What keeps it from rusting?Answer:
All of our shelters are chemically treated and then our below ground shelters are caulked and then coated with 15 mils of coal tar epoxy. All joints are sealed and the unit is outcome is similar to being dipped in rubber. The interior our our below ground tornado shelters and all of our above ground safe rooms are powdercoated. Powdercoating provides a much more durable, longer-lasting finish than paint and our company is the only known storm shelter manufacturer to invest in this process.
