The best remedy for the humdrum of life: lots of light, fresh air and inspiration.


»Nowadays, individuality is the greatest luxury.«

Few products illustrate this better than the shade sails from C4sun. The elegant trapez4sun shade sails have an eye-catching design that outshines all conventional systems. The trapez4sun system was designed to suit your unique tastes and dynamic personality. The sail has a distinctively tapered shape that creates an attractive contrast to minimalist architecture or the strictly symmetrical designs of surrounding structures.

Turning style into an experience. In any weather.

The trapezoidal sail is a real head turner – and is also the first choice for unusually shaped terraces requiring an effective and visually appealing sun-shading solution. The system furls and unfurls fully automatically, and the unique atmosphere of comfort and well-being under the arched sail turns every second spent outdoors into a magical moment – in any weather. Rainwater runs off the sides quickly and reliably. With its perfect balance of flexibility and stability, the system masterfully with- stands even strong gusts of wind. As one of the most innovative products on the market, the trapez4sun – like all other C4sun systems – can be easily integrated into modern »smart home« solutions.

Attractive shapes inspire – and open up new perspectives.

Instead of following the trends, C4sun prefers to set new standards. With innovative ideas and exceptional solutions like the trapez4sun – an inspiring shade sail that opens new horizons with its design. Ideal for anyone who wants the time they spend outdoors to be filled with unique moments.

Standard Colours

Every C4sun shade sail is handcrafted to the desired for- mat and size. In addition to the four standard colours, a further 16 colour options are available, enabling you to customise the sail design to fit ideally to the surround- ings and your personal tastes. The colours shown on the left are only intended as a guide. Before selecting a col- our, please contact us to request a set of fabric samples.

For its sails, C4sun uses exclusively WeatherMax 80, a high-strength fabric that is both breathable and extremely watertight. With a fabric weight of 270 g/m2, it combines high tear strength with an optimal elastic recovery and excellent colour brilliance and fastness. WeatherMax 80 is resistant to mould and mildew and offers maximum protection from glare and UV rays.

Mast installation


All options for mounting our shade sails.


Krinner ground screw

With ground screws, the masts can be anchored to the ground quickly, cleanly and securely. This patented foundation system from the German company Krinner is an excellent alternative to concrete foundations. The ground screws are driven into the ground quickly and easily using special equipment. The conical shape compacts the soil around the screw, producing the required stability. There- fore, no time-consuming excavation work is necessary. In comparison to concrete foundations, this method is extremely fast, environmentally friendly and clean.

C4sun Cube

The ideal solution for terraces, particularly roof terraces: Our cubes measure 80 x 80 x 40 cm and can be placed anywhere on flat surfaces. For safety purposes, they are either weighted with up to 400 kg of ballast material or anchored to the ground. The choice is yours: as a place to sit or a decorative planter – our impressively multifunctional cubes are so much more than simply stable bases for masts.

C4sun Flange Plate

Our base flange plates are the best choice if you plan to place your mast systems on an existing foundation or a level surface. This solution is ideal for the installation of a shade-sail system on existing terraces.

C4sun Wall Bracket

Wall brackets are used for mounting mast systems parallel, cleanly and securely to an existing wall. This mounting system guarantees maximum freedom of movement – the shaded area can be used freely, with no obstacles.
