What shape shade sail is best?

triangular shape
Depending on the design of your place, select a shade wisely. Shade sails are used because of their features that can protect you from the harmful UV rays. But, most of the time, in modern houses, these are used as aesthetic focal point. If it is the case, triangular shape shade sails should be your best bet.

How far apart should posts be for shade sail?

For example, if one side of the shade sail has a length of 120 inches, allow at least 12 inches of space between the corner of the shade sail and the mounting point.

Why are shade sails triangular?

A triangle shaped sail will offer less shade than a square, but it’s more spatially flexible and can fit into smaller areas better. Plus, it has one less fixing point, so you can be a little more imaginative with it.

Do shade sail posts need to be angled?

The length of the posts is determined by the size of the sail/s and the height of attachment. Footing depth is determined by the loads and height of attachment. Posts must be angled away from the direction of the load; Supreme Shades as a minimum offsets our posts by 5 degrees off plumb.

Is a 4×4 post strong enough for a shade sail?

If your posts will actually be 12′ above ground, and they’re not supported with any sort of diagonal bracing, you will want 6x6s (or at least 4x6s). 4x4s will flex and bounce substantially at that height.

Why do shade sail posts need to be angled?

THE IMPORTANCE OF HYPAR All shade sails should have a certain amount of twist or shape in their design. This is done by designing the sail to have alternate high and low corners. Known as a ‘Hypar’, this shape increases tension in the shade, reduces flapping in the wind, and improves overall longevity of the sail.

How do you stop 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.

How do you keep shade sails from sagging?

How much slope should a shade sail have?

Design and Layout: One of the best methods of mounting a shade sail is to have high points diagonally opposite each other. This creates an architectural “hypar”. Setting a minimum slope of 15 degrees is ideal. This slope creates a rise to run ratio of 1 / 3.75.

What can I use for shade sail posts?

It is recommended to use a round steel post with a minimum diameter of 90mm, or a 90x90mm square steel post. Post wall thickness should be a minimum of 3.5mm.

Can a shade sail be flat?

A shade sail must never be flat as the forces to keep it flat are beyond the design and engineering parameters. A shade sail should always have 2 high points for 4 or more cornered shade sails. In some cases, your design may be ok with just 1 high point.

Should a shade sail be tight or loose?

Caution: Do not over tension, tension only by hand, and only tight enough to remove creases. Over tensioning can cause damage to your Shade Sail. Your sail should be firm and tight to reduce windflap. After 30 days, check the tension and re-tighten if required.

Why does my shade sail sag 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.

Can you attach a shade sail to a deck?

Shade Sails can be attached to so many structural options including deck posts and columns, large trees, houses, pergolas, and pavilions. Mount a Sun Sail in place with steel brackets, stainless steel D-rings, and more to control the tension of the fabric shade and keep the SunShade in place during high gusts of wind.
