StormBox: Smarter Storm Protection Built from Reinforced Steel

Our StormBox line is engineered from repurposed steel shipping containers, creating a durable, standalone storm shelter solution that provides protection far beyond what a traditional wood-framed structure can offer.

While StormBox shelters are not designed to be buried underground like reinforced concrete bunkers, they offer a powerful, above-ground layer of defense that makes them an exceptional option for residential storm protection.

Why Shipping Containers Make Excellent Storm Shelters

Originally engineered to transport heavy cargo across oceans and withstand stacking loads of tens of thousands of pounds, they are constructed from corrugated Corten steel, designed to resist extreme force, impact, and harsh environmental conditions.

With proper modifications, that strength translates directly into storm protection.

1. Steel Structural Integrity

Unlike wood-framed houses, which can splinter and collapse under high wind loads, shipping containers are:

• Made of heavy-gauge steel

• Structurally rigid on all four sides, especially with no windows

• Designed to resist twisting and torsion

• Engineered to carry substantial weight

This gives StormBox units a significant advantage during high-wind events compared to conventional residential construction.

2. Impact Resistance

One of the greatest dangers during tornadoes and severe storms is airborne debris. While StormBoxes are not designed for direct tornado hits, they can resist the debris created.

Standard homes are vulnerable to:

• Flying lumber

• Roofing materials

• Tree limbs

• Shattered glass

Steel container walls provide a hardened shell that resists penetration far better than drywall, siding, and wood framing.

Nothing is indestructible, but a StormBox offers a substantially higher level of impact resistance than the average home.

3. Above-Ground Accessibility

Unlike underground bunkers, StormBox units:

• Do not require deep excavation

• Avoid groundwater and drainage concerns

• Are easier to access quickly during emergencies

• Can be placed near a home, shop, or business

This makes them practical for rural properties, job sites, ranches, and residential lots where underground construction may not be feasible.

What StormBox Is and What It Isn’t

StormBox shelters are not designed to be buried like a reinforced concrete bunker. Standard shipping containers are not engineered to withstand lateral soil pressure when fully underground without significant structural modification.

However, as an above-ground storm protection structure, StormBox provides:

• A steel protective shell

• Enhanced impact resistance

• A structurally rigid refuge space

• Optional off-grid utilities

• Protection levels that exceed conventional residential framing

Designed for Real-World Conditions

StormBox units can be configured with:

• Reinforced entry doors

• Internal bracing upgrades

• Anchoring systems

• Food & water storage

• Off-grid capabilities

• Escape hatches & much more

Each unit is designed to provide a secure, self-contained refuge space during:

• Civil unrest

• Severe thunderstorms

• High-wind events

• Hail storms

• Hurricane-force conditions (region dependent)

A Smarter Alternative to Safe Rooms

Traditional interior safe rooms often rely on retrofitting existing framing. StormBox provides a standalone, purpose-built structure with its own steel envelope.

It can be:

• Placed adjacent to a home

• Installed at a job site

• Positioned on rural property

• Used as dual-purpose storage + shelter

Built the MicroBox Way - Like all MicroBox products, StormBox follows a structured tier system:

• Foundation – Practical and protective

• Elevation – Enhanced reinforcement and comfort

• Peak – Premium storm-ready features and luxury finish upgrades

Whether you’re looking for straightforward protection or a fully equipped shelter space, StormBox scales to your needs.

Peace of Mind in Steel Form - Storms are unpredictable. Preparation shouldn’t be.

StormBox offers a strong, practical, above-ground solution that provides protection an average home simply cannot match.
