Variations in initial coating appearance from one project to the next and the natural weathering of HDG steel often cause confusion
|
Hot-dip galvanizing has been applied to reinforcing steel in concrete used for precast panels, barriers, and bridge decks since the early 1970s. While new technologies have surfaced in decades past, none have matched the performance or economic savings that galvanized reinforcing steel has delivered.

As specifiers of commercial buildings look to achieve durable and long-lasting structures, many are turning to hot-dip galvanizing (HDG) as a method for protecting structural-steel members against atmospheric corrosion for many decades.
|
Specifiers are looking to hot-dip galvanize exterior architecturally exposed structural steel (AESS) to protect their designs for generations to enjoy. However, this practice can lead to friction between the architect, steel fabricator, and galvanizer, as there are misconceptions about the appearance of hot-dip galvanized steel.

The Whistler/Blackcomb Cloudraker suspension bridge in British Columbia has won the ‘Most Distinguished’ award by the American Galvanizers Association (AGA).
|
At this year’s American Galvanizers Association (AGA) awards, four Canadian projects were celebrated, including a Fort McMurray, Alta., project recognized as Most Distinguished.
|
As more owners and design/construction professionals look toward constructing steel bridges that can last a century, it is imperative to evaluate the corrosion protection systems used to ensure these structures meet the long design life without significant deterioration, and without significant cost.

The American Galvanizers Association (AGA) announced the winners of its 2015 Excellence in Hot-dip Galvanizing (HDG) Awards, including three Canadian projects. More than 100 projects were submitted representing the versatility of HDG.
