Shipping container offices are a smart and affordable option for businesses that need flexible workspaces. But to make the most of your container, you need to take security seriously. Strong protection helps prevent theft and damage.
Whether your container office is on a building site or used as a permanent space, keeping it secure is key. In this guide, we’ll show you simple, effective ways to improve shipping container security — from choosing the right padlock to securing doors and windows.
Choose a Strong Shipping Container Padlock

One of the easiest ways to improve your shipping container security is by using a proper padlock. Standard locks don’t offer much protection. They can often be cut with tools like bolt cutters. For better protection, choose a shipping container padlock made from hardened steel. These are tough, weather-resistant and hard to break into.
At THS Containers, we offer large padlocks made for this exact purpose. They’re 80mm wide, come with four keys and are built to stand up to bad weather and forced entry.
To boost shipping container security further, fit a lock box. This metal cover goes around the padlock, making it hard for thieves to get tools near the lock. With a quality padlock and lock box combined, your container is much harder to break into.
If you need extra locks for inside your container, we also sell small padlocks. These are 60mm wide and also come with four keys. They’re ideal for securing equipment or storage areas inside your container.
No matter your setup, THS Containers has the right padlocks and accessories to help keep your goods safe.
Secure All Doors and Windows
Don’t forget that doors aren’t the only way into a container. Windows can also be a weak spot. Fitting steel shutters or anti-vandal window locks adds another layer of protection.
If your container has a pedestrian door (like a regular door) or extra side entry, consider installing a multi-point lock. These secure the door at the top, middle and bottom. This not only stops break-ins but also helps the door stay strong in bad weather.
Place Your Container Smartly and Secure the Perimeter
Where you place your container matters. Try to put it in a bright, open area. This makes it harder for intruders to sneak up without being seen. You can also add motion-sensor lights to scare off trespassers.
Using CCTV cameras is another great option. Place your container within view of existing cameras, or set up your own. This makes it easier to monitor activity and acts as a strong deterrent. Then, display signs indicating the presence of CCTV and alarms.
Add fencing or other barriers around your container if possible. It helps stop people from getting close and adds to your overall shipping container security setup.
Maintain Your Setup and Consider Extra Features
Regular checks are important. Look at your padlocks, hinges and seals to make sure they’re not rusting or damaged. Also, test any cameras or alarms to make sure they’re working properly.
If you store valuable items in your container, think about adding more advanced security. For example, you can use motion alarms or remote monitoring systems. These tools let you keep an eye on your container, even when you’re not there.
