The correct tension for a standard shade (~100 – 150lbs / 45 – 68kgs) is when the shade is taut and there are no creases in any direction. When taut, a standard shade should flex as a single piece without rippling or flapping in the wind.
How tight should a shade sail be?
Tensioning your Shade Sail
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.
How much wind can a shade sail handle?
When it comes to wind, most shade sails are fabricated to withstand a minimum of 85 mph, three-second gusts. USA SHADE, for one, engineers its structures up to 150 mph, dependent upon the location of the structure. “You have to design sails to zero-wind pass-through,” Donde explains.
Can a shade sail be loose?
The sail should have no sag or droop and you should pretty much be able to hang off it or even sit on it (do not do this, this is just for description purposes!). Sail tension is key and paramount for safety, longevity and water runoff.
Should shade sails move in wind?
2. Can shade sails be used in windy locations? A good quality shade sail that is correctly installed will be able to withstand high winds. Shade sails are designed to form a tensioned structure; under tension the sail adopts a relatively solid shape and should not flap in the wind.
Do shade sail posts need to be angled?
Ideally, they should be installed at an angle of 10 degrees for steel and 20 degrees for timber posts. The angle should be away from the shade sail, so account for the angle and the length of the turnbuckles when you dig your post holes.
Are shade sails worth it?
When selected with care, shade sails are a great way to block out harmful UV rays while adding style to your space. They come in a variety of colors, shapes and sizes, and are generally constructed of UV-resistant materials. … Shade sails should also be weather resistant, so you can keep them up rain or shine.
Why do shade sails sag?
Wire rope is an essential part of our shade sails. … 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 long do shade sails last?
A shade sail will probably last about eight to 10 years. However, that can increase or decrease dramatically depending on the weather in your area. If the shade is often subject to high winds, it might deteriorate faster.
Are shade sails easy to put up and down?
Generally, shade sails are permanent structures, but if you’d like to take it down at any time of the year, using pulleys is the way to go. Untie the pulley ropes, let the tension out, and detach each pulley from the sail and attachment point. It’s as easy as that! Easy up, easy down, no problem.
