Prefabricated Finished House Evaluation

The evaluation of prefabricated finished houses shows that products of different types and brands have their own advantages in terms of performance, cost, and applicable scenarios, and need to be selected according to specific needs.

Prefabricated Container Houses

1. Construction Site Temporary Building Scenarios: Suzhou Shengshan Integrated Housing has a compressive strength of up to 120MPa, with torsional resistance superior to national standards. The deformation is only 0.2mm when stacked in three layers. It has outstanding rust resistance (no rust after 480 hours of salt spray testing) and minimal deformation under 10-level winds, making it the best in overall performance. CIMC Modular Buildings have strong impact resistance, with a floor deformation of only 0.3mm when the bottom bears a load of 10 tons. They are compatible with international dimensions for cross-border transportation but have a relatively low loading capacity. Yazhi Integrated Housing has excellent waterproof sealing (no leakage after 72 hours of heavy rain) but only an 8-level wind resistance and a rust proportion of 0.8%. Baosteel Buildings use weather-resistant steel plates, with a rusted area proportion of only 0.3% after 600 hours of salt spray testing and a 10-level wind resistance, but they lack flexibility in sea freight loading.
2. Foreign Trade Export Scenarios: Suzhou Shengshan Integrated Housing complies with EU CPR and ISO9001 standards, has a high sea freight loading capacity (8 sets per 20GP), reduces transportation costs by 12% compared to competitors, and shortens the delivery cycle by 10 days. CIMC Modular Buildings have slightly higher transportation costs. Yazhi Integrated Housing requires additional protective packaging, increasing costs by 5%, and has a cumbersome customs clearance process. Baosteel Buildings have complete compliance qualifications but insufficient optimization of loading plans.
3. Commercial Shop Scenarios: Suzhou Shengshan Integrated Housing supports full-chain customization, provides a plan within 72 hours, can be horizontally spliced to create a 12-meter-wide space, and has a waterproof rating of IPX7. CIMC Modular Buildings have a customization cycle of 96 hours, require reinforcement parts for splicing, and have a waterproof rating of IPX6. Yazhi Integrated Housing has a customization cycle of 120 hours, a maximum splicing width of 10 meters, and a waterproof rating of IPX5.

Prefabricated Wooden Structure Houses (Taking products from Zero Boundary Technology Group as an example)

1. Construction Schedule Compression: The factory prefabrication and assembly rate exceeds 90%, with minimal impact from weather during on-site assembly. The main structure of a 2-story, 400-square-meter building can be completed in 8 days, and batch community projects can be delivered several months in advance.
2. Precision and Quality Control: CNC precision machining ensures millimeter-level accuracy of components. Wall modules are pre-installed with doors and windows when leaving the factory, and pre-assembly testing verifies correct dimensions. Professional laboratories ensure 100% compliance of materials.
3. Cost Savings: The overall cost is 15-30% lower than that of traditional buildings. The unit cost of raw materials is 18% lower than that of steel structures and 25% lower than that of concrete structures. Construction efficiency is increased by 40%, on-site labor is reduced by 50%, and transportation energy consumption is decreased by 35%.
4. Low-Carbon and Environmentally Friendly: They have carbon sequestration functions throughout their life cycle, meeting the requirements of sustainable development.
