The Container Safety Convention (CSC) is the internationally adopted health and safety criteria to ensure the safety of all those involved in handling containers. Valid CSC plates are required for any shipping container used for ocean voyage transport.

Should I buy a new or used shipping container?

Deciding between a new and used shipping container depends on your budget and the purpose of the storage container. A refurbished shipping container will cost significantly less, but new containers are the best solution for pop-up shops, extra storage for valuable goods, or home modification. 

What are shipping containers made of?

A 20ft container is manufactured from high-quality corten steel, which is corrosion resistant and designed to withstand sea conditions. In addition, high-quality rubber seals ensure the storage container is wind and watertight to protect cargo. The internal flooring is generally made of hardwood.

Do you buy back containers?

Yes! However, to provide an accurate quote for a buy-back, we also factor in transportation costs and how long we will need to store the container before re-sale. We may also decline a buy-back if the unit is in an inaccessible location.
