A used container often looks rough at first glance. The paint has faded, one panel has a dent, and a few orange spots show near the bottom rail. I want to help you decide which of those marks matter and which ones do not.
I judge a container by what it has to do: keep water out, protect your gear, carry weight, and lock. Every check in this guide ties back to one of those jobs. If you are shopping for a used shipping container for sale, these checks give you a clear way to compare units and choose one you can trust for years.
I also explain why MoCan Containers is a strong place to start your search, and how their yard setup makes these checks easier to carry out.
Cosmetic Wear and Real Damage Are Different Things
Most used containers have spent years outside, so they show it. Faded paint, shallow dents, and light surface rust are normal signs of age. Steel boxes built for hard use carry these marks and keep working.
Real damage affects the structure, the roof, the floor, or the doors. That is where you should spend your attention. When you walk up to a container, sort every flaw into one of two groups: looks bad, or works badly.
Faded Paint
Faded paint comes from sun and weather. It changes the color and removes the shine, but it does not change how the container performs.
Look for these details:
- Chalky, dull color is cosmetic.
- Small chips are easy to touch up.
- Large patches of bare steel need attention, because paint protects the metal from moisture.
Repainting a container is simple, and a fresh coat can improve the look and extend its life. If you plan to paint it anyway, faded paint should not bother you at all.
Dents
Container walls have ridges built into the steel. Shallow dents in those panels are common and do not weaken the unit.
Pay closer attention to these spots:
- Corner posts and corner fittings. Bent or cracked corners can affect stacking and lifting.
- Top and bottom rails. The long edges carry much of the load.
- Door frame. A bent frame can keep the doors from closing flat.
- Sharp creases. A crease with torn or cracked metal is a bigger worry than a smooth, round dent.
A good test is to run your hand over the dent. If the steel feels smooth and the surface is whole, it is a surface mark. If you find a split or a sharp fold, ask more questions.
Rust: Surface or Deep
Rust is the flaw that worries buyers most, and it should get a careful look. The difference between the two kinds is easy to see.
Surface rust is orange and powdery. You can rub it with a wire brush, and the steel under it stays solid. This kind is common and does not affect security or weather protection.
Deep rust looks different. Watch for:
- Flaking layers of metal
- Holes or thin spots
- Soft areas when you press with a screwdriver handle
- Rust along the bottom rails and around the door base, where water collects
If you find holes, walk away from that unit. If you find light surface rust, you can brush it, treat it, and paint over it.
Check the Inside
The outside tells part of the story. The inside tells the rest.
Step in and close the doors from the inside. Let your eyes adjust, then look at the walls, roof, and door edges. Any spot of light that shows through is a spot where water can enter.
Then check these items:
1. Roof. Look for pooled water marks, patches, or sagging.
2. Floor. Press on the boards. Soft spots, stains, or a musty smell point to moisture.
3. Door seals. The rubber gaskets should be whole and flexible.
4. Door hardware. The handles should turn, the locking bars should move, and the doors should swing and close with little effort.
5. Walls. Look for rust that has pushed through from the outside.
A container that passes these five checks will keep your contents dry and secure.
Why Choosing Your Exact Unit Matters
Photos do not show you a dent depth, a floor stain, or a door that sticks. You need to see the container in person, and that is one reason I recommend MoCan Containers.
They are a local, family-owned business with yards in Billings and Bozeman, and they keep the largest inventory of shipping containers within a 300-mile radius. That range gives you real choices to compare. At their yards you can walk up to each unit, inspect it, and pick the one that suits you. The container you choose is the one they deliver to your site.
Each used unit they sell is inspected to confirm it is wind and watertight, lockable, and structurally sound. That gives you a solid starting point, and your own walk-around adds a second layer of confidence.
Here is how to plan a visit:
- Billings: 1721 Old Hardin Rd, Billings, MT 59101. You can stop by the yard to view inventory. Call (406) 661-1226.
- Bozeman: 39 Jays Way, Gallatin Gateway, MT 59730. Call ahead at (406) 661-1684 to schedule a visit.
- Hours: Monday through Thursday, 8:00 to 5:00. Friday through Sunday visits are by appointment.
Pick the Right Size for Your Space
Condition is one part of the decision. Size and placement matter too.
A 20-foot container fits in tighter spots such as a driveway or small yard. Delivery needs about 70 feet of straight, clear space. A 40-foot container gives you twice the length and the most storage in one unit, and delivery needs about 100 feet of straight, clear space plus room for the truck and trailer to turn.
MoCan Containers stocks used units in both sizes at both yards. Their tilt-bed trailers place the container where you want it, and their team reviews your space and access with you before the drop-off. Pricing depends on size, condition, and supply, so call them for a quote and an inventory check.
Consider a Rental or a New Unit
If you need storage for a few months, a rental may fit better than a purchase. MoCan Containers rents 20-foot and 40-foot units starting at $150 and $190 per month, with terms that start at one month and extend as long as you need.
If you want fresh paint and minimal wear, ask about their new one-trip containers. Used units cost less and offer the same steel construction and weather protection, which makes them a smart choice for long-term storage, farm use, job sites, and workshops.
Bring This Short List With You
Keep these steps in your pocket when you visit a yard:
1. Walk around the whole container and note every dent and rust spot.
2. Press on rusty areas to find soft metal.
3. Check the corners and door frame for bends.
4. Close the doors from inside and look for light.
5. Test the floor, seals, and locks.
6. Confirm the delivery space at your site.
Faded paint, shallow dents, and surface rust should not scare you. A sound roof, solid floor, tight doors, and straight frame are what count. Use these checks, choose a seller who lets you see the exact unit, and you will end up with a container that serves you well.
