Generally, CD pattern bolts are exterior components that require a generous and beautiful appearance before choosing. Generally, the material used for CD pattern bolts is SUS304, and some will use SUS316 or SUS410 materials. So why not use carbon steel materials? Let’s first take a look at the characteristics of stainless steel and carbon steel

I believe that many people have black spots on the surface of bolts during salt spray testing. Today, I will analyze the causes and countermeasures: “Our bolts are being plated with blue zinc, white zinc, color zinc, or other electrodeposited coatings.
