✨ HDG vs. Zinc Plating: Which One Stops Rust Longer?
Choosing the right finish is the difference between a project that lasts decades and one that fails in years. Here's the 10-second breakdown:

The "Heavy Armor": Hot-Dip Galvanizing (HDG)
· 40 -50μm (Extra thick protection).
· 5-7years in outdoor environments.
· Metallurgical bond, it won't chip or peel even under impact.
· Best For: Outdoor construction, power grids, and harsh conditions.

The "Sleek Finish": Electro-Galvanizing (Zinc Plating)
· 5 - 15μm (Very thin layer).
· Smooth, bright, and maintains tight tolerances.
· Best for indoor use or short-term rust prevention.

Introducing DNL Jockey Wheel (JK60-GB-NR230Z)
· Ergonomic K**b: Designed for the best operating experience, smooth action, no
fatigue.
· Concise Bracket: Our latest innovation. Simple, yet significantly stronger.
· Tri-corn Rim: Engineered for maximum stability and a smoother roll.

Choose HDG for endurance, choose DNL for a superior operational experience. 🛠️
