With the rapid development of the company, surface treatment has become the bottleneck of the company's development. Traditional technologies such as chrome plating and bluing simply cannot meet the needs of the company's development.

Now we are looking for a new surface treatment method -- chemical plating.

The following is the actual photos after the salt spray test:
