Storm Shelter innovations continue!
Tornado Shelter Adds Bullet Resistant Panel Option to Door
Press release date: October 31, 2011
The Granger Plastics Company continues to add innovation to the construction of the Granger ISS In-ground Safety Shelter by adding a bullet resistant panel upgrades option to the door. The multi layer polymer door was tested at Texas Tech’s Wind Science & Engineering Research Center Debris Impact Test Facility, to meet or exceed FEMA 320 and FEMA 361 specifications. The Tornado Shelter door, bullet resistant panel upgrade option now being offered, will continue to add to the level of protection offered from this unique multi purpose shelter.
The only Tornado 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. 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
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.

Most durable Tornado Shelter!
Granger ISS
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.
