Raw Material Storage
Steel coil, panels and fit-out materials stored and tracked by batch.
Stage 01From structural steel to finished, packed units — SunModu controls every stage of production in our own manufacturing plant.
From structural steel frames to insulated panel systems, we carefully select materials and control every stage of production to deliver reliable, efficient and cost-effective modular building solutions.
Steel frames in hot-dip galvanized square tube; insulated panels in EPS, rock wool or PU cores; surface and pattern options across 38 UV board colors and 110+ steel panel patterns; flooring and door-window systems configured per project.
Raw material storage through to welded frames — the inputs that decide unit longevity.
Explore the key stages of our modular building manufacturing process.

Steel coil, panels and fit-out materials stored and tracked by batch.
Stage 01
Frames are cut, jig-welded and assembled to dimensional tolerance.
Stage 02
Electrostatic powder coat, oven-cured for a durable exterior finish.
Stage 03
Panels, interiors, MEP and pods are installed on the assembly line.
Stage 04
Every unit is inspected before packing; display yard holds reference units.
Stage 05Incoming material checks, in-process dimensional control and finished-unit inspection precede every shipment. Waterproofing and structural test procedures are applied per product line.
Detailed test documentation is available on request with your quotation.
