Job Site Storage That Locks and Stays.
A steel box that bolt cutters can't open, doors that meet you at ground level, and a box that's yours to keep when the job wraps.
We drop containers on active sites, delivered from a depot in your area. No rental contract, no CDL on your end, no forklift to load it.

Why containers work for contractors
Four reasons a steel box beats a job-site trailer, a cargo van, or a wood toolshed on an active build, and the specifics that back each one up.
Harder to break into than a job site trailer
ISO shipping containers are built from weathering (Cor-Ten) steel, the same corrosion-resistant alloy used for ocean freight that crosses the Pacific stacked nine high. The cargo doors close onto a steel hasp built to take a discus or puck lock, and there's no soft spot to exploit: no gap at the roofline, no plastic skylight, no aluminum skin a battery grinder chews through in seconds.
Compare that to a standard job site trailer: single-skin walls, a residential-grade door lock, windows. For a crew that's lost a generator or a pallet of copper overnight, the difference isn't cosmetic. A container is the closest thing to a vault you can set on dirt.

Container doors swing open at grade. Tools, materials, scaffold sections, and rolling equipment go straight in and out without a lift gate, dock plate, or pallet hand-off. The floor is a plank deck, typically marine-grade plywood, laid over steel cross-members: the same deck the unit hauled freight on. Whether it takes your loaded pallet jack or your forklift is a capacity question, and the only number that answers it is the one in the manufacturer's specification for that unit. Any load near a limit is a question for the manufacturer or a licensed engineer before your crew drives in. We do not issue load ratings.
Interior height is a standard 7'10" and the door opening is roughly 7'8" wide by 7'5" tall, so a standard pallet jack and most walk-behind equipment clear it without a fight.

We deliver from a depot in your area. You call when the site's ready; we drop the box. When the punch list is done, the unit is yours to keep for the next job or resell.
There's no rental center to visit, no trailer to register, no CDL required on your end, and no monthly meter running while the unit sits idle between phases. The container is yours, so there is no rental term to close out when the job ends.
Flexible for multi-trade and phased projects
One 40ft container holds material and tool storage for several trades at once (electrical, plumbing, framing, finish) without anyone tripping over anyone else's gear. When a new phase opens up and you need a second box, we drop another. When an early phase closes out, the first box is still yours for the next phase or the next job.
Availability depends on inventory; we confirm timing when you request a quote, so storage keeps pace with the schedule instead of dictating it.
Weighing a job-site trailer or a gang box?
Most crews get to a container after trying the alternatives: a rented job-site trailer, a gang box in the bed of a truck, or a plywood field shed. Each has its place; none of them is a lockable steel room you own. Here's the honest comparison for securing tools and materials on an active site.
| On a job site | Job-site trailer (rented) | Gang box | Steel container |
|---|---|---|---|
| Security | Single-skin walls, residential-grade lock, windows | Solid for hand tools, but small and pryable at the lid | Cor-Ten steel, lockable door hasp, no soft spot |
| Capacity | Decent, but tapers and wheel wells eat into it | Hand tools and small power tools only | Full crews, materials, and rolling equipment; a 40ft holds several trades |
| Access | Steps or a small ramp up to the door | Lift the lid and bend in | Doors open at grade; walk or forklift straight in |
| Cost model | Rented, with a monthly meter that runs between phases | One-time buy, low cost | Buy once; it's yours when the job wraps |
| Weather | Holds up, but seams and windows can leak | Basic; not fully weather-sealed | Wind & Water Tight: sealed against rain, snow, and pests |
| On & off site | Towed in and out; needs a hitch and a truck | Craned or forklifted into a truck bed | We deliver on your schedule, no CDL on your end |
A trailer earns its keep as a site office, and a gang box is hard to beat for a two-person crew's hand tools. But for locking up materials, power tools, and shared gear across trades (the stuff that walks off overnight), a steel container is the hardest target on the site, and the only one of the three you own outright.
A Container Office Starts as a Steel Shell
Plenty of the container offices you see on job sites started life as a plain used box, and that shell is what we sell: a sealed, lockable Cor-Ten steel room, Wind & Water Tight, delivered to the site. The outfitting is your project. Power, insulation, lighting, windows, a man door, and climate are the buyer's builds, handled by your crew or your electrician; we do not sell modified or turnkey container office units. Two honest cautions. We make no claims about habitability or building-code compliance, and an outfitted container is not automatically an occupiable office. Whether your site can host one is a permits and zoning question, and confirming it with your local authority is the buyer's responsibility. What the shell gives you is the hard part done: a weather-tight steel envelope that locks, sitting exactly where the work is. Crews converting a box to a container office usually favor the 40ft High Cube for the extra foot of headroom; a 20ft fits a foreman's office on a tight site.
The lock matters more than the box
A container only protects what's inside it as well as the hardware on the door. The good news: the right lock is cheap, and the wrong lock is the only real vulnerability. Here's how crews secure a unit on an active site.
- 01Use a puck or discus lock, not a padlock. A puck lock seats inside the door's lockbox recess where there is one, leaving almost no shackle exposed. There's nothing for bolt cutters to bite. A standard padlock with an open shackle is the one thing on the whole box a thief can defeat in seconds.
- 02Add a lockbox shroud if the unit doesn't have one. Many container doors already have a welded lockbox; if yours doesn't, a bolt-on steel shroud covers the lock body entirely.
- 03Lock the right-hand door first. The locking bars on the right door cam behind the left, so securing it last means both doors are pinned shut.
- 04Key multiple units alike on big jobs. Running several containers across a site? We can coordinate matching locks so your super carries one key instead of a ring of them.
A puck lock and thirty seconds of habit turn a steel box into the hardest target on the site, usually enough to send an opportunist to the next jobsite over.
Most crews arrive at this the same way, after the second break-in rather than the first. We wrote that pattern up as a field story: the contractor who stopped losing tools out of his truck, and what changed when the gear started spending the night behind a locked steel door instead.
Photo · Container lock comparison Which container fits your situation
The right size comes down to how many trades share the box and how tight the site is. A single crew on a residential remodel rarely needs more than a 20ft. A commercial build with four trades staging at once almost always wants the 40ft. Here's how contractors typically split it, and our 20ft vs 40ft comparison covers the trade-off in full.
Photo · 20ft vs 40ft containers on site Best for single-trade tool storage, tight urban infill sites, and projects with limited staging room. It is the shortest box we sell, so it fits where a 40ft cannot, though you still need room in front for the doors to swing open, which makes it the go-to for downtown work where you're borrowing the curb lane.
View 20ft container → 40ftBest for multi-trade material storage, full tool sets across crews, and jobs where you want staging and secure storage in one unit. Twice the floor of a 20ft for far less than twice the cost, and the workhorse of any active commercial build.
View 40ft container → 40ft HCBest for tall material loads, racked storage, and jobs that need the extra foot of interior height a standard 40ft doesn't give (about 2,694 cubic feet on the same footprint). Wind & Water Tight (used): weather-tight steel with no holes and doors that seal.
View 40ft High Cube →Most contractors on active builds choose the 40ft Wind & Water Tight unit. It handles the most volume at the best price per square foot of storage.
Where we deliver
We deliver to job sites across the region, including Huntington, Charleston, and Parkersburg, shipped from a depot in your area, and our drivers know the difference between a wide-open subdivision lot and a downtown infill site with a curb lane and a power drop overhead. These are some of the metros we deliver to:
What a jobsite drop actually looks like
Delivery to an active site is routine for us, but it goes smoother when the crew knows what the truck needs. Three things make or break it:
Clear approach
A tilt-bed delivery needs at least 100 feet of straight, clear approach, whichever size you order. The container ends up about 3-5 feet from where the truck stops, so plan the drop spot with the truck's path in mind, not just the final footprint.
Overhead clearance
The tilt-bed lifts high during placement, so you need at least 14 feet of clearance along the whole approach. Low power lines, sign trusses, and tree limbs are the usual culprits on tight sites.
Firm, level ground
The box needs a stable surface that won't let a loaded container settle unevenly. Compacted gravel or packed earth is fine; soft mud and steep grade are the things to flag ahead of time.
Tell us your entry width, surface, and any overhead obstacles when you request a quote, and we'll confirm the site works before anyone schedules a truck. On constrained downtown sites we'll do a site assessment up front rather than send a driver to a dead end.
Photo · Tilt-bed container delivery Common questions
Can a container be delivered directly to an active construction site?
Yes, and it's one of the most common setups we handle. Our delivery truck uses a tilt-bed or boom-off method depending on site conditions. We need enough space to maneuver the truck (at least 100 feet of straight approach for a tilt-bed delivery), a stable surface to set the container on, and overhead clearance of at least 14 feet. For tight urban sites, we do a site assessment upfront. Tell us about the site when you request a quote (entry width, surface type, and any overhead obstacles) and we'll confirm feasibility before scheduling.
What kind of lock works best on a shipping container?
The door hasp on most shipping containers accepts a standard discus or puck lock: Abloy, Medeco, or Master Lock "puck" series. Where the door has a welded lockbox, these seat inside its recess and are virtually impossible to cut without heavy equipment; not every used unit has one, and a bolt-on steel shroud can be added if yours does not. Avoid standard padlocks with exposed shackles; they're vulnerable to bolt cutters. If you need to key multiple containers to the same lock for a large project, let us know and we can coordinate.
How much space does the truck need to deliver a container?
For a tilt-bed delivery, the truck needs at least 100 feet of straight approach and 12 feet of width clearance at the narrowest point, whether you order a 20ft or a 40ft. Overhead clearance should be at least 14 feet along the entire approach path. The container will be placed roughly 3-5 feet from where the truck stops. If the site is tight, describe the layout in your quote request; our drivers are experienced with constrained job sites.
Can you stage containers across the phases of a build?
Yes. Phased delivery is one of the main reasons contractors choose us over a rental yard. We can drop multiple units at once for a large early phase, or stagger drops so storage arrives as new trades mobilize. If you need boxes positioned in a specific configuration (side-by-side with doors aligned for a shared staging run, for example), describe the layout in your quote request and we'll sequence the delivery so the footprint works and every door stays accessible. Tie the schedule to your phase plan and we'll match it.
What happens if we need to move the container mid-project?
We can relocate a container within our service area for a repositioning fee, and once a unit is loaded that is usually the simplest route. If your crew would rather move it with equipment already on site, plan around two things. First, forklift pockets are not a given: many 20ft units have them in the base and 40ft units generally do not, so confirm what your actual unit has instead of planning a mid-project move around pockets a 40ft may not have. Second, the corner castings are the designed handling points, and whether a particular forklift, excavator, or telehandler can take that load is a question for that machine's rated capacity and its operator rather than ours. We do not issue lifting or load ratings, and any lift you are not sure of belongs with the machine's manufacturer or a licensed engineer. Empty weights help you start that conversation: a 20ft runs about 5,000 lbs and a 40ft about 8,000 lbs or more, before anything you put inside it.
Is a shipping container better than a job-site trailer for tool and material storage?
For securing tools and materials, usually yes. A job-site trailer works as a site office, but it's single-skin with a residential-grade lock and windows, while a container is Cor-Ten steel with no soft panel to cut, and many container doors carry a welded lockbox that shields a puck lock; if yours does not, a bolt-on steel shroud can be added. Doors open at grade so you walk or forklift straight in, and a 40ft holds storage for several trades at once. A trailer still wins if you mainly need a place to sit, plan, and run paperwork; the container wins when the priority is keeping gear from walking off overnight.
Gang box or shipping container: which is better for a job site?
It depends on scale. A gang box is unbeatable for one or two crews' hand tools and small power tools: cheap, portable, and lockable. But it fills up fast and offers no room for materials, rolling equipment, or shared gear. A shipping container is the step up: a lockable steel room you can walk into, big enough for a full crew's tools plus materials, and hard enough to break into that it deters the opportunist a gang box can't. Plenty of sites run both: the gang box for daily hand tools, the container for everything bulky and valuable.
Can I get a storage container just for the length of a construction project?
Steel Box Direct does not rent containers. We sell them outright or rent-to-own, and for job sites we deliver when the site is ready. When the punch list is done, the unit is yours to keep for the next job or resell. We can also stage multiple units across phases. Tell us your schedule and delivery zip in the quote request and we'll plan the deliveries around your phase plan.
