water won’t pool. For best performance in breezy conditions, install the sail with one corner higher to create a 30° angle so water drains off and wind is guided over the canopy.

• Breathable weave reduces flapping and wind pressure
• Recommended 30° installation angle to shed water
• Strong corner reinforcements and stainless D-rings for secure anchoring

What size and fit considerations should I know before buying?

Measure the distance between the mounting points while the sail is stretched; allow an extra 1.5–2 feet for tensioning hardware and turnbacks. Expect a manufacturing tolerance of about ±4 inches, and if you need a nonstandard size, Artpuch offers customization to match unique layouts.

• Measure between D-rings when stretched for accurate fit
• Leave 1.5–2 feet for attachments and tensioning
• Manufacturing tolerance: ±4 inches; custom sizing available

Is installation hardware included and how is it mounted?

The sail ships without a hardware kit, so you’ll need to purchase suitable anchors, turnbuckles, shackles or posts separately for a strong installation. Use corrosion-resistant stainless or galvanized fittings and tighten gradually to achieve even tension across all three corners.

• Hardware kit sold separately—select marine-grade or galvanized fittings
• Install anchor points on beams, poles, walls or certified eye bolts
• Tension evenly to avoid distortion and ensure long life
