In short: Surface finish is what protects the substrate from corrosion and what determines whether the product still looks acceptable after several years of kitchen use. For our two main product families, we use two main processes: chrome over nickel electroplating on low-carbon steel wire baskets, and pickling and passivation on 304 stainless baskets. Both are mature processes. What matters is whether the factory controls them batch-to-batch — substrate cleanliness, plating thickness, weld passivation. We sample-test salt-spray performance on chrome-plated batches at 48–96 hours per ASTM B117 method.
Chrome over nickel — our plated line
For chrome-plated baskets the sequence is straightforward and has been refined over decades of industry practice:
- Alkaline degrease — removes drawing lubricant from the wire-forming step.
- Acid pickle — activates the substrate surface.
- Nickel underlayer — provides adhesion and a corrosion-resistant base.
- Decorative chrome — adds the reflective surface and additional corrosion resistance.
- Rinse and dry — clean water cascade, hot-air dry.
What we control: bath chemistry, current density, dwell time per stage, and substrate cleanliness coming into the line. What we test: salt-spray on sampled units at 48–96 hours per ASTM B117 method. Honest chrome plating is consistent batch-to-batch; the failure mode of cheap plating is pit corrosion at the chrome–nickel boundary, usually showing up at the weld joints first.
Pickling and passivation — our stainless line
For 304 stainless baskets we do not plate. Stainless has its own corrosion protection in the form of a chromium-oxide layer that forms naturally on the surface. The line process is:
- Alkaline degrease to remove cutting fluids and weld discoloration.
- Pickling bath — chemically removes the chromium-depleted heat-affected zone left by welding.
- Passivation bath — restores and builds the chromium-rich oxide layer.
- DI water rinse to neutralize and dry.
The most important thing here is that the welded joints get the same treatment as the rest of the basket. Welding heat disturbs the passive layer; if a stainless basket is sold without proper post-weld passivation, the weld line becomes the first corrosion site.
Nano-coating as a surface option
For specific SKUs in our catalog we also offer a nano-coating surface finish as an alternative to chrome plating. Nano-coating is a thin protective layer applied on top of the metal substrate. The visible difference is a smoother, slightly less reflective finish than chrome; the practical difference is that the coating tends to wipe cleaner of fingerprints and water marks. Buyers asking us about which to choose: chrome for the brighter classic appearance, nano for the cleaner low-maintenance look. We do not claim nano is universally better than chrome — they are different finishes for different visual and use preferences.
We do not offer PVD or DLC finishes. Those exist in the industry but we do not run those lines, and we would rather tell a buyer we cannot than outsource a finish we cannot stand behind.
Surface finish comparison
| Finish | Where it fits | Salt-spray test we run |
|---|---|---|
| Chrome over nickel | Classic bright finish, entry and mid-tier | 48–96 h sampled per batch |
| Nano-coating | Smoother low-maintenance look, mid-tier | 48–96 h sampled per batch |
| Pickle + passivate (304 stainless) | Mid and upper tier, humid or coastal kitchens | Not required — substrate is the barrier |
| Powder coat | Colorway-driven SKUs, anthracite / black / RAL colors | Visual and adhesion check sampled per batch |
FAQ
Q: How do you verify plating thickness?
A: We hold samples from each batch and check plating thickness with a coating-thickness gauge. The records are kept on file and shared with buyers on request.
Q: Is your chrome plating compliant with EU and California regulations?
A: We use trivalent-chromium chemistry on our chrome line. Hexavalent chromium has been phased out of most decorative kitchen-hardware lines under REACH and Proposition 65.
Q: How long does chrome plating last?
A: In a typical dry kitchen, well past the expected cabinet lifetime. In humid environments it depends on plating thickness and substrate quality; this is where cheap plating falls short and proper plating holds up.
Q: Why is pickling stainless necessary if stainless does not rust?
A: Welding disturbs the oxide layer at the weld zone. Without pickling and passivation, that zone can corrode before the rest of the basket. Passivation restores it.
Q: Chrome or nano — which should I choose?
A: Chrome for the classic bright, mirror-like appearance. Nano for a smoother, slightly matte look that wipes cleaner of water marks and fingerprints. Both are honest finishes; the choice is visual and use-preference, not “better vs worse.”
Q: Do you offer anti-fingerprint coatings?
A: For specific programs where it is part of the buyer’s spec, yes — applied as a topcoat on stainless surfaces. We treat it as a buyer-specified extra rather than a standard feature.
