What is Galvanizing?
Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a thin protective layer of zinc to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the components are submerged in a bath of molten zinc. Alternatively, a layer of zinc can be applied by brush, roller or spray. This is carried out with a paint called Zinga. Zinga is a cold galvanizing paint that test show will offer greater protection against rust over hot dip galvanizing. corrosion of zinc is much slower than steel or iron therefore the life of the metal can be dramatically extended. Due to the alloying of the Zinc to the iron, cathodic protection is achieved. Previously hot-dip galvanized steel can simply be over coated with Zinga but any rust should be removed by mechanical means before application. Galvanized steel resistance to rust corrosion depends largely on the thickness of the protective galvanized zinc coating that is applied , we strongly recommend at least 2 coats of Zinga are applied allowing the paint to dry between coat. Galvanized steel will last in excess of 25 years but factors such as high humidity, above 60% and attack from de-icing salt used on highways.
Zinga's galvanizing paints unique formula provides environmentally safe cathodic protection to steel. Zinga cold galvanizing paint is comparable with hot-dip galvanising, with the added advantage that it can be applied by brush roller or spray as though it were a paint.
Zinga 96% Cathodic Protection has provided durable protection to a multitude of complex steelwork projects throughout the globe. Some of the well known architecture protected in Zinga include the Bird's Nest stadium in China, the Koisk Louter in Ghent, Runcorn Energy Plant in the UK, Guangzhou Baiyun International Airport and Mumbai Domestic Airport. Zinga is also approved for London Underground use for the protection of steelwork.
Zinga galvanizing paint is also suitable for the protection of boat hulls, electricity pylons, off shore oil rigs, power stations, pier legs, bridges, water turbines, car chassis', airport exteriors, tanks and more. We have a huge range of case studies available - click here to see Zinga projects on our Knowledge Hub.
