How high can these 20ft steel stores be stacked?
When placed on flat, level, and solid ground (such as reinforced concrete), our 20ft steel stores feature integrated ISO corner castings capable of supporting up to 3 fully loaded units high using twist-lock connectors.
Do I need specialized crane lifting equipment to offload and stack this store?
Yes. Because of their size and weight (2.2 tonnes empty), these units require offloading via a HIAB crane lorry or specialized site crane. We offer full UK delivery with integrated crane offloading services to position and stack your container precisely where needed.
Are these steel storage units weatherproof and condensation-free?
All units are 100% wind and watertight. They include built-in passive airflow vents that maintain air circulation to suppress moisture accumulation. For storage of moisture-sensitive materials, we also offer anti-condensation ceiling treatments (Absorpole / Grafotherm).
