Shade&Beyond Triangle Sun Shade Sail 20'x20'x20' Dark Grey — 185gsm HDPE, 85–88% Sun Protection

This triangular shade sail from Shade&Beyond is built with 185 gsm HDPE fabric engineered to reduce solar heat while allowing airflow. Designed with reinforced seams and stainless steel D-rings at each corner, the sail resists tearing and disperses stress across anchor points. The fabric is permeable so it won't trap wind or moisture, and the curved edges help runoff instead of pooling. It arrives as the 20' x 20' x 20' triangle in dark grey, and Shade&Beyond can also make custom sizes to fit irregular spaces.

How much sun and UV protection will this shade sail provide?

The sail blocks a substantial portion of direct sunlight while still permitting air to flow beneath it. Expect around 85%–88% sunshade and about 95% filtering of harmful UV rays, making outdoor areas cooler and more comfortable during bright days.

• Fabric density: 185 gsm HDPE for consistent shading
• UV filtration: approximately 95% reduction of harmful UV exposure
• Shade coverage: roughly 85%–88% light blockage
• Permeable weave reduces heat buildup under the sail

What materials and hardware features ensure durability?

This sail combines heavy-duty HDPE fabric with reinforced stitching and stainless steel D-rings to endure regular outdoor use. While the material is resilient and resists fraying, the sail is not waterproof; the design prioritizes breathability and drainage over complete water resistance.

• 185 gsm high-density polyethylene for strength and longevity
• Well-stitched seams to prevent unraveling under tension
• Stainless steel D-rings at each corner for secure anchoring
• Curved edges to channel water away and reduce pooling

How should I measure and install the shade sail correctly?

Measure from D-ring to D-ring when planning your installation, and allow extra space for installation hardware. A common recommendation is to size the sail to about 88% of the area you will cover to keep a taut, neat appearance; hardware is not included, so select appropriate anchors for your mount points.

• Measure corner-to-corner (D-ring to D-ring) for accurate fit
• Allow 1.5–2 feet of clearance for turnbuckles and mounting hardware
• Consider sizing sail to ~88% of opening dimensions to avoid sagging
• Remove the sail during severe weather to protect it and anchors

How do I care for and maintain this shade sail?

Routine care is simple: check anchor points, clean debris, and store or remove the sail in extreme weather. The breathable HDPE fabric can be rinsed and spot-cleaned, and keeping the sail free of standing water and heavy snow will extend its usable life.

• Spot-clean with mild soap and water; rinse thoroughly
• Inspect D-rings and seams periodically for wear
• Take down the sail for storms, heavy snow, or prolonged high winds
• Store dry and folded when not in use for long periods
