Galvanizers Association is the source of free information and advice about hot dip galvanizing and the galvanizing industry. Feel free to contact us on +44 (0) 121 355 8838 if you need any assistance on design, specification or advice on performance.
Why do I get variation in the colour of galvanized steel?
Specifiers and end users often anticipate that batch hot dip galvanized steel will have a uniform bright colour and appearance. In practice (…) some variation in coating appearance might occur.

We have recently launched ‘the zinc tank’, where we’ll inform you about the latest technical insights into the process, performance and the many uses of galvanized steel.
Featured Case Study
The small footprint is matched by a small developmental impact; a new building has been reassembled from the old parts of the original building. The walls have been augmented with breathable insulation and the roof has been decked out with solar cells.
