Rotomolding Testimonials

See what customers in various industries are saying about a rotomolding leader, Granger Plastics Company!

“We are pleased to advise that the new PolyCone produced by Granger Plastics Company is performing well in the field: Better impact resistance, better scuff resistance and lower cost. When a PolyCone is dented in the field, we just push it back into its original shape and send our enclosed car hauling equipment back on the road. Damage to fiberglass has always required bodywork to repair. We are pleased with the results of our material conversion project with GPC (Granger Plastics Company). ”

Director of Maintenance

“ During the deadly Alabama tornadoes on April 27, 2011, we suffered some damage but considered ourselves blessed. Following that experience, the decision was evident that we would purchase a tornado shelter, in hopes of never having to use it but knowing there was a strong possibility this could happen again. I immediately began searching the internet looking for options available. Deciding on an in-ground shelter, we traveled to several cities in North Alabama to look at the actual units. Our decision to purchase the Granger ISS was a "no-brainer". The Granger ISS was by far the best unit we found. As compared to other in-ground shelters, the Granger ISS deserves a "five-star-rating". The door feature is very impressive and far exceeds any other on the market with regard to structure, safety and durability. Overall the unit provides easy entry/access, is incredibly durable, easily installed and very affordable. It provides peace of mind which carries no price tag. The people at Granger were exceptional to work with and fulfilled every promise they made.
