The only Storm Shelter with a Safe Room/Panic Room quality door!
See the new generation of Granger ISS Tornado Shelter doors under go FEMA 320 & FEMA 361 testing at Texas Tech University's Wind Science & Engineering Research Center. The Granger ISS is an underground Tornado Shelter, so in theory, it only needed to be tested to FEMA 320 standards. Due to the high quality engineering staff at Granger Plastics, the Tornado Shelter door not only meets or exceed FEMA 320 standards, it also meets Above Ground Safe Room criteria by exceeding the FEMA 361 standards. The same door passed (2) tests, being impacted (3) times by a 15 pound 2 x 4 at 67 mph, then seeing an additional (3) impacts, by a 15 pound 2 x 4 at 100 mph. Even though the second test was unnecessary due to the Granger ISS Tornado Shelter being an underground unit, but went forward with the more grueling test anyway to display Granger's commitment to safety, innovation and quality. This is all just another example of why Granger Plastics produces the best tornado shelter available for single family consumers. Granger Plastics has been manufacturing Tornado Shelters for over 15 years currently.

Granger Plastics Company has a long history of researching and converting products to polyethylene. One of the most converted materials is Fiberglass. Inferior molecular structure, issues with rotting and deterioration as well as expensive repairs are only a few of the issues with fiberglass. The superior durability and extremely long life span as well as being practically maintenance free are just a few of the reasons our customers choose to switch to polyethylene. It is easy to see how these same qualities of both fiberglass and polyethylene should be considered when making your tornado shelter investment.
Rotomolding Company Continues Growth Converting Fiberglass Products to Polyethylene
Press release date: August 25, 2011
As times are changing and the corporate world wants to stretch every dollar, Granger Plastics is being sought out to convert fiberglass products into polyethylene. Polyethylene's durability, long life span and superior molecular structure make the transition a logical choice for many original equipment manufacturers and other companies. Granger Plastics has made many of these conversions to the great satisfaction of our customers demonstrating the company motto of "Solutions Beyond Expectations".
"Having introduced the world's first all-polyethylene rear trailer 'cone' as the replacement for 'cones' that have historically been fiberglass, 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 ISS Tornado Shelters
The extremely durable, innovative, polymer construction of the Inground Storm Shelters can provide a useful life span that under most conditions should exceed 500 years! Unlike concrete, steel and fiberglass Storm Shelters, the Polyethylene (Plastics) construction won't deteriorate, alleviating concerns and maintenance issues that apply to other materials. Concrete shelters tend to settle and form cracks throughout the unit. With fiberglass moisture is a problem causing the unit to crack, deteriorate and/or possibly rot. Unlike Steel units, the Inground Storm Shelter will not rust or corrode. The extremely thick 1/2" double wall construction, offers not only the extreme strength of a rotationally molded product, but offers a wall thickness combination that exceeds most single wall units.
