The only Tornado 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 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. 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!

Rotational Molding Company Continues Growth Converting Fiberglass Products!

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 Shelter

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 is routinely in the billons of dollars.

Fiberglass Tornado Shelters vs Polyetheylene Tornado Shelters

The original YouTube video that started the debate! As numerous low-end Fiberglass shelter manufacturers "heard thru the grapevine" that Granger Plastics was out of the gate educating potential consumers as to the differences between Fiberglass and Polyethylene. Many chose to accept the facts and new innovations as Polyethylene as a superior material to fiberglass, while a scarce few who seem to be stuck in the past, refuse to accept that Fiberglass is an inferior material in comparison to polyethylene in terms of Tornado Shelters. Watch the video above to see how the Polyetheylene Tornado Shelter sample excels in comparison against fiberglass! Coming soon, Granger Plastics will be releasing a 2nd Generation Tornado Shelter comparison video, this time it will provide a "handicap" advantage to the less capable Fiberglass material, while also utilizing samples from "known Fiberglass Tornado Shelters" thanks to a number of newly added Tornado Shelter dealers to the Granger ISS Tornado Shelter network! Will the Fiberglass still fail? How will the Fiberglass hold up in comparison against common lawn & garden chemicals? Coming soon!

The extremely durable polymer (LLDPE) construction of the Inground Tornado Shelter can provide a useful life span that under most conditions should exceed 1,000 years! Unlike concrete and fiberglass, the Polyethylene construction won't deteriorate, alleviating concerns 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 Tornado 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 Granger Plastics Tornado Shelter is the only Tornado Shelter your family will ever need to purchase, period.
