Wire mesh plating means electroplating welded or woven wire products: kitchen pull-out baskets, fryer baskets, racks, shelving, grills, fan guards. Chrome and nickel are the usual finishes. It sounds like ordinary plating, and it isn't. Wire work is one of the harder part families to plate consistently, and understanding why will tell you a lot about whether a supplier can actually do it.
Why wire is harder than flat stock
Three things work against you. The geometry is complex, so there is nowhere for current to distribute evenly. Wire diameters are small, which means high current density at every exposed edge. And the surface area per kilogram is enormous compared with a flat stamping, so the bath chemistry works harder for the same throughput.
The practical consequence: on a badly racked basket, the outer edges burn while the middle of the mesh comes out bare. Both defects show up on the same part, and neither is fixable after the fact. The part gets stripped and re-run, which is expensive for us and slow for you.
The process, step by step
- Incoming inspection and racking. We check for burrs, missed welds, and deformation. Then we rack the part. Racking is designed per part family, not per job, and it is the single biggest determinant of whether the deposit is even.
- Pretreatment. Degreasing, then pickling or descaling, then activation. This is where adhesion is won or lost. Oil or oxide trapped in a weld joint will come back later as a blister.
- Plating. The part is the cathode. For decorative chrome on wire, we plate nickel first as an undercoat, then chrome on top. The nickel carries the corrosion protection; the chrome carries the brightness and hardness.
- Post-treatment. Rinsing and passivation to stabilize the surface.
- Inspection. Appearance, coating thickness, and salt spray where the specification calls for it.
What to control, and what to ask a supplier
| Control point | What goes wrong if it isn't controlled |
|---|---|
| Racking and current distribution | Burnt edges, bare centers, inconsistent thickness across one basket |
| Pretreatment thoroughness | Peeling and blistering, usually appearing weeks later at the weld joints |
| Food-contact compliance | Baskets that touch food need to meet FDA or LFGB requirements. Ask for it in writing. |
| Corrosion verification | Without a salt spray number in the spec, "corrosion resistant" means nothing |
Where wire mesh plating shows up
Kitchen hardware (pull-out baskets, spice racks, storage systems), foodservice equipment (fryer baskets, grills), appliance parts (fan guards), and industrial storage (wire bins). If your product is a formed wire assembly with a bright finish, this is the process behind it.
FAQ
Can wire mesh plating meet food-contact standards?
Yes. Baskets and racks that contact food can be plated to US FDA and German LFGB standards.
Can you plate pull-out baskets and fryer baskets?
Yes. These are among our core parts. See wire mesh plating.
How do you prevent peeling and bare spots?
Thorough pretreatment prevents peeling. Racking matched to the geometry prevents bare spots. There is no shortcut for either.
