Runheng supplies façade contractors, window and door companies, louver specialists and developers with fabricated metal systems under their own brand. You keep the client relationship and the specification; we deliver the fabrication, the documentation and the traceability.
We are not a trading company. Cutting, welding, assembly, finishing and packing take place in our own workshops in Jiangmen, Guangdong.
Louvre systems, aluminium cladding, sunshades and steel supports fabricated to your shop drawings and delivered to site or to your assembly line.
NH-series aluminium windows and doors, complete with hardware, gaskets and packing — a fabrication partner without the factory overhead.
Single-source packages for louvres, balustrades, steelwork and cladding, with one work-order trail from approval to delivery.
