The elips4sun shade sail offers an exceptionally beautiful form of shading and rain protection. What makes the C4sun shade sails so visually unique is their automatic 3D-dome system. As the shade sail is unfurled, the sail arches upwards. And when it is retracted, the fabric is pulled flat against the winding shaft. This is made possible by arch-shaped, preformed, pre-tensioned strips made from glass-reinforced plastic (GRP). These permanently elastic strips are enclosed parallel within the sail fabric in a ribbed pattern. This innovative construction has made it possible, for the first time ever, to roll an arch-shaped, firmly taut fabric onto a winding shaft. It also allows for a relatively wide range of sail designs, including the almost elliptical form of the elips4sun. C4sun is currently offering three different tensioning masts made from brushed stainless steel for the elips4sun. Built into the masts, the high-precision tensioning mechanism uses 4mm steel cables (V4A) and control weights. This mechanical system of tensioning ensures optimal wind-pressure reduction and minimal maintenance. The impressive und unusual design of the elips4sun furling shade sail not only gives it the appearance of an artistic object but also guarantees a wind-resistant, optimal positioning of the fabric and offers highly effective protection from sun and rain.
