What is the difference between a cold-galvanized fence and a hot-dip galvanized fence?

Pulished on Aug. 10, 2019

Where is the difference between cold galvanized guardrail network and hot galvanized guardrail network? Following the Custom Field Fence supplier would like to share with us.

Galvanized technology is widely used in the guardrail industry, this process is also divided into hot galvanizing and cold galvanizing two ways, and what are the differences between these two kinds of galvanized technology? Let's look at the difference between hot galvanizing and cold galvanizing:

Hot dip galvanizing is dip plating in the molten zinc after heating, and the galvanizing tube is gradually blocked on the metal surface through single current in the galvanizing bath. Hot dip galvanizing process production speed, galvanized layer thick, consumption of zinc metal. Ordinary galvanized slow speed, galvanized thin. Such as the Hot Dipped Galvanized Wire Field Fence.

Cold galvanizing High Tensile Steel Wire Field Fence refers to electroplating, hot galvanizing is the zinc that an object is plated in molten zinc. The difference between the two is that the former has poor corrosion resistance, while the latter has good corrosion resistance. Hot dip galvanizing can be maintained in the outdoor environment for more than ten years. Generally, steel structures with small components use this process.

Hot Dipped Galvanized Wire Field Fence

Know the difference between hot galvanizing and cold galvanizing High Tensile Steel Wire Field Fence, let's have a look at the specific what is hot galvanizing and cold galvanizing.

What is hot dip galvanizing?

Hot dip galvanized, also known as hot dip galvanized, it is in the high temperature of the zinc ingot melting, in the addition of some auxiliary materials, and then the metal structure pieces immersed in the galvanized tank, the metal components attached to a layer of galvanized layer, hot galvanized advantage lies in its strong corrosion resistance, galvanized layer of adhesion ability and high hardness. The disadvantage is that the price is relatively high, a large amount of equipment and site investment is required, the steel structure is too large and not easy to put into the galvanized tank, in addition, the steel structure is relatively thin, heat is easy to deformation. We often say that the zinc rich coating generally refers to the zinc powder containing anti - corrosion coating.

What is cold galvanizing?

Cold galvanizing is electric galvanizing. The cold galvanizing process is used to protect the metal from corrosion. For this purpose, a coating of zinc filler is applied to the surface of the protected object by any coating method. After drying, a layer of zinc filler is formed. Suitable for repair work (i.e. in the course of repair work, only where the surface of the protected steel is damaged, the surface can be reapplied after repair). Cold galvanized process used for all kinds of guardrail products and structures of corrosion protection, this process is very little galvanized, only 10-50g/ m2, its own corrosion resistance is much different than hot dip galvanized. So the price of electric galvanizing is relatively cheaper.
