Commercial Modular Bolt Together Safe Rooms

Modular Or Bolt Together Commercial Safe Rooms Storm Shelters

This model is an alternative to businesses that want to keep their staff, clients and visitors safe during the threat of tornadoes. Just like their counterparts, the modular shelters are designed to be equally safe, and can withstand EF-5 tornadoes.

Torshel’s modular shelters can be installed in existing buildings in places such: offices, garages, living rooms, waiting rooms, warehouses, etc. They must be on a solid concrete foundation.

You can also use them as safe vaults, we can install digital or regular deadbolts so you can store important items inside. They are not fire proof, you can buy a little fireproof safe box and put it inside the Torshel safe room.

The modular safe rooms can be installed outdoors as long as you can cover them from rain. You can install a carport or something similar.

This particular model consists of steel panels, weighing approximately 50 lbs. each, connected together using structural steel bolts/connectors and attached to a concrete slab foundation with an anchoring system. Such units are equipped with four heavy-duty lock pins that fasten the door to its frame to ensure your safety. To meet the needs of our customers, our modular units typically come in the sizes of 6×8, 6×10, 6×15, 6×20, and 6×40. The panels are 6” or 12 ”. Additional height is available up to 8’ for an additional fee.  The maximum width of a modular safe room is 6’. You can customize the size on increments of 6” or 12”

Among the benefits of installing a modular or bolt together storm shelter, one can mention:

  • No need to excavate
  • Can be installed inside an existing room in your business or school as long as you have a solid foundation
  • Can be fitted to just about any size room.
  • Can be expanded to any size in panels of 6” or 12” increments.
  • It is portable

How To Install it?

There are several options available to the customer:

Order a custom-made unit, and we will bring it to you. If the installation site is within a 500-mile radius from Torshel’s base, our experienced installers can perform the job. Some trips fees may apply. Otherwise, Torshel can hire a contractor at the delivery location to install it for you for an additional fee.

Another alternative is the DIY option, which may be worth considering. Once ordered, we ship the unit to you. Here, the client conducts the installation by himself/herself. Though, Torshel recommends involving two people with some experience in construction projects for the installation of these units. Torshel will provide the client with guidelines, and a video tutorial on how to conduct the process. Among the basic tools needed: a rotary hammer drill, 3/4 inch diameter by 6” or 7” concrete drill bit, 3 lb. hammer drilling, 3/4 inch wrench, and a vacuum cleaner. The installation procedure, depending on the size of the unit, can take between one to two days.

Where Can This Type of Shelter be Installed?

These safe rooms are designed for existing structures or for those that are in the process of being built. They can literally be installed in any room, closet, under the stairs, and or in the garage on a concrete slab with 4” of thickness or more. If you have carpet or hardwood floor, please ask for 6” L anchor bolts. When dealing with new construction or a new addition to your building, these shelters can also be installed after the concrete foundation is cured, and before the framing goes up.

When installing this type of shelter, make sure there is a minimum distance of 3” to 4” from the wall of the house to the shelter’s wall so the bolts can be installed easily. Existing tile must be removed prior the installation of a modular shelter.

This type of shelter can also be installed outdoors bolted down ona concrete foundation.

Modular panels come powder coated from the manufacturer to prevent rust. If installed outdoors, the unit will need protection from the elements (i.e., rain, and sun). In terms of maintenance, due to the exposure to weather elements, Torshel recommends reapplying silicone to the roof of the unit every couple of years. Be advised that deep scratches can compromise the integrity of the paint. If deep scratches are not repainted, water will gather in the surface and corrosion and rusting will occur.

In order to minimize weathering damage to the unit, Torshel recommends installing a carport on top of the unit.
