Short answer

The expected service life of a modular container house is typically 15 to 25 years for the structural frame when steel is properly treated, with panel and fitting life varying by specification. Galvanized or coated steel frames and durable panels can extend service life, while coastal and humid environments require enhanced corrosion protection and regular maintenance.
