Racks are a sheet-metal business.
We own the sheet metal.
Raw steel comes in; finished racks go out — laser cutting, CNC punching, CNC bending, welding, five-stage pre-treatment, powder coating, assembly and QC, all under one roof. No trading, no outsourced fabrication.

Questions distributors ask
Frequently asked questions
Are you a factory or a trading company?
We are the factory. Grantec operates its own sheet-metal plant in Cixi, Ningbo — laser cutting, CNC punching and bending, welding, powder coating and assembly are all in-house, running since 2010. You buy factory-direct, not through a trader.
What is your minimum order quantity (MOQ)?
MOQ depends on the product and whether you need customization such as your own colour, label or carton. Tell us the models and volumes you are planning and we will confirm the minimum for your order — mixed-container orders across several series are welcome.
Which markets do you export to?
We supply distributors and integrators in the United States, Germany, France and Australia today, and we are expanding partnerships across the EU and in Turkey. Our racks are built to 19-inch and 10-inch international standards.
Can you produce racks under our own brand (OEM / ODM)?
Yes. We do OEM and ODM: your logo and label, any RAL colour, custom sizes and door styles, and custom cartons. We build to your drawings or adapt a standard series to your specification.
How are racks packed for container shipping?
Most cabinets flat-pack into a small number of packages, which cuts shipping volume sharply versus assembled units — knock-down shipping saves up to 60% on the GS server rack and about two-thirds of the space on the GN network cabinet, so you fit many more racks per container. The welded GWC wall cabinet ships assembled, and any cabinet can ship assembled when you prefer.
What is the difference between a wall-mount and a floor-standing rack?
A wall-mount cabinet (our GWA and GWC) hangs on a wall in 4U–22U for switches, patch panels and edge sites where floor space is tight. A floor-standing rack (our GS server rack and GN network cabinet) sits on the floor in 18U–48U for servers and dense network gear, with far higher load ratings — up to 1500 kg on the GS.
