Where to Buy Container Houses

You can purchase container houses through online B2B platforms, local building material markets, or physical integrated housing companies.

I. Online B2B Platforms

1. Industrial product platforms like 1688 and HC.com: You can filter by region (e.g., Zaozhuang) to view enterprise certification logos. Prioritize suppliers with a long-standing membership in the integrity pass program and detailed product descriptions (e.g., material, size, price). For example, companies like Hangzhou Suge Construction Technology Co., Ltd. and Suzhou Hengxiangda Integrated Housing Co., Ltd. offer various specifications of container houses, support customization, and indicate delivery cycles.
2. Alibaba.com: For foreign trade or high-end customization, you can refer to keywords such as 'Custom Prefabricated Container House' and select suppliers that provide material guarantees and factory inspection reports, such as Guangzhou Yuze Integrated Housing Co., Ltd.'s 20-foot prefabricated houses.

II. Local Physical Channels

1. Visiting building material markets: Go directly to large local building material distribution centers (e.g., Yicheng District and Xuecheng District in Zaozhuang) and consult stall owners to obtain the contact information of container house suppliers they have cooperated with for many years. You can view samples on-site and verify qualifications.
2. Integrated housing companies: There are physical yards in cities like Beijing, Tianjin, Hangzhou, and Chongqing that offer standardized products such as construction site dormitories and temporary offices. For example, in Beijing, you need to pay attention to temporary building planning permits and prioritize choosing finished and modified integrated containers with Class A fire protection and thermal insulation.

III. Second-hand Container House Channels

1. B2B wholesale/manufacturer platforms: Obtain second-hand sources through online consultations or Zhihu columns, etc. You need to focus on inspecting the goods:
   • Structure: The four corner columns should have no bending or rust penetration, and the bottom should have no water accumulation or rust corrosion.
   • Roof/wall: The corrugated sheets should have no rust holes, and inspect on a rainy day to confirm no water leakage.
   • Thermal insulation: The rock wool should not be damp or agglomerated. For living in northern regions, Class A fire protection is required.
2. Staking out local construction sites: Contact the project manager 1-2 weeks before the completion of an ongoing project. However, you need to bear the transportation and hoisting costs yourself. The condition varies greatly, so it is generally not recommended.

IV. Key Considerations

1. Price and configuration: The unit price of a brand-new container house should not be lower than 800 yuan per square meter. Be wary of second-hand refurbished or false advertising for low prices.
2. Contract and after-sales service: Clarify the warranty period (usually 1 year), after-sales response time, and whether transportation and installation costs are included in the quotation.
3. Compliance: Temporary buildings need to obtain planning permits and are prohibited from being used as permanent residences.
