Technical characteristics of the 40ft Dry container

Before considering any use or modification, it is essential to know the dimensions and capacities of this container. The standard 40ft Dry model complies with ISO 668 and ISO 1496-1 standards, which guarantee worldwide compatibility for transport and lifting.

Dimensions and volume

• External length: 12.192 m
• External width: 2.438 m
• External height: 2.591 m (8 ft 6 in)
• Internal length: approx. 12.032 m
• Internal width: approx. 2.352 m
• Internal height: approx. 2.393 m
• Internal volume: approx. 67.7 m³
• Floor area: approx. 28.3 m²

These dimensions are indicative and may vary slightly depending on the manufacturer and year of construction. The 40ft High Cube container, 30 cm taller, is not covered here: the model offered is a standard Dry.

Weight and payload

• Tare weight: generally between 3,600 kg and 4,200 kg
• Maximum payload: approx. 26,000 kg to 28,000 kg
• Max gross weight: 30,480 kg

These values comply with ISO standards and allow very heavy loads to be stored, provided the floor and ground are suitable.

Materials and construction

The container is made of Corten steel, a low-alloy steel that resists atmospheric corrosion thanks to a protective oxide layer that forms on the surface. The side and front walls consist of corrugated sheets welded to vertical posts. The roof is also made of reinforced corrugated sheet. The floor is 28 mm marine plywood, treated to withstand moisture and heavy loads. It is fixed to steel cross members. The rear doors are fitted with four locking bars per leaf (eight in total), with vertical locking bars and rubber seals. The container can be stacked up to nine units high in a maritime configuration, but for ground use it is generally placed on blocks or cross beams to avoid direct contact with the ground and allow ventilation.

Common uses of the used 40ft Dry container

Thanks to its large volume and robustness, the used 40ft Dry container suits many uses. Here are the main areas where it is commonly employed.

Professional storage and logistics

In the logistics and distribution sector, the 40ft Dry container is often used as an extension of storage space, temporary or permanent. Its great length allows a forklift to enter, making loading and unloading easier. It can hold palletised goods, building materials, furniture, industrial equipment, agricultural products, light vehicles or spare parts. In terms of Euro pallets (1.20 m x 0.80 m), around 20 to 25 pallets can be stored on the floor, and up to 40 when stacked two high, subject to available height and floor strength.

Construction sites and civil engineering

On construction sites, the 40ft container serves as a tool store, technical room, changing room or site office after basic fit-out. Its length allows partitions to be installed to separate several spaces (for example, an office and a canteen). It can also serve as a welfare unit for teams.

Agriculture and livestock

In farming, it is used as a storage shed for hay, seeds or equipment, or as shelter for livestock after modification. Winegrowers can store bottles or equipment. Livestock farmers store animal feed. Its resistance to weather and pests makes it a safe shelter for harvests.

Individuals: storage, workshop, garage

For individuals, the 40ft container can become a garden storage space, a DIY workshop, a garage for a car or motorbike, a wine cellar, a games room, or storage for garden equipment. Its size allows a passenger vehicle to be parked inside, provided suitable access is arranged (ramp, additional door).

Events and specific uses

In the events sector, it is used as a technical room, control room or storage space for equipment. In the maritime and port sector, this type of container is used to transport various goods, but also as a workshop or store on the quays.

Possible modifications and fit-outs

The used 40ft Dry container can be converted into many spaces, provided certain rules are followed and the necessary fit-outs are planned. Here are the most common conversions.

Modular housing and tiny house

Converting a container into a dwelling is an ambitious but achievable project. It requires effective thermal and acoustic insulation (inside or outside), suitable ventilation, heating and possibly interior cladding. The raw container is not designed to be habitable as is: openings must be cut for windows and doors, the structure reinforced if necessary, and construction standards met (insulation, fire safety, accessibility). Use as a dwelling generally requires a building permit.

Commercial premises and fixed food truck

A 40ft container can be fitted out as commercial premises, a fixed food truck, a gym, a recording studio, etc. For food use, specific hygiene standards apply (washable surfaces, ventilation, plumbing). The fit-out must be designed for public access, with emergency exits and compliant accessibility.

Site office or technical room

For professional use, the fit-out can be simpler: partitions, electrics, lighting, air conditioning or heating. A 40ft container can be divided into several offices, a meeting room and a storage area. Insulation is important for optimal comfort.

Workshop, garage, studio

A 40ft container can be converted into a DIY workshop, a vehicle garage, an artist's studio, etc. Adding an extra door, an access ramp and a ventilation system is often necessary. For a garage, an opening wide enough for a vehicle to pass through must be provided.

Custom storage

For storage use, the fit-out can be limited to installing shelves, racks, a dehumidification system and lighting. It is important to ventilate the container to prevent condensation.

Points to check when buying a used container

Before buying a used 40ft Dry container, several checks are essential to ensure its quality and compliance.

Structural condition

Check that the corner posts, top and bottom rails, and corner castings are not cracked or deformed. These elements are essential for stability and lifting. Inspect the roof and walls for holes, perforating rust or signs of water ingress. Test the doors: they must open and close without forcing, and the seals must be flexible and properly in place. Check the floor: it must not be soft, rotten or missing boards. If the container has been modified (openings, partitions), make sure this has not compromised its structure.

Watertightness and "cimentier" quality

The container offered is of "cimentier" quality, which corresponds to a robust container, often used in the construction sector, and airtight and watertight. This means it has no water leaks at the roof, walls or doors, and the seals are in good condition. Traces of surface rust, scratches, dents or repair marks may be present, without compromising structural integrity.

CSC plate and certification

Check for the CSC plate (Convention for Safe Containers), which certifies the container's compliance with safety standards and indicates its date of manufacture and maximum weights. This plate must be legible and up to date. If you are buying for maritime use, the container must be certified "cargo worthy"; for land use, a "wind and watertight" container may suffice.

Cleaning and decontamination

A used container may have been used to transport various goods; thorough cleaning is recommended before using it for sensitive storage (food, textiles, etc.). If the container has carried chemicals or dangerous goods, it must be decontaminated according to the appropriate procedures. We do not provide a detailed history of previous cargoes, but we can point you towards professional cleaning solutions.

Care and maintenance

To extend the life of a used shipping container, regular maintenance is necessary. Inspect the roof, walls and floor annually for corrosion, perforation or water ingress. Small areas of rust can be treated with a wire brush and an anti-rust paint suitable for Corten steel. Door seals should be cleaned and possibly replaced if cracked or hardened. Locks and hinges should be lubricated to prevent seizing. The wooden floor can be cleaned with a mild detergent and treated with a water-repellent product to prevent moisture absorption. If the container is used to store moisture-sensitive products, it is advisable to install a dehumidifier or moisture absorbers, as condensation can form inside due to temperature variations. Adequate ventilation is also important to prevent mould. For outdoor use, it is advisable to raise the container on blocks to avoid direct contact with the ground, which limits corrosion from below and allows air circulation. If the container is exposed to sea spray, periodic rinsing with fresh water can help reduce corrosion. Finally, if modifications are made (drilling, welding), care must be taken to protect the exposed areas with suitable paint.

Regulations and transport in France

Transporting a 40ft container in France is subject to heavy goods vehicle regulations. A 40ft container is 12.192 m long, which exceeds the maximum length allowed for a standard articulated vehicle (16.5 m for a tractor + semi-trailer combination). Transporting a 40ft container therefore requires a suitable vehicle (container semi-trailer) and may be subject to traffic restrictions (hours, routes, dimensions). The maximum authorised gross combination weight must not exceed 40 tonnes for a standard road combination, and the container's weight (tare + load) must be taken into account. For lifting, a full 40ft container can weigh up to 30 tonnes; appropriate lifting equipment is therefore required (mobile crane, high-capacity forklift). Transport must be carried out by a qualified professional, with the necessary permits (exceptional convoy if dimensions are exceeded). For installation on private land, local planning rules should be checked: in some municipalities, installing a container may be considered a construction and require a building permit or prior declaration. It is advisable to contact the town hall's planning department. In addition, if the container is intended for habitation, it must comply with construction standards (insulation, fire safety, accessibility). Finally, if the container is imported from a country outside the European Union, customs duties and taxes may apply, as well as health and plant health checks.

Comparison with other container sizes and types

The 40ft Dry container differs from the 20ft by its roughly double capacity (67 m³ versus 33 m³). The 20ft is more manageable, lighter and easier to transport, but offers less space. The 40ft is better suited to storing large volumes and fitting out living or working spaces. The 40ft High Cube (HC) container offers an additional internal height of about 30 cm (2.695 m instead of 2.393 m), which can be an advantage for storing tall goods or fitting an insulated ceiling. The standard 40ft Dry container is more common and generally cheaper than the High Cube. The 40ft Open Top container has an opening (tarpaulin) roof to load out-of-gauge goods from above, but it is less watertight and more expensive. The Flat Rack container has no side walls or roof and is used for heavy or bulky loads. The Reefer container is refrigerated and allows perishable goods to be transported, but it is more expensive and requires a power supply. Finally, the 45ft container is an extension of the 40ft, with an internal length of about 13.556 m, but it is less common and harder to transport. The choice between these different types depends on the intended use, budget and transport and installation constraints.
