Frequently Asked Questions

 
Can this frame support highly massive internal components like transformers? +

Yes. We can customize the base plate thickness and utilize heavy-duty folded profiles for the uprights to ensure the structure handles extreme static payloads without warping.

What are the tolerances for the mounting holes on the base plate? +

By utilizing advanced 12KW fiber laser cutting and precision CNC punching before the bending process, we maintain strict hole-positioning tolerances within ±0.1mm.

Do you manufacture the exterior panels to attach to this frame? +

Absolutely. While we can supply just the bare structural frame, we are a full-service sheet metal fabricator and can produce the complete enclosure, including side panels, doors, locks, and ventilation louvers.

Are these frames shipped fully welded or flat-packed? +

This depends entirely on your structural requirements and shipping logistics. We can provide fully welded, rigid frameworks, or design modular, bolt-together systems for flat-pack shipping.

What surface finishes do you recommend for this type of structure? +

If the frame is internal, it can be left bare or zinc-plated for grounding purposes. For external or high-humidity environments, we highly recommend an industrial powder coating.
