How Does Hot Dip Galvanizing Compare to Standard Zinc Plating?

Updated: Apr 22

Determine which is the right option for you.


Before a bolt gets sold to a customer, it undergoes several manufacturing processes to make it suitable for use. Among the final steps that it goes through is the finishing process, which is either hot dip galvanizing or standard zinc plating. To help familiarize you with each, we’ve created this short guide for you to refer to often. That way, if you have questions about the products you purchase from us, you can answer them yourself without any delay.


To begin, we’ll focus on hot dip galvanizing, how the process is done, and what it does to your bolts.


What is Hot Dip Galvanizing?

Hot dip galvanizing is a finishing process that applies a protective zinc layer of coating to bolts. It is dipped into a bath of molten zinc as a way of increasing the longevity of the product. It’s a cost-effective and easy-to-apply method preferred by manufacturers. As long as the zinc is applied at the right temperature, which is anywhere from 830 to 870 degrees Fahrenheit, it should adhere to the steel without issue. Due to the thickness of the zinc, bolts are tapped oversized.


What is Standard Zinc Plating?

Standard zinc plating offers a thinner coating than hot-dip galvanizing. The process, also known as electroplating, uses an electrical current to apply it. Although it isn’t best for use outdoors, the bolts are brighter and similar in color, making them more attractive to look at. Aesthetically, it may be the ideal option if you’re looking for uniformity in appearance.


Determining Which Option is Best for You

Both processes are highly effective and useful. One provides long-lasting outdoor use. The other adds to the look of a finished item without causing it to look odd or out-of-place. It doesn’t matter if you choose hot dip galvanizing or standard zinc plating for the bolts that you buy because each process has its benefits, as mentioned above.
