Tensed Shade Sail is called the solar protection system manufactured with a technical fabric, perimeter cable, plates and / or anchoring masts and tension elements that through geometric shapes and curves of tension on their sides cover and protect from the sun a certain surface. They can be superimposed over each other in order to protect a larger surface from the sun.
Velas Alicante is a benchmark in the solar protection sector. Our manufacturing and installation procedure allows us to track the customer’s needs from the moment they decide to install a taut sail.
At first the decision to install a sunscreen as a tense sahde sail is motivated by the differentiation of the product with respect to other systems in the market, once that first motivation is overcome, the client will appreciate the whole an elegant article with lines adapted to its space and totally unique that fits perfectly with the environment.
The design of the tense shade sail is the result of a study of the client’s solar protection needs and the space required for their subsequent enjoyment.
Getting that study balanced is not an easy task.
You have to calculate the sun’s travel in both summer and winter with special emphasis on the highest position of the sun to obtain the projection of the sun protection offered by the taut sail and make it match the optimum possible shade space.
Calculating the possible impact of the wind in the area and place of the installation of the taut sail is also a detail to consider. The wind resistance capacity of a taut sail is superior to that of a traditional awning or pergola, however they are not an element that must be neglected and not pay attention, in case of storm or strong winds these systems must be collected. There is the possibility of carrying out a detailed study of the wind resistance, the possibilities and historical wind in the place and the anchoring necessary for the taut sail to be a fixed structure without the need for collection, this study is carried out in places of public access and civil work.
Another calculation to be made is the thickness and height of the masts or poles that will support the tension of the taut sail as well as the anchoring of these to the ground and / or walls, if this calculation is not carried out correctly the wind resistance of the taut sail will be reduced. If the tensed shade sail are anchored with plates to the wall, the stability of the same should be checked, since the surface in contact with the wall of the plates obtained from the calculation of shade sail tensions.
Finally, it is necessary to calculate the deformation of the tissue that will be produced when subjecting it to the stresses of each anchoring place. It is necessary to compensate this deformation so that the taut sail obtains the greatest possible rigidity. Normally they can be compensated with different heights of the masts and with stress calculations in the warp and fabric weft.
In the models of manual and motorized shade sails, these calculations are multiplied since the variables of collection and extension of the taut sail must be added.
All these calculations, tensioning and installation systems that come with the taut sails are continuously audited by our ISO 9001 quality system that systematically sets the production and quality controls both in the external products that make up the taut sail and the manufacturing processes and installation.
This type of actions are the differentiating elements that make Velas Alicante a reference in quality and design.
