In-house engineering
Structural drawings, load calcs and stamped reports for your jurisdiction.
We design, fabricate, inspect and ship prefab homes and steel buildings from one site near Weifang — so the engineer who draws your unit is in the same building as the line that builds it.
Quality Prefab House grew out of a steel-structure workshop into a full prefab manufacturer, selling almost entirely to overseas buyers. That shaped how we work: drawings and certificates in your standard, packing built around container economics, and English-speaking engineers who stay reachable through assembly.
We are not a trading company reselling someone else's units. Engineering, steel fabrication, panel assembly, quality control and export documentation all sit under one roof, which is how we keep both the price and the detail under control.
No trading-company markup, no lost detail between vendors. Four disciplines work side by side from first drawing to sealed container.
Structural drawings, load calcs and stamped reports for your jurisdiction.
CNC cutting, robotic welding and hot-dip galvanising lines on site.
Three-stage QC with photo reports before every container seals.
FOB, CIF or DAP — loading plans that maximise units per box.
You see the engineering and the spec sheet before committing, not after.
Every container is documented at QC and at loading, so there are no surprises at the port.
Our engineers stay reachable while your crew builds, with supervision available.
Whether you are a distributor building a catalogue, a contractor on a deadline or a developer planning a camp, you deal with the factory directly — one point of contact, one set of drawings, one accountable team.
