'When I decided to install refrigerated clean rooms in my food production facility, I took the time to research the various suppliers. I chose to use panels supplied by Structural Panels Inc. based on their high quality construction and their ease of installation and use. The service I received was top level from this family business. I truly appreciated the expert guidance from design through to installation. Almost two years later, the panels are performing perfectly, as expected. I will absolutely use Structural Panels Inc. again for our planned business expansion.'
