The Proper Way to Handle Galvanized Steel

The process of hot-dip galvanizing is done when steel or iron is covered with a layer of zinc. This is done by immersing the metal in a vat of molten zinc. There are several galvanizing plants, each offering an array of services and bath dimensions. In many cases, the galvanizer will also be responsible for the transporting and handling of the fabrication process, both before the galvanizing process and after it.

 Weight of the Metal and Bath Dimensions

The majority of galvanizing plants offer an array of baths in different sizes. It’s crucial that you find a company that has a galvanizing bath with the proper dimensions for the item that is being galvanized. Bolted or welded joints on bigger fabrications must be considered to ensure that they will not exceed the capabilities of the cranes lifting capacity or the dimensions of the bath.

Double Dipping Considerations

Larger fabrications that aren’t able to be completely immersed during a single dip may be rejigged, re-turned, or dipped once again to ensure complete coverage, which is a process that is called double-dipping. The double-dipping of various steel fabrications, however, may result in irregular heating for the fabrication while in the galvanizing bath, which may result in distortion.

Suspension

While the metal is being taken out of the galvanizing bath, the components need to be suspended in a manner that let the liquid zinc drain. The proper positioning will ensure that no excess zinc is left on the metal.

It is crucial that the right process is used for galvanizing metal. Be sure to keep this in mind when any type of project involving this material is done. Being informed is the best way to handle this type of process, regardless of how big or small it may be or how complex it may seem.
