Conex Box in Ohio: A Complete Guide for Ohio Buyers
Conex box, shipping container, storage container: the words get used interchangeably. What changes from one Ohio 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.
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.
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 Ohio, containers can serve these industries:
Manufacturing and parts plants around Toledo, Lima, Dayton, Akron and Canton can keep tooling, packaging and spare parts in a lockable container beside the building.
Warehouse and distribution sites around Columbus and along I-70, I-71 and I-75 can add room for overflow pallets, seasonal stock and returnable packaging.
Corn, soybean and livestock farms across western and northwest Ohio can store seed, parts, fencing and tools out of the weather and close to the field.
Builders and remodelers working in Columbus, Cleveland, Akron and Dayton can keep tools, fixtures and materials on site between phases.
Marinas, campgrounds and seasonal businesses along Lake Erie and the Ohio River can hold docks, gear and inventory through the off-season.
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.
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.
How long will you use it? 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 Ohio
Container One offers Tilt Bed and Customer Assist delivery. With Tilt Bed, the trailer tilts back and the container slides off without help from you. Customer Assist requires an anchor point on your site: a chain connects the container to it, and the container slides onto the ground as the trailer pulls away. Delivery follows this sequence:
Site check. You confirm the access route, the placement spot and the overhead clearance before delivery. 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 contacts you to schedule each delivery. Delivery areas across Ohio:
Columbus, Dayton and central and western Ohio
Cleveland, Akron, Toledo and northern Ohio
Zanesville, Athens, Marietta and southeast Ohio
Permits and Local Rules
Permit requirements depend on city regulations inside city limits and county regulations outside city limits. 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 Ohio.

Frequently Asked Questions About Conex Boxes
Possibly, if you buy new. Container One's FAQ says a new container may come with a choice of color, so ask when you request your quote. With a used container, buyers generally cannot select a specific unit.
As of October 14, 2026, a 20ft Wind and Water Tight container starts at $1,988 delivered in Toledo and $2,200 delivered in Columbus.
A 20ft. Cleveland's portable storage rule limits a container on residential property to 20 feet long, and it needs a permit from the Director of Building and Housing. It may stay up to 30 consecutive days a calendar year, or for the term of a building permit for work on the property.
Yes, if the gravel is compacted, level and drained, with firm support under all four corner castings. Where clay holds water, as on much of northwest Ohio's old lake bed, build the pad up so water runs away from the container.
Container One's FAQ says every container is inspected at the depot and again at delivery. If it does not match the grade you bought, you can refuse delivery, and Container One arranges a replacement or a full refund at no cost to you.
