Doing This Makes The Truss Head Screws Stainless Easy To Fade!

Recently, a customer asked for a truss head screws stainless when ordering, but the surface treatment wanted to make bismuth zinc. When customers say this, we generally advise customers not to do bismuth zinc. Why is this?

Generally, the surface treatment of the screws is to make the screws less likely to rust. But stainless steel itself can already do this. Moreover, the truss head screws stainless is used for the surface treatment of environmentally friendly bismuth zinc, and the effect is not very good. Because the adhesion of stainless steel to zinc is not very strong, even if it is made, it is easy to fall off when it is used, that is, it is white. For example, take a stainless steel large flat head screw with an environmentally friendly zinc-plated surface and apply a little force on the paper. The plating on the surface of the screw is easy to drop, and the mark can be clearly seen on the paper.

If you really want black surface treatment, it is usually anodized with carbon steel plated with environmentally friendly zinc or aluminum or titanium. But some customers don’t really want other materials, just want stainless steel, but want a black surface. Then truss head screws stainless can be considered for electrophoresis, vacuum. However, this price is generally high.
