CHOOSING a corrosion protection system for steel represents a critical step in the design of any project, large or small. The estimated annual cost of corrosion is a staggering 3 per cent of the Australian GDP, and the lifecycle cost of corrosion-related maintenance is, on average, between two and five times the initial cost of construction.

The success of hot dip galvanizing of steel is well documented: an established, cost-effective answer to extending the life of uncoated steel in atmospheric situations and superior to any other protective coating, the method continues to find new applications in almost every field of engineering.

Established in 1963, Galvanizers Association of Australia (GAA) comprises many of Australia, New Zealand and Asia’s leading galvanizing companies. GAA’s hot dip galvanizing members include 35 plants, from every capital city and many regional centres in Australia, which employ about 3000 people and have a processing capability to protect more than 750,000t of steel per annum.

The GAA’s most important goal is to promote the development of both established and innovative uses of hot dip galvanized coatings, as well as improving techniques, safety, efficiency and sustainability in the hot dip galvanizing industry.

Providing technical consulting services on a not-for-profit basis, GAA helps its member companies provide the highest standards in design and quality of galvanized products, and assists consumers in finding cost effective, well designed galvanized products applicable to their individual needs.

The industry group provides free technical publications and practical assistance on all aspects of design, application, processing, bolting, welding and painting of galvanized steel, with a wealth of information readily available from the GAA website or from any of the leading galvanizers listed in its members’ directory.

The website – – was designed to assist designers, specifiers, materials engineers, consultants, and fabricators to protect and improve their steel products. The website’s information covers important aspects of the galvanizing process and the properties and applications of galvanized coatings; it also includes sections that feature the design and specification of galvanized steel, fabrication methods including bolting and welding, and the painting of galvanized steel.

The GAA has also developed an innovative micro-site to allow users to calculate the initial and total life costs of more than 30 other corrosion protection systems against hot dip galvanized steel.

Based on information provided by the user, the Life-Cycle Cost Calculator (LCCC) generates a customised report detailing all costs associated with maintaining a structure across its service life, including the time value of money.

Interested parties can access the Life Cycle Cost Calculator at More information on lifecycle costing of hot dip galvanized coatings, including the sustainable features of the process, is available from the GAA website.
