For larger shade areas you need to consider a permanent shade structure. You may want a shade structure such as our SolarMax Shade structure. This structure has four pole and a steel roof structure over-which the shade cloth is tensioned. Frontier shade sails can have four or more attachment points and there is no roof structure, the sail itself is tensioned between the points to create its own roof. This is called a tension membrane structure. Both types of permanent shade have their own advantages and disadvantages.
