Even some professional customers with some working experience sometimes admit mistakes. It should be understood that iron bolts are not only several times more expensive than stainless steel rivets, but also have significant differences in quality. Their differences are mainly reflected in the following aspects:

No matter how to carry out metal surface treatment for iron bolts, nickel plating or hot galvanizing, they are not comparable to stainless steel rivets in these aspects!

2. The magnetic properties of iron and stainless steel plates are different. Therefore, the magnetic difference between iron rivets and stainless steel rivets is quite prominent. Therefore, if you take a magnet, you can test the iron bolts and stainless steel rivets.

3. The chroma is different. Although the color of iron is dark, the actual effect will be completely different if bright nickel, white zinc and blue zinc are inlaid. However, hot-dip galvanizing of stainless steel hippocampal rivets will make the iron bolts excessively white. On the contrary, it is very easy to distinguish between the bright nickel plated iron bolts and the stainless steel rivets. Because of their similar colors, the bright nickel plated iron bolts are only slightly brighter, Therefore, we should be more careful in the case of identification.
