The shade sails perform best under the following scenarios:
One of the essential criteria which needs to be considered for ensuring that there is a good amount of water shedding is the slope at which the fabric has been installed.
While installing the shade sail it has to be pulled taut and if possible, twisted in such a way that one of its axis becomes concave and the other becomes convex.
The shade sails featuring a higher corner and one lower corner provide a more aesthetic appeal and they also give out a structurally dramatic look.
When the fabric is pulled taut and twisted slightly, it gains sufficient curvature and this curvature is very essential for maintaining the stability of the shade sail.
It is very important to make sure that the points of fixtures where the shade sails are installed should be strong to withstand any kind of wind conditions unique to that area. If you are still unsure, you must contact a local engineer for this.
Make sure that the buildings and houses can support the load of the shade sail fixture even during poor weather conditions. When there are heavy winds, the shade sail can strain the existing structures. To verify this a qualified local engineer must be contacted.
Galvanized steel is preferred over the wooden posts as they would be rust free and offer a better solution. Wooden posts can warp and rot over time and this can cause misalignment of the shade sail.
All posts should be embedded in concrete footings. Measure out the centers of the footing positions. Dig the holes to the required size for your posts height. For a 3M size shade sail dig footing holes 400mm square and 800mm deep. For 5M or larger shade sails dig footing holes 400mm square and 1200mm deep.
If installing your shade post into soft ground firstly pour a 100mm depth of concrete and let it set completely. Add a gravel bed, 100mm in depth. Position post and add the required amount of concrete. Position the post at a 5 degree angle, sloping away from the centre of the shade sails position.
