Why are shade sails triangular?

How do you keep shade sails from sagging?

If your shade sail starts to sag, you can re-tighten it and bring it taught. One way to do this is by using a wire rope that runs through a pocket sewn in the perimeter of your sail. Simply pull the wire rope on each corner until the shade sail retightens and all sagging is removed.

Without a wire rope around the perimeter, tension applied at each attachment point is not distributed evenly in the sail, creating areas of concentrated stress around the corners. This causes the center to sag and increases the risk of tearing at the corners.

Why are shade sails curved?

The sides of a shade sail are curved to ensure proper tensioning. The amount of the curve (catenary curve) depends on the shape of the shade sail and can be adjusted when ordering a custom shade sail.

Why are sun shades curved?

The curves, also known as gores, allows for proper tensioning so that the shade sail does not move about in the wind. The shade sail should be installed with some slope or incline, at least 1:6, with the slant flowing water away from the building or structure to prevent flooding and pooling water.
