The truth is, a $500 luxury bag is worth zero if the lock is rusted when the customer opens the box. For brands shipping to humid cities like London, New York, or Singapore, the air is the enemy. That’s why at DG Buddy, we pushed our 48H Salt Spray Test Standard to the limit.

Why choose 48H Salt Spray Test Standard?

Most “budget” hardware uses a quick, single-layer plate. It looks fine in the showroom, but it dies in the shipping container. Our anti-corrosion hardware is built differently. We use a 5-layer composite structure:

  1. Alkaline Copper
  2. Acid Copper
  3. Semi-bright Nickel
  4. Bright Nickel (The critical shield)
  5. Final Color Coating.
Test ParameterIndustry StandardDG Buddy Delivery Standard
Test TypeNeutral Salt Spray (NSS)Reinforced NSS Testing
Duration8 – 12 HoursVerified 48 Hours+
ProcessSingle/Double Layer5-Layer Composite Plating
Nickel Depth$3\mu m – 5\mu m$$\geq 8\mu m$ (Anti-rust Shield)
MaterialsZinc Alloy / IronZinc Alloy / Stainless Steel

By keeping our nickel layer at $8\mu m$ or thicker, we create a barrier that salt and moisture simply can’t get through. In our lab, our parts show zero corrosion after 48 hours of constant salt mist. No pitting, no peeling, and definitely no fading. This exceeds the ISO 9227 standard by a mile.
