Some questions Shade Sail

10 Sep 2017

Why is it called a Shade Sail?

The dictionary definition of the word sail among other meanings is "Set or union of cloths or pieces of canvas or strong canvas, which, cut in various ways and stitched, tie to the yards to receive the wind that propels the ship."

Therefore a tensioned shase sail is: A set or union of cloths or pieces of canvas or strong canvas that cut in various ways, sewn and tensioned form a surface of shadow.

What are cloths?

Normally the fabric with which the shade sailis made comes in rolls of a given width and length, the cut of a width by a long one is called cloth therefore a candle can have a certain number of cloths according to the surface of the same.

The joining of these cloths is done by welding or sewing, depending on the fabric used. The correct availability of the cloths give the candle a better distribution of tension allowing it to be as tight as possible.

Why are the sides of the stretched shade sail curved and not straight?

Once the shade sail has been made, it is necessary to determine the curvature of each side of the shade sail, this curvature is never the same since it depends on the heights to which the tensioning elements are placed and the distance from the side, by a regular amount the greater the distance from the side the curvature must be greater.

This curvature is what gives the tensioned sail the tension necessary for its correct functioning, if it had the straight sides it could never be totally tense. This lack of tension can be seen in the pieces of fabric that sell on large surfaces, are only pieces of canvas sewn with a ribbon, if they hang can not tighten the central part creating that image of "rag to the wind."

It is necessary to take into account when designing the candle which is the real surface of shadow since that curvatura subtracts shade. Our commercial team has the help of the engineering department that performs a preliminary design of the surface to calculate the required sail.

What are the tensioning elements?


We call tensor element all that complement that is necessary to exert and maintain the tension in the tensioned sail.

Our stretched sails are made following a rigorous study of the surface to be protected. Once the zone is studied, the sail is configured and the type of tensioning element required is established. This sail may require masts, posts or plates, and not necessarily in this order. These tensioning elements are those that are placed between the posts, masts or plates and the sail taut. By tensing each side we obtain the necessary tension for its stability.

What is the difference between the shade sails of Velas Alicante and the shade sail they sell on the internet?

We start from the basis on which comparative is not possible since they are totally different products and does not lend itself to comparison. It is like trying to compare a bicycle with a car, the two perform the transport function but do not do the same.

The ones that are sold by Internet are standard, that is to say they are not to measure they are of a pre-established measures and is what there is. At Velas Alicante we make a detailed study of the place where the customer wants his tensed sail, we make a sketch and advise on the type of fabric that best suits your needs.

Those that are sold online do not install them, you have to install them, they come with an instruction manual and you should place them where you can. Our company has professional installers trained for years in the installation and with its courses of prevention of occupational risks to the day.
Those that are sold on the internet have no guarantee, if they are broken you should send them and wait for a reply. In Velas Alicante covers the warranty against any manufacturing defect for two years and of course we deliver the guarantee in writing.
