Why is my shade sail sagging in the middle?
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.
How do I stop water pooling on my shade sail?
Pools of water on any shade sail will shorten its life and you don’t want pooled water on the sail. You can make sure water runs off the shade sail by installing it at an angle. Another way to make water run off the sail is to use a “hypar” twist. Hypar stands for hyperbolic parabaloid.
Do shade sail posts need to be angled?
