20ft Tunnel Shipping Containers
Overview
A 20ft tunnel container features double access doors at both ends, making it ideal for businesses that need to manage stock from either side or split the unit for dual purposes.
Compact and easy to position, the 20ft model suits sites where space is tight but access flexibility is key. Built to ISO standards in durable Corten steel, each unit includes lockable doors and watertight seals for secure, weather-resistant storage. Whether you’re storing tools, handling event equipment, or setting up a secure split-use container, having doors at both ends gives you more control over layout and loading.
The 20ft tunnel container is a great fit for short-term events, construction sites, portable office-storage setups, or retail and ticketing applications. It’s also easier to deliver and relocate than a larger unit, ideal for mobile use.
