Arch Building Testimonial

Homer Cameron

Cameron Lumber Homer
City, PA

“We run a commercial sawmill operation and I bought 4 Curvco arch buildings to use for our by products, the boiler building and equipment storage. We picked up the buildings right at the Factory, and everything went smooth putting them up ourselves. I recommend Curvco Steel buildings, it’s the best decision I made when I built the mill.”
