1. Design and Construction
Modular Structure: Built with a design that allows for adding or removing sections to meet specific size and capacity requirements.
Materials: Typically made from heavy-duty steel (e. G., 6mm to 10mm thick) with an inner lining of military-grade hardwood for added insulation. Weatherproofing: Sealed against moisture, dust, and other environmental factors. Coated with rust-proof, fire-retardant paint.
