HOT-DIP GALVANIZING is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal.  While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.  This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.

The HOT-DIP GALVANIZING process has been used since 1742, providing long-lasting, maintenance-free corrosion protection at a reasonable cost for decades. Although HOT-DIP GALVANIZING HAS been utilized to protect steel for generations, the galvanizing process continues to evolve with new technologies and creative chemistries.  The three main steps in the hot-dip galvanizing process are surface preparation, galvanizing, and post-treatment.

HOT-DIP GALVANIZING is an excellent barrier coating for other top-coats such as paint and powder, particularly on items that have areas that are hard to access but will be exposed to atmospheric conditions.  We often specify HOT-DIP GALVANIZING on Boat trailers and architectural fencing before powder coating or painting over the top to provide further protection and a more aesthetically pleasing finish.

We do not have a HOT-DIP GALVANISING facility in-house however we do only use the most trusted suppliers who conform to our Quality System requirements and expectations. We only take on HOT-DIP GALVANISING projects that we can add value to in terms of pre or post the HOT-DIP GALVANISING process.
