Three surface treatment processes

1)electro-galvanized 

Zinc plating is the most common coating for commercial fasteners. Moderate cost, the appearance is relatively good, include  blue zinc-plated, white zinc-plated,color zinc-plated and black zinc-plated, corrosion-resistance performance is moderate

 

2)Nickelage

Mainly used for both anti-corrosion and good conductivity products.

 

3)Dacromet

There is no hydrogen embrittlement problem, and the torque and preload are consistent. This applies to fasteners requiring high corrosion resistance and high strength
