Complete Buying Guide: How to Choose a New 10-Foot Container (First Trip)

Why choose a new 10-foot container rather than another format?

The 10-foot container, also called a 3-meter container, is the smallest standard format in the maritime fleet. Its external length of about 2.99 m allows it to fit where a 20-foot (6.06 m) would not: narrow yard, urban site, back of garden, technical platform. A new "first trip" container has never carried goods: it has only made the journey from the factory to the delivery location. It therefore has an undeformed structure, intact paint and door seals in perfect condition, which is rarely the case on the second-hand market.

This compact format is particularly sought after for three reasons:

• Reduced footprint: about 7.3 m² on the ground, compared with 14.8 m² for a 20-foot.
• Simplified handling: a medium-capacity forklift or an auxiliary crane is enough, with no exceptional convoy in most cases.
• Controlled purchase cost: from €2,850 excl. VAT for a new model, with a lifespan potentially exceeding 20 years outdoors.

Before committing, however, you must check that this internal volume of about 15.9 m³ really matches your needs. A 10-foot container stores the equivalent of 4 to 5 European pallets on the floor, or more when stacking on shelves. For storing large volumes, a 20-foot will be more appropriate. For a technical room, a site office or a secure shelter, the 10-foot is often the best compromise.

Technical criteria to check before purchase

Material and manufacturing

A quality new container is made of Corten steel (or weathering steel). This low-alloy steel contains copper, chromium, nickel and phosphorus, giving it corrosion resistance far superior to ordinary steel. The walls, roof and floor are assembled by continuous welding, ensuring rigidity and water and air tightness. Check that the welds are regular, without porosity or excessive spatter.

The floor must be 28 mm thick marine plywood. This dense, moisture-treated material supports heavy loads and frequent traffic. On delivery, check that it is dry, without damp spots, deformation or musty smell. A floor that "sounds hollow" underfoot may indicate delamination.

Dimensions and usable volume

The external dimensions of a 10-foot container are generally 2.99 m long, 2.44 m wide and 2.59 m high. The usable internal dimensions are about 2.83 m long, 2.35 m wide and 2.39 m high, giving an internal volume of about 15.9 m³. These values may vary slightly depending on the manufacturer. Ask for the exact technical data sheet of the model offered, because some 10-foot containers are actually rebadged 8-foot or 12-foot units.

The maximum payload is around 10,000 kg, but the limits shown on the CSC plate (Convention for Safe Containers) fixed to the door must be respected. This plate summarises the maximum gross weight, payload and tare weight, as well as the date of the last inspection. For a new container, this information is up to date and guarantees compliance with international safety rules.

Doors, locks and Lockbox

The rear doors are double doors fitted with standard container locks, with vertical locking bars and handles. Check that the door seals are flexible, without cracks or crushing, and that the locks work without excessive play. A factory Lockbox is integrated: this is a metal box welded to the door that protects the padlock against cutting or break-in attempts. Make sure it is properly welded and does not hinder closing.

Certification and CSC plate

A new container must have a recent and compliant CSC plate. ISO certification is also a mark of quality. Ask for the documentation supplied with the container (certificate of conformity, technical data sheet) to guarantee its traceability. Without a valid CSC plate, the container may be refused for maritime transport and its compliance with safety rules is not established.

New "first trip" or used: the real comparison

The new first-trip container has never been used to transport goods. It has only made the journey from the manufacturing factory to the delivery location. It therefore has an undeformed structure, intact paint and door seals in perfect condition. This condition is appreciated for uses where aesthetics and watertightness matter, such as fitting out a site office or a technical room.

The used container, on the other hand, has already made one or more trips. Its condition varies: scratches, dents, surface rust, hardened seals, marked floor. Its price is lower, but it may require repairs and offer less watertightness. For non-critical outdoor use (storing building materials, tools), used may be enough. For interior fitting, a workroom or use where appearance matters, new is preferable.

The extra cost of new is justified by:

• A longer lifespan (no pre-existing corrosion).
• Perfect watertightness (new seals, sound welds).
• A neat appearance (intact paint, no dents).
• Complete traceability (certificate, recent CSC plate).

Which use for which need?

Construction sites and building professionals

On a construction site, the 10-foot container can serve as a site office, a storage room for tools and materials, or a changing room for teams. Its compactness allows it to be positioned in a narrow yard or on a small platform, without encroaching on traffic areas. It can be fitted with shelves, a workbench and lighting to become a mobile workshop. The factory Lockbox protects the padlock and complicates theft attempts, which is valuable on an exposed site.

Individuals: garden, workshop, studio

For an individual, it is a robust storage solution for the garden: lawnmower, garden furniture, bicycles, tools, DIY equipment. It can also be fitted out as a workshop, a DIY room or a small extra room, subject to complying with local planning rules. As part of a modular housing project, the 10-foot container can be combined with other modules to create a larger ensemble, or used alone as a garden studio, after insulation and interior fitting.

Agriculture and local authorities

In agriculture, it can store seeds, fertilisers, small equipment or plant protection products, provided safety and ventilation rules are respected. For local authorities, it offers a storage solution for municipal equipment, seasonal decorations or archives.

Retail and events

In retail and events, it can be fitted out as a stand, a ticket office or temporary storage. Its relative mobility (it can be moved with suitable machinery) allows it to be reused on several sites.

Transport, delivery and installation: what to anticipate

Transporting this container is made easier by its size. It can be loaded onto a container truck equipped with a hydraulic arm or a flatbed with an auxiliary crane. Delivery requires suitable access and stabilised ground to set the container down without risk of sinking. It is recommended to allow sufficient manoeuvring space for the truck and to check for overhead lines or obstacles.

A 3 m container can be transported on a truck without exceeding the maximum authorised width of 2.55 m, which avoids exceptional convoy procedures in most cases. The total weight of the vehicle and container must remain within the driver's licence limits and traffic restrictions. For lifting, the use of an auxiliary crane or a suitable forklift is necessary; slings must be attached to the designated lifting corners, in accordance with safety rules. During handling, it is forbidden to pass under a suspended load.

Once positioned, the container must be shimmed on blocks or beams to avoid direct contact with the ground, which limits corrosion from moisture and allows better ventilation under the floor. If the ground is sloping, appropriate shimming must be put in place. Regarding insurance, it is advisable to check that transport and installation are covered by a suitable policy.

Regulations and planning: points to check

In France, installing a container on private land may be subject to planning rules. A container placed on the ground without foundations is generally considered a light structure, but its nature and duration of installation may require a prior declaration of works, or even a building permit depending on the surface area and intended use. It is prudent to check with the town hall's planning department before any installation, especially if the container is to be fitted out as habitable space or an office.

For professional use, installation must comply with the safety and accessibility rules applicable to workplaces. Regarding transport, the 10-foot container can be transported on a truck without exceeding regulatory size limits, which simplifies procedures compared with a 40-foot container. The total laden weight must comply with the Highway Code, and the carrier must hold the necessary authorisations for exceptional convoys if the size requires it.

Maintenance: extending the life of your container

Maintaining a new 10-foot container outdoors relies on a few simple principles. The factory-applied finish protects the Corten steel; however, scratches or impacts can expose the metal to corrosion. It is therefore advisable to quickly touch up scuffs with suitable paint, matching the original colour. Door seals are wearing parts: they should be checked at least once a year, cleaned and possibly replaced if they harden or crack. Hinges and locking mechanisms should be greased regularly to prevent jamming.

The marine plywood floor must be kept dry; if water infiltrates, identify the source (defective seal, hole, condensation) and remedy it quickly. Natural ventilation can be provided by opening the doors for a few minutes in dry weather, or by installing ventilation grilles if the container is used for prolonged storage. Finally, it is recommended to check the stability of the shims and remove leaves or debris accumulated on the roof, which retain moisture.

Comparing the 10-foot with other formats

To choose a 10-foot container well, it is useful to compare it with other common formats. The 20-foot container offers a length of about 6.06 m and an internal volume of about 33 m³, double that of the 10-foot. It remains manoeuvrable and is the most widespread format for professional storage and maritime transport. The 40-foot container, with its 12.03 m length and about 67 m³ internal volume, suits large volumes but requires wider access and more land. The 40-foot High Cube adds about 30 cm of internal height, which is valuable for fitting out as an office or technical room.

The 10-foot container stands out for its ability to be installed in tight spaces, to be moved with lighter lifting equipment and to limit ground footprint. In return, its internal volume is more restricted, making it more suited to selective storage or small fit-outs than to storing large volumes. The choice therefore depends on the nature of the need: for an urban site with little space, the 10-foot is often preferred; for a warehouse or farm, the 20 or 40-foot will be more suitable.

The different types of containers and their uses

Besides format, there are several types of containers for specific uses. The dry, or standard, container is the most common model, fully enclosed, suitable for storing dry goods and for fitting out. The reefer container is equipped with a refrigeration unit and insulated walls, intended for transporting perishable goods or temperature-sensitive products; it requires a power supply and specific maintenance. The open top container has a removable or opening roof, allowing tall objects to be loaded from above, such as machines or bulky parts. The flat rack container, without side walls or roof, is designed for transporting heavy or bulky loads that cannot be loaded through the doors. The high cube container is distinguished by its greater height, useful for interior fit-outs. Finally, the new first-trip container is one that has not yet been used to transport goods, while the used container has already made one or more trips and is in variable condition. The new 10-foot container offered here belongs to the dry category, in a compact and recent format.

Security: what a container really protects

The new 10-foot container has security advantages. The factory Lockbox protects the padlock, which complicates theft attempts. The Corten steel walls are difficult to drill or cut without heavy tools. Doors fitted with standard locks offer proven mechanical resistance. To enhance security, it is possible to add a quality padlock, or even an additional locking system. The absence of windows limits entry points. These characteristics make it a safer storage space than a traditional garden shed. It should be remembered, however, that no container is completely tamper-proof, and surveillance or an alarm system can complement protection.

Final checklist before ordering

1. Check the CSC plate and its validity date: a new container must have a recent plate.
2. Check the condition of the door seals: they must be flexible and crack-free.
3. Make sure the Lockbox is properly welded and that the locks work without excessive play.
4. Examine the floor: it must be dry, without damp spots or deformation.
5. Ask for the documentation supplied with the container (certificate of conformity, technical data sheet) to guarantee its traceability.
6. Check the exact dimensions and payload on the technical data sheet, not just in the listing.
7. Anticipate delivery: truck access, manoeuvring space, stabilised ground, no overhead obstacles.
8. Check planning rules if the container is to be fitted out or remain in place long term.

The price of a new 10-foot container is higher than that of a used container, due to its recent manufacture and impeccable condition. This extra cost is justified for uses requiring a neat appearance, perfect watertightness or maximum lifespan. For any questions about availability, delivery or fitting options, it is recommended to contact the sales team directly, who can provide details on the exact characteristics of the model offered and the delivery arrangements.
