Painting Hot Dip Galvanised Steelwork
Hot Dip Galvanizing has long been recognised as the most successful method of providing corrosion protection for steelwork. For some however, the perceived difficulty in applying a subsequent paint coating on top of it has limited its use – and caused specifiers to seek other forms of corrosion protection.
The reason that many paints tend not to adhere well to freshly galvanized steel goes back to the original use they were intended for. These paints were typically designed for application directly to steel, which is a ‘ferrous metal’. Galvanizing, on the other hand, is zinc based and as zinc is a ‘non-ferrous metal’ a different solution is required.
Galvacoat was originally formulated for direct application to zinc to allow hot dip galvanized transformer tanks be painted over twenty years ago, Galvacoat is still widely used for this purpose and is also approved for use on Electricity pylons.
Nowadays Galvacoat is used across a wide range of applications including gates, railings and balconies as well as on structural steelwork and street furniture.

Hot dip galvanizing – continued professional development (cpd)
Galco provides a full technical service for Engineers & Architects in Ireland including literature, telephone enquiries, plant visits and in-house CPD presentations.
The course describes what Hot Dip Galvanizing is and corrosion protection it provides. It also includes the process of application, the relevant standards, quality assurance, on-site inspection, life expectancy and sustainability. It will also cover the specification of Hot Dip Galvanizing and some important design considerations to be considered.
Participants will get a clear understanding of the Technical, Architectural and Environmental advantages to using Hot Dip Galvanizing along with recent examples of practical application.
In order to keep you updated with the latest developments relating to Hot Dip Galvanizing we offer CPD style presentations. We arrange these in your office at a time convenient to yourselves.
Learning objectives
The presentations have been designed in conjunction with the Galvanizers Association and cover the following areas:
- Coating characteristics
- Specification & standards
- Design for galvanizing
- Coating performance
- Galvanizing process
- Applying colour
- Corrosion protection
- Case histories
- Costs & economics
- Sustainability
