Conex Box in Louisiana: A Complete Guide for Louisiana Buyers
Conex box, shipping container, storage container: the words get used interchangeably. What changes from one Louisiana 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 Louisiana, containers can serve these industries:
Port and logistics work around New Orleans and the lower Mississippi: lockable overflow storage near active yards.
Petrochemical and industrial maintenance along the Mississippi River corridor and around Lake Charles: tools, fittings and job materials kept organized near the work.
Agriculture across Acadiana and the delta: seasonal equipment and supplies for sugarcane, rice, soybean, crawfish and livestock operations.
Construction, storm repair and restoration: durable storage near a project without putting tools in an occupied structure.
Offshore, marine and fishing work along the coast: secure storage for gear, maintenance stock and nonperishable supplies between jobs.
Universities, hospitals and public facilities in the state metros: temporary or durable storage for renovation, grounds and facilities teams.
Timber, pulp and paper work in north Louisiana: parts, maintenance stock and equipment kept close to rural yards.
Tourism, festivals and events in New Orleans, Lafayette, Baton Rouge and the coast: a dry place for cases, fixtures and seasonal equipment.
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 Louisiana
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 Louisiana:
New Orleans and Southeast Louisiana
Baton Rouge and the Capital Region
Acadiana and Lafayette
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 Louisiana.
What a Conex Box Costs in Louisiana
Pricing is ZIP-specific, because delivery is part of the price. Louisiana delivered pricing: starting at $2,019 for a 20ft Wind and Water Tight container delivered in New Orleans. Prices as of 2026-09-30.
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
A conex box is a shipping container used for storage or another approved purpose. The right grade depends on the contents, condition and site.
Container One delivers on a tilt-bed truck that slides the container off the back. Plan for 110ft of straight, unobstructed space for a 20ft container and 130ft for a 40ft container, at least 15ft of height to drive, at least 22ft of height along the unloading path and at least 10ft of width.
Ask the local authority. Louisiana review is parcel-specific, and New Orleans, Baton Rouge and Lafayette have different official processes.
Use firm level supports and drainage under the corner castings. Have a professional specify any permanent foundation or anchoring.
It depends on the location, when payment is received, the weather and other factors. Container One's Delivery/Dispatch department contacts you to schedule a date and time after payment and site review.
