This matching local case shows a completed three-floor modular complex with repeatable rooms, covered access galleries, internal stairs and a central project entrance.
The example demonstrates layout potential rather than a fixed standard model. Building footprint, room count, façades, stairs and services are customized for each site.
We have 2 production bases covering approximately 120,000 square meters. Production can coordinate galvanized-steel frames, wall and roof systems, interior finishing and project-specific module preparation.
Drawings, room schedules, finish selections and inspection requirements are confirmed before bulk production.
