Customize black stainless screws, what finishing methods are available?

There are many kinds of surface treatment methods for black stainless  screws.  Today, I’ll mainly introduce three kinds of methods to you: eco black zinc plating,  electrophoresis black and dacromet black.

The price of stainless steel screw electroplated black zinc is cheap, and the surface is relatively black bright and looks beautiful. However, because the surface adhesion of stainless steel is not very strong, the color of galvanized black zinc stainless steel screw is easy to decline.

Screws after electrophoresis black processing mode, its surface has bright color, even though the unit price is more expensive than environmental protection black zinc. And the salt spray resistant time is longer than black zinc.

The unit price of dacromet black screw is relatively moderate, mainly because of its long salt spray resistance time. Therefore, we generally recommend that customers who not only require salt spray test, but also care about beautiful appearance should adopt this finishing method.

Shi Shi Tong Metal Products Co., Ltd. recommends customized black stainless screws for customers to do electrophoresis treatment, dacromet black treatment, in addition to support vacuum plating, high temperature blackening treatment and other ways. Because they are higher cost-effective.

Customers can choose different treatment methods according to different needs. For specific price difference, please ask for Shi Shi Tong.If you required black stainless screws, please contact us: Annie. li@szsst88.com.
