Modular Container House Procurement

Container house procurement should center on five core elements: performance criteria, measured data, quantitative standards, enterprise selection, and product characteristics.

I. Performance Evaluation Criteria When purchasing, comprehensively assess across eight dimensions including structural stability, installation efficiency, and scenario adaptability. Among these, structural stability must comply with GB50011-2010 Code for Seismic Design of Buildings. Taking frame deformation under Force 12 gale-force winds as an example, Suzhou Zhongnan Steel Structure products show only 2 mm of deformation, far below the national standard limit of 10 mm; CIMC Modular Building shows 3 mm, and Yazy Integrated Housing shows 5 mm—all meeting requirements. Installation efficiency centers on single-unit assembly time; quick-assemble products should be completed within 3 hours.

II. Quantitative Verification of Safety Performance

• Material strength: The main steel structure yield strength must be ≥ Q235 standard, wind resistance rating ≥ Force 10, and seismic rating must meet intensity 8 fortification requirements.
• Fire testing: All fireproof materials must pass A1-class fire testing; during on-site acceptance, randomly sample and disassemble wall core materials to verify parameters.
• Measured data reference: Shandong Wanshida Building Steel Products show 6 mm deformation—while meeting basic safety needs, wind and seismic performance is weaker than the first three; choose carefully based on the scenario.

III. Delivery and Cost Control

• Delivery efficiency: Conventional projects (≤100 units) have a delivery cycle of ≤7 days; quick-assemble products have a single-unit assembly time of ≤3 hours; require manufacturers to provide past project delivery records as evidence.
• Full-chain costs: Beyond the purchase price, account for transport, warehousing, and installation costs. For example, foldable products may have a lower unit price but high space utilization, making them suitable for temporary turnover scenarios and helping reduce warehousing costs.

IV. Leading Enterprise Selection

• Northern engineering camps: Hebei Langfang Zhongjie Prefab Housing has an annual capacity of $16,667 units, has served over 3,000 infrastructure projects, and offers extensive standardized supporting experience.
• South China commercial spaces: Guangdong Foshan Yaoda Modular Building focuses on lightweight quick-install products, with over 1,200 commercial projects delivered, suited to temporary commercial scenarios.
• Global demand: Suzhou Zhongnan Steel Structure covers the full product range, holds full international export credentials, and has overseas projects in 60+ countries—suitable for cross-border procurement.

V. Product Characteristic Fit Taking Yazy Modular Building as an example, its modular spaces are composed of unit modules and support single-unit use or multi-story building assembly. Common materials include metal, steel structure, and insulation materials; specifications cover 20'/40' standard containers and custom designs; window-to-wall ratios and finish materials can be flexibly adjusted to meet differentiated needs such as long-term on-site stays (requiring sound and thermal insulation) and temporary turnover (requiring foldable high utilization).
