Shade Sails are made of high density polyethylene shade cloth that is especially manufactured with tensioned fabric structures in mind. The knit is made using monofilament and tape filler. The fabric is treated with UV stabilizers to give it long life in direct sunlight. Depending on color, the average shade rating is approximately 90% and the UVR block is approx. 95%.

The perimeter of each sail has a catenary curve designed into it that controls the fabric tension in the center of the sail. Therefore, when tension is placed on the perimeter cable, the fabric will have uniform tension. They do not sag or flap in the wind.

Attachment hardware is all marine grade stainless steel and has locking mechanisms to assure that sails do not detach or come loose accidentally. Generally, one turnbuckle is used per sail, and the remaining corners are attached using "D" or "Twist" shackles of the appropriate size for the expected corner loading.
