Manufacturing
Raw steel in. Finished racks out. All in-house.
Grantec is not a trader. Since 2010 we have run our own sheet-metal plant in Cixi, Ningbo — around 100 people, six R&D engineers, and the full chain from laser cutting to powder coating under one roof. That is how quality stays consistent at container volume.

Flat-pack container math
Most cabinets flat-pack into a small number of packages, which slashes shipping volume. Knock-down shipping cuts freight by up to 60% versus an assembled cabinet — so you load far more racks per container.
We size cartons to your order and loading practice. Container quantities depend on your product mix — send us your order and we will prepare a loading plan.
