Rotational Molding Provides Tornado Shelters Quality Advantages

Rotomolding Tornado Shelters provides customers a safe place of refuge in a Tornado or Storm.

Tornado Shelters continue to be in high demand late in the 2014 tornado season. Deadly tornadoes throughout Iowa, Arkansas, Nebraska and more are keeping the storms on the minds of residents in and around tornado prone areas. Tornado Shelter sales are spiking late in the season partially because of continued interest from families who live in areas where shelter manufacturers cannot produce high quality units or do not have the ability to keep up with demand.

Granger Plastics Company, a rotational molding leader has manufactured Tornado Shelters for nearly 20 years. While each season seems to be larger than the previous, this year Granger Plastics continues to have a superior advantage over a number of its competitors. “It is a rare occurrence for us to have a process advantage with rotomolding. Typically we are competing against other plastics processes such as blow molding or injection molding where they can produce thousands of parts extremely fast. In the Tornado Shelter market, the competition for a high quality unit is slim to none. We can produce roughly 50 to 75 units per week, while many of commonly utilized Tornado Shelter manufacturing processes can only manufacture a few units per week at best. ” exclaimed Shawn Cravens, General Manager of Granger Plastics.

Tornadoes are seen year round and in areas that are not considered high risk. Many people do not have a safe place to go in their home and the safest place to be in a tornado is in an underground tornado shelter designed to protect you in high wind speeds. Granger Plastics is an internationally recognized rotational molding leader, also known for producing the Granger ISS Tornado Shelter.

Granger Plastics Company, the manufacturer of the Granger ISS, is seeing an increased demand for production during these late active months as well as seeing dramatically increased sales nationwide. Tornado shelters are an increasingly sought after investment for homeowners around the country. This increase in demand, has led to Granger Plastics to recent production expansions and adding new jobs to its Ohio based manufacturing facility.
