Popular Shipping Container Conversion Options
Custom-length Shipping Containers
Need a portable building that fits a specific space? We can trim down a shipping container to meet your size requirements. Contact us if you want an 8 ft container, 14 ft container, or any other non-standard size. Your custom-length shipping container will still be weatherproof, keeping contents safe from wind and rain.
Shipping Containers with Your Logo
Branding a shipping container makes it instantly recognisable from afar, providing a smart promotional opportunity for your business. SEA Containers provides custom painting and logo printing on the exterior walls, ideal for containers converted to offices, pop-up stores, storage spaces, and more.
