Let’s review 10 of the most popular options for your container project.
Lock boxes
What: Instantly turn a shipping container into secure storage by adding a lock box: a steel housing that is welded or bolted over the door locking bars.
Why: Enhances security by protecting the container padlock from bolt cutters and angle grinders. (Some containers are supplied with lock boxes as standard.)
Passive/active ventilation systems
What: Fixed vents, turbines or powered extractor fans that move air and moisture in and out of the container.
Why: As large metal boxes, heat and condensation can quickly build up within a shipping container, making for a less-than-ideal environment for people and perishable goods. Ventilation systems improve airflow, reduce the build-up of moisture and protect items from mould and corrosion.
Insulation kits
What: Spray foam, panels or exterior cladding designed to maintain a comfortable temperature within the container.
Why: Ideal for working and living space conversions, insulation delivers thermal comfort, reduces noise and enhances the energy efficiency of HVAC systems.
Access ramps
What: Metal ramps – portable or fixed – designed to bridge the gap between ground level and the container floor.
Why: Ramps make it easy to move material handling equipment (forklifts, pallet jacks, trolleys) and wheeled items (bikes, cars, farm machinery) in and out of the container. Choose your ramp based on the loads it will need to handle and how often you’ll use it.
Shelving and racking systems
What: Modular shelving or racking that can be bolted in or installed in a freestanding configuration.
Why: These systems maximise your use of space and make items easier to organise and access, both in storage conversions and for sheds, workshops, offices and tiny homes.
Lighting/electrical fit-outs
What: Electrical connections and lighting, whether powered by the grid or by a solar/battery setup.
Why: Without lighting, containers are completely dark and unusable when the doors are closed. Electrical fit-outs provide that light to enhance the usability and liveability of the space.
Windows
What: Purpose-built container windows installed into cut-out wall sections, often with security bars or shutters.
Why: Windows offer natural light (and potentially ventilation), making containers more usable and comfortable. When fitted correctly they do all this while maintaining the security of the container.
Doors
What: Additional access points (beyond the standard cargo doors), in the form of personnel doors, roller doors or glass installations that stretch the length of the container.
Why: Extra doors provide easier movement into and out of the container, improving day-to-day access and workflow by allowing entry without opening the big doors. They can also enhance the aesthetics.
Flooring upgrades
What: Rubber, timber, concrete, epoxy, vinyl or steel overlays or coatings that are applied over the original container floor (which is made from either plywood or bamboo).
Why: In industrial use cases flooring upgrades protect the marine plywood base, improve safety, and make the container easier to clean and maintain. For residential conversions aesthetics and comfort can be enhanced, particularly through raised and insulated flooring.
External paint and protective coatings
What: Repainting or applying specialised protective coatings to the exterior of the container.
Why:Protective finishes extend the lifespan of the container. Custom colours enhance aesthetics and allow a container to be branded in your business’s colours. The right paint can also help reflect heat.
Make a shipping container your own
With the right combination of shipping container accessories, you can transform a simple metal box into any number of usable spaces, from storage to a place to work or live.
Consider how you want to use your container, and prioritise whichever upgrades will enhance its functionality, usability, longevity, comfort and aesthetics.

Shipping containers travel all around the globe, enduring rough seas and high waves. To prevent cargo from shifting and getting damaged during turbulent conditions, it must be properly positioned and secured inside the container. In this section, we explain how to do it - and why incorrect loading can even pose a risk to the entire ship.
A typical shipping container is "in service" for about 20 years - during each trip around the globe, a standard ISO container can carry around 20 tonnes of cargo. Some types of freight leave residue or odors behind. Learn when cleaning is necessary, what hygiene standards apply, and how to properly clean a used shipping container.
