Conex Box in Virginia: A Complete Guide for Virginia Buyers
Conex box, shipping container, storage container: the words get used interchangeably. What changes from one Virginia order to the next is the size, the grade and the delivery route.
The word conex (sometimes spelled CONEX) is short for "container express," a term coined by the United States military in the 1950s for a standardized steel shipping container used to move equipment and supplies during the Korean War. The original CONEX boxes were 8.5 feet by 6 feet by 6.8 feet, much smaller than today's intermodal units, but the principle was identical: a stackable, lockable, weatherproof steel box that could move by truck, rail, or ship without unpacking.
By the late 1960s the commercial shipping industry had standardized on 20-foot and 40-foot intermodal containers, the units you see on every cargo ship and rail line today. The military term stuck in everyday speech. Many people still call any large steel storage box a conex, even when the unit is technically an ISO shipping container or a purpose-built storage container.
Whichever name is used, the container is a corrugated steel box, 20 or 40 feet long, with cargo doors on one end.
Conex Box vs Shipping Container vs Storage Container
The vocabulary lines up like this:
Conex box. Originally a military-spec container. In modern use, a colloquial name for any steel shipping container used for storage. Most commonly applied to 20-foot and 40-foot units in residential and contractor settings.
Shipping container. The technical term for an ISO-standard intermodal container. These are the units that cross oceans on cargo ships. They are built to ISO 1496 specifications, which dictate dimensions, lifting points, and structural strength.
Storage container. A general retail and rental term used by ground-storage companies. Often refers to the same intermodal unit, but the phrase also covers purpose-built ground-level containers that have never seen ocean service.
If you are shopping for storage, the difference rarely matters. The same physical unit can be sold as any of the three. What matters more is the size, the condition grade, and the delivery logistics.
Standard Conex Box Sizes
There are three standard sizes:
20-foot standard. Length 20 ft, width 8 ft, height 8 ft 6 in. Interior floor about 19 ft 4 in by 7 ft 9 in, with 7 ft 10 in of height.
40-foot standard. Length 40 ft, width 8 ft, height 8 ft 6 in. Roughly 2,350 cubic feet, double the 20-foot. Best for contractors, farms, and businesses.
40-foot high cube. Length 40 ft, width 8 ft, height 9 ft 6 in. The extra foot of headroom adds about 350 cubic feet of usable space, which matters when you store racked goods or tall equipment.
Specialty sizes (10-foot, 45-foot, refrigerated, double-door, side-opening) exist but are less common.
Common Uses by Industry
In Virginia, containers can serve these industries:
Ports and port trucking. The Port of Virginia moves containers through Norfolk International Terminals, Virginia International Gateway in Portsmouth, Newport News Marine Terminal, the Richmond Marine Terminal on the James and the Virginia Inland Port at Front Royal. The trucking, cargo transfer and warehouse businesses that feed those five terminals can store goods in containers they own on their own ground, rather than paying a shipping line a daily fee to hold its container.
Shipbuilding and ship repair. Newport News Shipbuilding on the Peninsula and Norfolk Naval Shipyard in Portsmouth anchor a base of yards, machine shops, riggers and subcontractors that can keep tooling, rigging and staged parts at the fence line instead of trucking it in each morning.
Military installations and their contractor base. Naval Station Norfolk, Naval Air Station Oceana, Joint Base Langley-Eustis, Marine Corps Base Quantico and the Navy's Dahlgren activity in King George County anchor a contractor base across the state that can store tools, parts and program materials on site.
Data centers. Loudoun County's corridor around Ashburn and Sterling has many data centers, and the electrical, mechanical and fit-out crews building and expanding those halls can store conduit, switchgear parts, cable reels and tooling on site through long builds.
Poultry and livestock. Rockingham County and the surrounding Shenandoah Valley are poultry country, and operations around Broadway, Timberville, Dayton, Bridgewater and Harrisonburg can keep feed, bedding, equipment and biosecurity supplies dry between houses.
Apples and orchard fruit. Frederick County around Winchester is Virginia's orchard belt, and growers can store bins, ladders, sprayers and packing supplies through a season that swings from bloom to harvest and back to nothing.
Wine, cider and craft beverage. The hills around Charlottesville, the northern end of the Valley and Loudoun County have wineries, cideries and breweries that can need barrel, bottle, glass and harvest equipment storage that locks.
Timber and forest products. Pine plantations, chip mills and paper operations across Southside and the southeastern counties can keep containers at landings, gates and equipment yards where a shed would not last.
Row crop, tobacco and peanuts. Flue-cured tobacco, soybeans, corn, cotton and peanuts across Southampton, Sussex, Isle of Wight, Pittsylvania, Halifax and Mecklenburg counties can need seasonal storage that locks and stays dry.
Chesapeake Bay seafood and aquaculture. Crab, oyster and clam operations on the Eastern Shore, the Northern Neck and around Reedville can store cages, floats, cull boards, motors and gear right at the water in a steel box.
Higher education. Virginia Tech, the University of Virginia, James Madison, William and Mary, Old Dominion, Virginia Commonwealth, Radford, Liberty, Washington and Lee and VMI have move-in and move-out seasons on top of facilities, athletics and event storage.
Coal, natural gas and heavy equipment. Buchanan, Dickenson, Wise, Russell and Tazewell counties can keep parts, tooling and consumables stored at yards and haul road gates where the ground is already built for weight.
Residential construction and remodeling. Framers, roofers, electricians and remodelers in Northern Virginia, greater Richmond and Hampton Roads can keep tools and materials secure in a locked steel container on a job site.
Common uses:
Tool, chemical, and equipment storage at working yards. Steel walls, lockable doors, and on-site placement make a conex a practical substitute for a built shed, a fenced compound or a temporary office.
Weather-event storage for documents, heirlooms, and inventory.
Construction jobsite storage on long-cycle builds. Project-driven needs where timing, access, and short-term affordability all matter.
Acreage and farm storage. Permanent storage for the things a garage or barn cannot fit.
How to Choose the Right Conex Box
Three questions narrow the decision quickly:
How much space do you need? List what you intend to store. A 20-foot unit works for household goods during a renovation, materials for a residential framing job, or a few pallets of stock. A 40-foot unit doubles that. Compare the list with the container dimensions before you choose.
How clean does the interior need to be? If you are storing tools, equipment, or boxed goods, a used wind-and-water-tight unit is fine. If the unit will be converted to an office, a workshop, or a clean storage space, a one-trip unit saves the cost of repainting and floor refinishing later.
Will it move? If the container will sit on a single property for the whole life of its use, buying makes sense. For a project that ends in a few months, compare the cost of renting from a rental company with the cost of buying. Our rent vs buy guide walks through the crossover math.
How Delivery Works in Virginia
Conex boxes are delivered on a tilt-bed (sometimes called a roll-off) truck. The driver tilts the bed up, and the container slides off onto your placement site. Delivery follows this sequence:
Site assessment. Container One reviews the access route, the placement spot and the overhead clearance before scheduling. A 20-foot delivery needs 110 feet of straight clearance. The truck needs at least 15 feet of height to drive, at least 22 feet of height along the entire unloading path, and at least 10 feet of width. A 40-foot delivery needs 130 feet of straight clearance.
Surface check. Concrete, asphalt, gravel, hard-packed dirt, and grass all work. Soft, waterlogged, or steeply sloped ground may need preparation.
Final placement. The driver sets the container down on the prepared spot.
Container One's Delivery/Dispatch department schedules each delivery after payment and site review. Delivery areas across Virginia:
Hampton Roads and the Eastern Shore, including Norfolk, Virginia Beach, Chesapeake, Portsmouth, Suffolk, Hampton and Newport News
Greater Richmond and the Tri-Cities, and the Interstate 95 corridor north through Fredericksburg into Northern Virginia
The Shenandoah Valley, Central Virginia and the Southside, and the Roanoke Valley out through Southwest Virginia
Permits and Local Rules
Permit rules depend on the municipality. Before ordering, check with your local building or planning department, and verify HOA rules if they apply. The permit guide for this state covers the questions to ask: container permits in Virginia.
What a Conex Box Costs in Virginia
Pricing is ZIP-specific, because delivery is part of the price. Virginia delivered pricing: starting at $2,147 for a 20ft Wind and Water Tight container delivered in Norfolk. Prices as of 2026-08-06.
If you would rather spread the cost, rent-to-own is available through a third-party partner, My Container Rental.
Frequently Asked Questions About Conex Boxes
Conex is short for Container Express, a United States military term from the 1950s for the reusable steel boxes that moved supplies. The name stuck long after the original program ended, and some people still say it, while the freight industry says intermodal container and the storage industry says storage container. For buying purposes the three words describe the same thing.
For anything you are likely to buy, yes. Both describe a corrugated Corten steel box, 20 or 40 feet long, with cargo doors at one end, built to keep wind and water out. The words that actually change what you receive are the grade and the size, not which of the three names the seller happens to use.
Three sizes are the standard storage options in Virginia. A 20ft is 160 square feet on the ground and fits driveways and tight lots, and it also sits under the 256 square foot statewide building permit exemption. A 40ft is 320 square feet, gives you one long room, and sits above that line. A 40ft high cube is the same footprint with about a foot more interior height, which matters if you are racking pallets or planning to insulate and finish the inside, because insulation takes headroom you do not get back.
A tilt bed truck backs in, raises the bed and slides the container off, so it needs a firm, reasonably level straight run behind the drop point and clear space overhead for the bed to rise. That overhead requirement matters in Virginia, because the alleys behind the Fan and Church Hill in Richmond can carry low utility lines and leaning poles, and Old Town Alexandria and Ghent in Norfolk are narrow with parked cars on both sides. Walk the route from the street to the drop spot and look up as well as down. The exact clearance figures for each size are listed on our sizes page.
Containers are supplied and delivered by Container One, dispatched from the depot at Norfolk. As of 6 August 2026, Richmond, about 96 miles from the depot, and Virginia Beach, about 23, had the same delivered price as Norfolk.
