What is the service life of Shanghe Prefab Houses, and how is structural quality and durability ensured?

Under normal use and regular maintenance, Shanghe Prefab Houses are designed for a service life of approximately 15–25 years. The steel structural frame undergoes hot-dip galvanization treatment, providing strong and durable corrosion resistance suited to coastal and high-rainfall environments. Shanghe Prefab Houses feature robust sealing and waterproof design as standard, with a wind resistance rating of approximately 120 km/h upgradeable to 150 km/h and a seismic resistance rating of Grade 8 upgradeable to Grade 9.

On quality control, Shanghe conducts rigorous pre-shipment inspections covering raw materials, structural components, waterproof sealing integrity, and electrical systems before any unit leaves the factory. Third-party pre-shipment inspections by SGS, TÜV, or other recognized bodies can also be arranged at the client’s request. To request Shanghe’s material specifications, structural test reports, or quality assurance documentation, contact the technical team.
