Alterra S - by ShadeArt UK

Alterra S  - ShadeArt's newest side post parasol or umbrella is designed for the volume commercial customer. Alterra has a lightweight yet high-strength alloy mast, boom and canopy frame with a satin marine anodised finish. The Alterra mast and boom can also be finished with one of over 30 optional timber colours from our unique new timber look – natural looks and beauty with minimal maintenance. The winch and steel connections are from high-grade stainless steel to extend Alterra's life.

Most commercial side post parasols with a boom from which the canopy hangs are typically more wind stable than those that collapse to the mast. Alterra does both! The optional simple fold boom provides excellent wind stability and is easy to fold for storage when not required. In addition, Alterra S is perfect for between seasons as the canopy frame can be unbolted and stored out of the weather with the mast and boom folded discretely in situ. Thus, minimising canopy damage, wear and especially grime and dirt.

For maximum shade cover on hot or sunny days, Alterra can be ordered with ShadeArt's optional rotation lever lock, so the canopy can be easily rotated as the sun moves throughout the day.
