Polaris Container House-Details determine quality. We are committed to manufacturing high-end container houses since 2008.
Instant Space Expansion Solution
Our container expansion boxes provide an immediate 30-50% increase in usable space without permanent construction. Designed for seamless attachment to standard shipping containers, these modular units are perfect for growing businesses needing extra storage, pop-up retail spaces, or temporary worksites.
The bolt-on system requires no welding or special tools - just simple assembly that can be completed in hours. Made from high-grade steel with reinforced corners, our extensions maintain the same durability and security as your main container while offering flexible, cost-effective space solutions.
