Please make sure you remove any welding slag, paint and heavy grease from the piece before we receive it.

Then we'll do the rest.

2. Preparation by Birtley

• Alkaline or acid dip for final degreasing.

• Cold water rinse and then 'pickling' - hydrochloric acid dip to remove rust and mill scale. Rinse again.

• Dip in flux solution - typically 30% zinc ammonium chloride - to remove last traces of surface oxide so that the molten zinc properly wets the steel.

​

• Pieces are dipped into a bath of molten zinc. Our advanced gas burning technology heats the bath very efficiently, with exhaust heat harnessed to warm up preparation chemicals.

• Any zinc that does not coat the metal remains in the bath or re-use.

• Galvanizing residues are recovered and zinc recycled for further use.

• Recycled zinc from other sources, such as zinc scrap, is often used to further improve the efficient use of materials.
