Severe weather is notoriously unpredictable. We have a vast knowledge about the conditions and suroundings that cause it and how often this occurs throughout the country. We have sophisticated warning systems, as well as extensive radio and 24/7 news and television coverage of these storms and Tornadoes as they approach and even destroy. Even with all of this technology and warning systems, still hundreds are killed each year from tornadoes, freak storms and other disasters, with thousands more injured. Property loss and damage is routinely in the billons of dollars. Help protect your family today with an investment into your families lives by keeping them safe from tornadoes and tornado destruction with an Inground Shelter by Granger Plastics!
Granger ISS / Tornado Shelter
The extremely durable, innovative, polymer construction of the Inground Safety Shelter can provide a useful life span that under most conditions should exceed 500 years! Unlike concrete, steel and fiberglass Tornado and Storm Shelters, the Polyethylene 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 Safety 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.
The only Storm Shelter with a Safe Room/Panic Room quality door!
See the NEW Granger ISS door exceed both FEMA 320 & FEMA 361 testing!
See the new generation of Granger ISS Storm 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 Storm 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 Storm 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 Storm 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 storm shelter available for single family consumers. Granger Plastics has been manufacturing Storm Shelters for over 15 years currently. Even gaining international attention as early as 10 years ago from Internationally recognized publications such as Plastics News, USA Today and a number of news channels and media outlets across the country!

Rotomolding Company Continues Growth Converting Fiberglass Products to Polyethylene
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.
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.
