We Sell and Install Three Types Of Storm Shelters in Del City
• High-Density Polyethylene Storm Shelters
High-Density Polyethylene (HDPE) Shelters provide rust proof, waterproof, durable, long-lasting storm shelters ─ resistant to environmental stress and mechanical damage. With a 50-year guarantee, HDPE is an engineered polymer…a polyethylene thermoplastic made with a mold. High-Density Polyethylene is also commonly used for: boat lifts and personal watercraft docks, plastic bottles, jugs, food containers, storage bags, underground piping and culverts, plastic lumber and decking, cutting boards, auto parts, toys, etc.. It’s the ultimate in Corrosion Protection.
• Hot Dip Galvanized Storm Shelters
Our Hot Dip Galvanized storm shelters are made of 10 gauge sheet metal and leak tested ─ providing protection from rust and corrosion for a long-lasting, maintenance free storm shelter. With a 50 year guarantee Hot Dip Galvanizing is the process of dipping fabricated steel into a kettle or vat containing molten zinc. While the steel is in the kettle, the iron from the steel metallurgically reacts with the molten zinc to form a tightly-bonded metal coating that offers superior corrosion protection to steel. Using zinc to protect steel from corrosion (hot-dip galvanizing) is a 150-year-old practice! Our Galvanized FlatSafe storm shelter is made of 10 gauge sheet metal. All welds are leak-tested to guarantee they won’t allow ground water to seep into the shelter. Following the shelter is fabricated, the device is Hot-Dip Galvanized to protect your investment for an expected 50+ years.
• Coal Tar Epoxy Storm Shelters
Coal Tar Epoxy is a heavy duty, high build protective coating which has high strength, is resistant to many corrosive reagents, and is excellent at sealing out moisture. It’s commonly used in marine and industrial environments. It’s largely applied to steel to protect it from rust and corrosion. It is frequently seen on steel vessel hulls, underground water and petroleum tanks and pipelines, offshore oil rigs, and dam gates. Our Coal Tar Epoxy underground storm shelter is made of 10 gauge sheet metal. All welds are leak-tested to ensure they won’t allow ground water to seep into the shelter. After the shelter is fabricated, we apply a thick coating of Coal Tar Epoxy into the exterior of the shelter. The Coal Tar Epoxy bonds to the steel and serves to protect the outside of the steel shelter from corrosion and rust. The interior of the storm shelter is painted with red oxide primer paint to protect the steel on the interior from rust and corrosion.

The single-piece lid is larger than the framework of the saferoom opening and sits over the framework, not down inside the frame. Our lid system is a lot stronger than the typical 2-piece lid system provided by everyone else and provides more than adequate ventilation to the occupants.
