What is a Conex Box?

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. In New York, contractors, farmers, and homeowners 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.

For practical buying purposes the three terms describe the same thing across New York: a corrugated steel container, 20 or 40 feet long, with cargo doors on one end, designed to keep wind and water out for decades.

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

New York customers typically choose from three sizes:

  • 20-foot standard. Length 20 ft, width 8 ft, height 8 ft 6 in. Roughly 1,170 cubic feet of interior space, about the same as a two-car garage. Fits most residential driveways. The most popular size in our network.
  • 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. We can source them on request.

Common Uses by Industry

Demand in New York is anchored by Construction, remodeling and the trades. The most common container buyer in every single region of this state, from a Brooklyn gut renovation to a barn conversion in Otsego County. A dry, lockable box on a job site through a New York winter is the reason most contractors call in the first place, and in the five boroughs and on Long Island it doubles as the only secure space on a lot with no room for a trailer., Semiconductors and advanced manufacturing. Micron began site work on its complex at Clay in Onondaga County in 2026 with the first fab planned to come online around 2030 and buildout running into the 2040s, GlobalFoundries runs its fab at Malta in Saratoga County, and there is a silicon carbide fab at Marcy in Oneida County. A build cycle that long is container hungry at every phase, and it pulls in the trades, the laydown yards and the suppliers around it., Apples, and the packing houses and cold storage behind them. New York is consistently one of the top apple states in the country, with the orchard belt running along the Ontario lake plain through Wayne, Orleans and Niagara counties, up the Champlain Valley around Peru and Chazy, and down the Hudson through Ulster and Columbia counties. Harvest runs September into November and bin yards, packing lines and crews all need storage that locks and stays dry., Dairy, and the equipment and feed operations around it. New York is one of the largest milk producing states in the country, and the barns are spread across St. Lawrence, Jefferson, Lewis, Wyoming, Cayuga, Chenango and Delaware counties. Farm shops store parts, feed additives and seasonal equipment on the farm, because town can be twenty five miles away., Wine, cider, beer and spirits. The Finger Lakes wine trails on Seneca, Cayuga and Keuka, the Lake Erie Concord grape belt through Chautauqua County, the North Fork wineries on Long Island, and a farm brewery and farm distillery scene that runs the length of the state. Barrels, bottling supplies, tanks, trellis hardware and harvest equipment all need dry lockable space at properties that have no spare building., Maple, timber and forest products. New York is one of the two largest maple syrup producing states, with sugarbushes across the Adirondacks, the Tug Hill and the Southern Tier, alongside logging, sawmills and the paper mills at Ticonderoga and up the St. Lawrence. Containers end up at landings, sugarhouses and equipment yards a long way from pavement., Salt, aggregate and mining. American Rock Salt at Mount Morris in Livingston County is the largest producing salt mine in the country and supplies a large share of the road salt New York spreads every winter, and there are quarries, sand and gravel pits and gypsum operations across the western and central counties. Mine and quarry yards run on secure on-site storage., Higher education. The SUNY system spans sixty four campuses, with Cornell, Syracuse, Rochester, RIT, Colgate, Hamilton, Ithaca College, Hobart and William Smith, Clarkson and St. Lawrence alongside it. Facilities departments, athletic programs, theater shops and research groups are steady buyers, and summer is the season they buy in., Marinas, boatyards and the fishing fleet. The Long Island and Montauk fleets, the harbors on Lakes Erie and Ontario, the Thousand Islands, Lake Champlain, Lake George and every Finger Lake. Winter haul-out means gear, shrink wrap, engines, docks and hardware all need somewhere to go, and a container beside the yard is the usual answer., Ski areas, camps and the seasonal tourism economy. Whiteface, Gore, Hunter, Windham, Holiday Valley, Bristol Mountain and Greek Peak, plus the summer camps, campgrounds, outfitters and second-home caretakers of the Adirondacks, the Catskills and the Thousand Islands. These are the classic six-months-on, six-months-off storage jobs., Film, television and event production. New York City is one of the largest production markets in the world and the work spills upstate to locations across the Hudson Valley and the Capital Region. Sets, grip, wardrobe, staging and lighting all live in containers at basecamp, and the same is true of the concert and festival business., Ports, freight and warehousing. The port complex at the mouth of the Hudson is the busiest on the East Coast, and inland there is the Port of Albany with its offshore wind tower work, the Port of Oswego, the Erie Canal corridor and the truck and rail terminals along the I-90 corridor from Buffalo through Syracuse and Utica to Rotterdam and the Capital Region. Distribution yards, drayage operators and 3PL tenants buy containers by the row., alongside residential construction and the storage cycle that lake effect snow and deep winter frost drives.

The uses we see most often:

  • Tool, chemical, and equipment storage at working yards. Steel walls, lockable doors, and on-site placement make a conex the simplest substitute for a built shed, a fenced compound, or a temporary office.
  • Weather-event storage for documents, heirlooms, and inventory. Long-cycle uses where the container becomes part of the operation rather than a temporary fix.
  • 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:

  1. How much space do you need? Photograph what you intend to store. A 20-foot unit holds the contents of a three-bedroom home, the materials for one residential framing job, or two pallets stacked four high. A 40-foot unit doubles that. If your list of contents fits on a single garage floor, a 20-foot is enough.
  2. 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.
  3. Will it move? If the container will sit on a single property for the whole life of its use, buying makes sense. If you are running a project that ends in three to twelve months, renting is usually the better answer. Our rent vs buy guide walks through the crossover math.

How Delivery Works in New York

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. Most deliveries follow the same physical sequence:

  1. Site assessment. When you book, we walk through the access route, the placement spot, and overhead clearance. A 20-foot delivery needs roughly about 70 feet of straight clearance and at least at least 14 feet of overhead room. A 40-foot delivery needs about about 100 feet of straight clearance.
  2. Surface check. Concrete, asphalt, gravel, hard-packed dirt, and grass all work. Soft, waterlogged, or steeply sloped ground may need preparation. We can advise.
  3. Final placement. The driver positions the truck, levels the container, and confirms placement before leaving. Repositioning later is possible but usually requires a second visit.

Delivery timing is honest, not aspirational. Across New York:

  • Buffalo, Erie and Niagara counties and Western New York, served from the Cleveland, Ohio depot 194 road miles west on I-90: typically 1 to 2 weeks.
  • Rochester, Monroe County and the Finger Lakes, served from the same Ohio depot at 259 road miles: typically 2 to 3 weeks.
  • Syracuse, Onondaga County and Central New York, served from the Newark, New Jersey depot 238 road miles to the south: typically 2 to 3 weeks.

Permits and Local Rules

Permit rules depend on the municipality. Rural counties often have no requirement at all for a temporary storage container. Urban codes are stricter, and some HOAs prohibit container placement entirely. Before ordering, check with your local building or planning department, and verify HOA rules if they apply. Our local guide walks through the most common scenarios: container permits in New York.

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, which is why an older contractor in Buffalo or Binghamton will say conex box 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 for decades. 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 cover almost every order in New York. A 20ft is 160 square feet on the ground and fits driveways and tight lots. A 40ft is 320 square feet and gives you one long room. A 40ft high cube is the same footprint with about a foot more interior height, which matters twice over in this state: once if you are racking pallets, and again if you plan to insulate, because a cold climate assembly takes real headroom and you do not get it 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. Plan on roughly a hundred feet of that run for a 40ft and about seventy for a 20ft. Two things stop New York deliveries more often than tight corners. The first is overhead: service drops crossing a driveway between two houses are the norm on the older blocks in Buffalo, Rochester and Syracuse, so look up as well as down. The second is downstate and specific: every parkway in the metropolitan area and on Long Island is closed to commercial vehicles, and some of the stone bridges over them have posted clearances under eight feet, so a delivery routes on the Long Island Expressway, Sunrise Highway, Jericho Turnpike and Route 25A instead. We settle that before dispatch rather than at the bridge.
Containers are supplied and delivered by Container One, and the honest answer for this state is that they come from outside it. There is no container depot inside New York, so the western and Finger Lakes cities are dispatched from Cleveland, Ohio and the central, eastern and downstate runs come out of Newark, New Jersey. That single fact explains the whole New York price ladder. Buffalo is the shortest haul into the state at 194 miles and carries the lowest delivered price, starting at $2,886 for a 20ft Wind and Water Tight container. Rochester is 259 miles from the same depot and prices above it. Syracuse is 238 miles from New Jersey and prices between the two, which is why the ladder does not run west to east the way a map suggests it should.
