Feature icon tickFront and rear vents reduce moisture in the container.

Normally ISO shipping containers are manufactured with vents located on the container side walls.

The problem with this is that if you intend to place the storage containers directly next to each other, to save space, the vents which allow airflow to reduce moisture are blocked.

Because we have our storage containers manufactured with vents located at each end of the box it means you can maximise your site space whilst still providing your customers with vital ventilation.

Feature icon tickNew builds – PU coated floor (varnish) means spillages can be more easily wiped away.

Liquid spillages by customers can be hard to clean if your storage container has an un-treated plywood floor, making the container potentially unattractive to future users.

Our storage containers are treated with a PU coating which means you can more easily clean up spilled liquids so that your container stays looking its best.

Feature icon tickWaist height locking bars make opening and closing the doors easier.

Containers manufactured for shipping use usually feature locking bars at the base of the doors, this is so that the container can be opened whilst on the back of a truck.

However, your storage containers will likely be located at ground level which would make opening and closing the doors more strenuous for you and your customers.

By manufacturing our containers with waist high locking gear it means users can open and close the doors with much more ease.

And because we also offer bespoke conversion options, such as fitting personnel doors, you can have your storage containers exactly the way you and your customers want them.

Feature icon tickFull 120 micron paint system helps protect against corrosion.

Corten steel containers are applied with marine grade paint but applying too little of this paint can cause premature corrosion.

This not only impacts the appearance of your storage containers to would be customers but can also result in a shorter lifespan of the box.

Don’t worry though, our premium 120 micron paint specification for new build containers helps fight off corrosion.

Feature icon tickLockbox to help protect against attempts of theft.

Each new build storage container we supply comes already fitted with a lockbox which helps to shield your customer’s padlock from forced entry.
