Galvanizers Association is the source of free information and advice about hot dip galvanizing, cost effective corrosion protection and the galvanizing industry.
In common with many businesses GA have taken all necessary steps to comply with the latest government advice on Covid-19 (Coronavirus). We are still operating all services including our free technical helpline. Please do continue to contact us on +44 (0) 121 355 8838 or via email ga@hdg.org.uk if you need any assistance on design, specification or advice on performance.
Formation of rust on steel surface (time-lapse)
Steel is a strong and versatile material with uses in many different industries. It has one of the highest strength to weight ratios of construction materials and is 100% recyclable. However, in order to enhance and protect this vital asset corrosion, protection is essential.

New Book from GA
In response to the international interest being shown to a former industrial building that has been cloaked in galvanized steel, Galvanizers Association has produced a detailed account of the architectural statement that is the Copenhagen DLG Silo.
Designed by COBE with clients Klaus Kastbjerg and NRE Denmark, this former grain storage facility, the largest industrial building in the area, has been reinvented as ‘The Silo’, housing residential apartments and public functions…
Galvanised steel is all around us and plays a vital role in contruction, transport, agriculture and utilities.

This map provides data for the atmospheric corrosion rate of hot dip galvanizing. Search for a location and hover over the 10 km grid to obtain the corrosion rate. The map legend can be used to find the average life of an 85 µm coating within the area.
| Corrosion rate key | |||||
| Average Corrosion Rate(µm/year) | 0.5 | 1 | 1.5 | 2 | 2.5 |
| Average Life of 85µm galvanized coating(years) | 170 | 85 | 57 | 43 | 34 |
Average background corrosion rates for zinc. Each grid square is 10km².
