What’s The Galvanizing Meaning? Steel is used in a variety of areas and is one of the most popular and versatile materials. Its surface requires special care due to its feature of reacting in contact with the environment and corrosion. The galvanizing process allows the steel part to obtain a protective layer. It is enough […]

Galway’s Pálás cinema designed by dePaor Architects, won the Detail Award in the Galvanizers Association GAGA competition. Galvanized steel was chosen in Pálás for its texture and colour, flat against the west of Ireland sky. It is good with limestone and concrete and it weathers to a soft grey and chimes with street furniture. Pálás

During the hot dip galvanizing process, iron and steel components are heated to the temperature of the galvanizing bath, of about 450°C. While the steel is immersed in the molten zinc, layers on zinc-iron alloy are formed on the surface by a process of diffusion. When the steel components are withdrawn from the bath
Considerations before Hot Dip Galvanizing: Steel Composition Read More »
The chemical composition and the condition of the steel which forms the base material are vitally important for successful hot dip galvanizing. They affect the thickness, structure and quality of the galvanized coating. For best results, it is just as important for the customer to ensure that the construction and design are suitable for galvanizing.

When two dissimilar metals come into direct contact and an electrolyte such as moisture is present, a battery cell is created and an electrical current flows. This causes the more electronegative or anodic metal as determined from the electro-chemical series (see below) to corrode more rapidly. This means that galvanizing being a zinc

It is 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
