"When It Has To Work"

Buildings & Tension Structures


With over forty years of experience in building greenhouses, both inflatable and framed, Kepner’s latest contribution is this highly versatile, convertible greenhouse which is easily operated by one person.  It provides a protected environment during inclement weather including snow loads or an adjustable open top for a natural environment under favorable conditions.

Astronomy Observatory Dome

Another custom design and fabrication challenge was the 13 cover set for the 21 meter dome covering this 12 meter telescope on Kitt Peak, Arizona for the National Radio Astronomy Observatory.

Kepner Plastics has been the fabricator of choice for over 10 years as supplier of precision panels for these proprietary, high-tech tension structures.  For more information please Contact Us.
