Why does the shade sail have curved edges ?

 

How to explain these curves ?

 

The shade sail has naturally curved edges in order to be correctly tightened. The curve makes putting under tension easier. In fact the curves give flexibility for the tension axes.

 

Otherwise, the maladjusted shade sail would create an unattractive pouch (and harmful in the case of a waterproof sail).

 

In addition to avoiding creases on the sail, it gives a design and dynamic aspect to your installation.

 

How is the curve calculated ?

 

The curves differ depending on the shade sail shape. Triangular sails have a curve of 3% whereas trapezoid, rectangular, square, and diamond sails have a curve of 6%.
