If you’re considering using a shipping container for storage, one of the first questions you might ask is: How safe are my items inside? The good news is, when secured properly, shipping containers offer excellent protection against theft, weather, and pests.

Built Tough from the Ground Up

Shipping containers are made from heavy-duty corten steel, originally designed to endure extreme weather and rough sea conditions. As a result, they are incredibly durable and naturally secure—even before any additional security measures are added.

Lock It Your Way

Every container from SEA Containers NZ can be secured with your own container padlock, giving you complete control over who can access your stored goods.

To maximise protection, we recommend using a high-quality, heavy-duty padlock.

Moreover, using a padlock specifically designed for container security ensures it fits properly and offers robust resistance to tampering.

Extra Protection with a Lockbox

For even greater peace of mind, most of our containers come with a free lockbox already installed.

This added feature can significantly enhance your container’s security.

What is a Lockbox? 

A lockbox is a solid steel cover that fits over the padlock area, preventing access with bolt cutters or crowbars. It’s a simple but highly effective way to deter theft and tampering.

Furthermore, adding a lockbox not only boosts physical protection but also increases your confidence in long-term storage security.
