The Celina Tent PROspan Series is a semi-permanent, frame-supported fabric structure. Best suited for long term installations, the PROspan and requires less maintenance than a standard frame tent. Even though it's recommended for long term installations, the installation process is simple enough to allow each structure to be disassembled and reinstalled for short term installations. The PROspan structures have a Keder Track system that makes it easy to slide the roof and side panels out when severe weather or snow is anticipated, reducing fabric wear and decreasing wind load. The PROspan provides an alternative structure that has more flexibility than a permanent building.
