Shade sails strength

shade sails strength If you already read our previous article (shade sails Sailcloth) you might have read what we said about the strength of the shade sail Sailcloth.
The sail needs to be strong, indeed. It needs to withstand heavy rain, hail and windy situations. Because of these weather vagaries, it is absolutely necessary that a shade sail is flexible, strong and water-repellent. Luckily, a shade sail has all of these features.

However, the support posts (or retaining walls or other possibilities) also need to be able to withstand all of the above, and of course they should not fall over because of the immense pressure that the taut Sailcloth gives to these supporting items.

Strength of the Sailcloth

Here are some of the features of a HDPE shade sail:

Light material, which makes it easy (and quick) to fasten to the poles.
Competely water-repellent and impermeable. Besides that, water won't have the chance to retain on the sail, since shade sails are hung up very tightly.
This material is very flexible. Wind can blow on it with speeds up to 200 km/h!
This material is woven in a certain way, which goes against the unravelling of the sail.

Strength of the retaining posts

As you can read, you have the possibility to choose from steel and timber posts.

All of them are strong and have their own advantages and disadvantages, and of course their own typical look.

If you choose steel posts, we advise you to choose for posts with a diameter of 90 mm. (90x90 cm if you choose for square posts), if you prefer timber posts, choose for a diamter of at least 125 mm. Choosing for these sizes will make sure that your retaining posts are strong enough to hold the sail.

Very important to make the retaining posts durable and strong, is that you embed them in a concrete footing. Read all about this in the section 'installation'.
