It is a common misconception that any zinc coating can be termed as galvanizing but this is in fact not the case as there are many different processes by which a zinc coating may be applied.
Hot Dip Galvanizing refers only to coatings formed by immersing steelwork into molten zinc. However, there are two variations of the Hot Dip Galvanizing processes: Batch Galvanizing and Pregalvanizing.

Batch Hot Dip Galvanizing
This process is used to coat fully fabricated articles and involves chemical cleaning of work prior to immersion in the galvanizing bath and is specified by BS EN ISO 1461.
Pregalvanized Steel Sheet
This is the most widely used pregalvanized product and is specified by BS EN 10346. Sheet is uncoiled and passed through a reducing atmosphere prior to immersion in the galvanizing bath for a relatively short period of time.
Coating Comparison
Both batch hot dip galvanizing and pregalvanized coatings have different characteristics and the table in the datasheet summarises these.
