Hardware/Tools — Corrosion & Coating: Salt Spray + Adhesion

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

  • Q1
    What coating process is used and thickness target?
  • Q2
    Any salt spray test results?
  • Q3
    How do you verify adhesion?

Red Flags

  • No coating specs
  • “Same as photo” response
  • No test evidence

Step-by-Step Verification Checklist

  • 1
    Coating type definition
  • 2
    Coating thickness target + tolerance
  • 3
    Salt spray hours requirement
  • 4
    Adhesion test requirement
  • 5
    Batch traceability
  • 6
    Packaging to prevent abrasion
  • 7
    Pre-ship photo + QC evidence
