About HUIYANG

Dongyang Huiyang Integrated Housing Co., Ltd. designs, builds and exports container houses from Dongyang, Zhejiang — with our own steel, panel and fit-out production under one roof.

Who We Are

A prefabricated housing manufacturer in Dongyang, Zhejiang

We sit in the building-materials and export belt of the Yangtze River Delta. That location gives us short runs to Ningbo and Shanghai ports, our own import and export licence, and a local supply chain for steel, sandwich panels and fittings.

We design, build and export container houses — flat-pack modules, expandable houses, two-storey units, portable toilets and space capsules — together with the steel structures, panels and bathroom pods that go inside them. Light steel and composite board keep the units corrosion-resistant, earthquake-resistant and easy to take apart and reuse.

From a 45,000 m² site with more than 150 workers, we ship around 5,500 units a month to Southeast Asia, the Middle East, Europe and Australia, holding CE, ISO 9001 and RoHS certification.

Factory & Production

Nine stages, one roof

Steel tube is cut, welded and painted, panels are foamed and pressed, and the finished module is assembled, tested and packed — all on the same 45,000 m² site. Nothing is subcontracted, so a change to a drawing can be quoted without renegotiating with a supplier.
