A Long History of Shelter Manufacturing

Granger Plastics Company is a full service custom rotational molder able to carry a project completely from design to manufacturing and beyond. The company has a lengthy history making storm shelters via its custom manufacturing. This experience began soon after the firm was founded. Through the many years of making shelters Granger has had the ability to recognize some typical concerns customers voiced regarding the design and installation specifics of other tornado shelters. It was this forst hand experience with consumer concerns that led Granger to design and manufacture its own shelter, the Granger ISS, to deal with the typical problems seen with this type of item.

This foundation of manufacturing experience was the inspiration of the initial design of the Granger ISS which resolved several issues seen in the previous decade of manufacturing shelters for other businesses. Branching off into the exclusive style of the Granger ISS has actually allowed the improvements to proceed throughout the development of this item. Unlike the typical storm shelter manufacturer the innovations and improvements to the Granger ISS have continued to be implemented.

Commitment to Continuing Storm Shelter Development

Potential tornado shelter customers voiced concern with installation specifications and requirements of various storm shelters throughout Grangers 20 years history of Tornado shelter production. This problem was the premise for the reversed taper design which allowed for installation without any additional anchoring. The door was developed to be level with the ground rather than partially out of the ground or at an angle which was another repeated request from customers. These two innovations were the initial improvements the Granger ISS tackled yet there would be many more to follow.

From that success Granger continued to establish a more secure, easier and additionally aesthetically pleasing unit. Granger has developed a 3rd generation door, which offers the same durable rotational molding construction as the body of the tornado shelter unit. This door, as the previous generations, was tested at Texas Tech University's Wind Science and Engineering research center to meet or exceed FEMA 320 & FEMA 361 debris impact standards. The present door model comes standard with a dual shock system for the easiest door entrance and exit. The door is also available in customized colors permitting consumers to reduce the appearance of the unit or coordinate with house shades or landscape design ideas. . The three step molded entry with locking handrails was also a consideration in the original design. Granger has also developed the non skid surface area of the entry and includes a led lighting system for increased safety when entering the shelter. Finally the newest development of foam filling the unit not only drastically increases convenience of installation, but also additionally battles condensation. Innovation is an important part of Granger's production philosophy and the advancement of the Granger ISS is an outstanding example of that commitment.
