Beijing Chengdong International Modular Housing Corporation, trading as CDPH, has been designing and building modular housing from Beijing since 2009. We are a project-based manufacturer: standard modules are prefabricated in the factory, bolted together on site, and can be relocated and reused when a site moves on. Every modular housing requirement is quoted individually after engineering review — we set no standard minimum order quantity — and the engineering team responds within one business day with a concept proposal and a budget range. Typical applications include engineering camps, commercial buildings, emergency facilities, education facilities and military sites.
Group structure and overseas delivery
CDPH operates as a group. The Beijing corporation is the headquarters and manufacturing authority; overseas projects are run through CDPH (HAINAN) COMPANY LIMITED, the wholly-owned subsidiary of the Beijing corporation, which handles international contracting directly with project buyers and procurement teams. For all enquiries, our contact page reaches both offices.
Head office: No. 8 Art Museum East Street, Xiaobao Art Park, Songzhuang Town, Beijing, China. Hainan office: Room 1207-1208, 12th Floor, Building 14 Phase 2 of Longfor Haikou Times Tianjie, Jinyu Subdistrict, Longhua District, Haikou City, Hainan Province, China.
Three production bases
Production runs across three bases in Hebei, Xinjiang and Sichuan. The Hebei base lies 48 km from Tianjin Port, which supports consolidated sea freight for export orders. The group is supported by 13 subsidiaries and offices, a team of 500+ people and 100+ engineers, and reports 5,000+ projects implemented in 100+ countries.
Modular housing systems
The core product is a factory-prefabricated steel module, built in single, double, triple or more storeys and laid out in I, U, L or courtyard configurations. The frame is galvanised cold-formed steel (t=3.0 mm, SGH340), with 100 mm glass wool insulation in roof and floor, and electrical circuits pre-fitted in the roof.
| Module parameter | Value |
|---|---|
| Module sizes | 6055×2990×2896 mm (internal 5845×2780×2500 mm); 6055×2435×2896 mm (internal 5845×2225×2520 mm) |
| Roof live load | 1.0 / 0.5 kN/m² |
| Floor live load | 2.0 kN/m² |
| Wind load | 0.6 / 0.5 kN/m² |
| Walls | 75 mm colour-steel sandwich panels; seamless S-type rock wool composite panels |
| Flooring | 1.5 / 1.6 mm rubber-plastic flooring |
Two transport-focused variants are built on the same module system: flat pack (the 6055 mm box packed flat for transport and assembled on site) and detachable bolted modules that can be taken apart and reused.
Engineering team, certifications and references
Our 100+ engineers review each project's layout, loads and site conditions before quoting. The group holds CE certification for modular container houses, prefab houses and light steel villas, ISO 14001 and ISO 45001, product carbon footprint certification, National High-Tech Enterprise status, NATA materials certification for Australia, Intertek fire-resistance certification, CCS factory approval, and Intertek ICC-ES / WH building-material compliance for the US market. Fourteen key welders are qualified to AWS, CWB and CE standards. Certificates available upon request.
Export markets are Eastern Europe, North America, Southeast Asia and Africa. Reference projects, at region level, include a port expansion camp in Cote d'Ivoire; a construction camp for a methanol plant; a camp for a cross-sea bridge project in Croatia; a natural gas project camp in Nigeria; a copper mine camp built for −55 °C conditions; and a living camp for a solar power station in Saudi Arabia whose fire performance was verified by Intertek testing.
How project quoting works
- Send your requirement through the contact page; we do not apply a standard MOQ.
- Our engineering team reviews the project and replies within one business day with a concept proposal and a budget range.
- Each project is quoted individually; programme and delivery are agreed against the engineered scope.
