We match China-based suppliers for residential prefab houses, compare quotations and coordinate evidence against your local design brief.
Four house routes share one rule: the option matrix freezes shell, partitions, finishes and sanitary scope on a dated revision.
These are illustrative inquiry briefs, not completed projects. We request project-specific evidence from shortlisted suppliers before any capability or compliance claim is accepted.

For a coastal inquiry, the buyer's local engineer must establish wind and corrosion criteria. We ask candidate suppliers for calculations, coating specifications and connection drawings. No quoted design speed or permit outcome applies until the project location and authority are known.

Panel thickness alone cannot establish roof capacity or whole-building thermal performance. The supplier should identify the roof build-up, structural load path and tested assembly. A local professional must confirm the snow load and code path.
A shortlisted supplier may present ISO 9001 evidence for its management system; verify certificate holder, scope, validity and issuing body for this inquiry. This is not structural approval.
Ask the shortlisted supplier for any current ISO 14001 document and its scope. This does not establish embodied carbon or project energy compliance.
ISO 45001 addresses occupational health and safety management. It does not set the fire resistance rating of a wall. A 60-minute target, when a project asks for one, has to be tied to the tested assembly, including joints and openings.
A 100k, 1300 sq ft or 2000 sq ft search does not fix the wind, snow or sanitary package. The desk replies with the missing criteria, not with a universal rate.
