Hardware/Tools — Corrosion & Coating: Salt Spray + Adhesion
8 min Read
TL;DR
- Define coating type + thickness + salt spray hours.
- Adhesion test is critical.
Coating failures appear after shipping and create expensive refunds. A rusty tool is garbage.
Why This Matters
Suppliers skimp on plating thickness or pre-treatment. Salt spray testing reveals longevity.
What to ask suppliers
- Q1What coating process is used and thickness target?
- Q2Any salt spray test results?
- Q3How do you verify adhesion?
Red Flags
- No coating specs
- “Same as photo” response
- No test evidence
