Certified Member of the AGA

The American Galvanizers Association (AGA) is a non-profit trade association dedicated to serving the needs of after-fabrication galvanizers, fabricators, specifiers, architects, engineers, and contractors. The AGA provides technical support on today’s innovative applications and state-of-the-art technological developments in hot-dip galvanizing for corrosion control. The AGA also provides a number of services to galvanizers and zinc producers in the industry. The AGA celebrates 87 years of preserving the past, enhancing the present, and protecting the future.

Galvanizing is an art.

Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent premature rust and corrosion.

Degreasing/Caustic Cleaning

First the steel is immersed in an acid degreasing bath or caustic solution in order to remove the dirt, oil, and grease from the surface. After degreasing, the steel is rinsed with water.


The steel is then immersed in an acid tank filled with either hydrochloric or sulfuric acid, which removes oxides and mill scale. Once all oxidation has been removed, it is again rinsed with water.


The purpose of the flux is to clean the steel of all oxidation developed since the pickling of the steel, and to create a protective coating, before entering the galvanizing kettle.

Zinc Bath

Steel is now ready for immersion in the molten zinc. The steel products remain in the kettle until the temperature of the steel has reached the temperature required to form a hot-dip galvanized coating.

Post Treatment

Once removed from the kettle, it may receive a post-treatment to enhance the galvanized coating. One of the most commonly used treatments is quenching. Other finishing steps include removal of zinc drips, by grinding or filing them off.

Proper Drainage and Venting

The primary reason for vent and drain holes is to allow air to be evacuated, permitting the object to be completely immersed into cleaning solutions and molten zinc. Proper sizing and location of the holes make it safer to galvanize and provide and optimal finish. The secondary reason for venting/drainage is to prevent damage to the parts.

Wayne Gretzky Estates Winery

The 23,000-square-foot winery and distillery, marks the largest single investment in a winery to date by Andrew Peller Ltd, located in Niagara-on-the-Lake. The design is a modern barn-like structure meant to pay homage to the hockey barns Canadians, like Gretzky, grew up playing hockey in. This distillery features memorabilia from the Great One’s career, winery and distillery tours and tastings, an outdoor whisky bar and a seasonal hockey rink.

Audi Queensway

The new Audi Queensway is a 65,000 sq.ft. dealership located at The Queensway and East Mall featuring to the new Audi identity. The dealership includes a 20,000 sq.ft. showroom, 10,000 sq.ft. used car display, and a state of the art service facility with equipment able to handle over 25 vehicles at any given time.

407 ETR

Highway 407 ETR is one of Ontario premiere tolled highways that is continuously in development for new interchanges and widening roads.

Yorkdale Expansion

In 2016, Yorkdale has opened the doors to a 300,000 square foot, $331 million expansion. This wing features a 112,000 square foot corridor featuring some of the finest fashion names, the most-coveted luxury labels and every must-have brand making it in every sense, the Centre of Style. Yorkdale is one of Canada’s leading shopping destinations with the country’s highest sales per square foot ($1,610).

Safety Fall Arrest Anchors

Many variations of roof anchors, davits and platforms are used for window washing equipment and fall protection equipment. Each building or structure requires different safety measures and layouts, but all should be hot-dip galvanized due to the extreme weather conditions that they incur.

BMO Field Renovations

In 2015-2016 the MLSE had invested a large sum of money to BMO Field renovations. The stadium now can reach up to 28,000 in seating, where the north and south end were revitalized with a new seating.

Dedicated To Our Environment:

Sustainable Development

Sustainable development involves balancing local and global efforts to meet basic human needs without destroying the natural environment. With hot-dip galvanizing, zinc coatings lengthen the life of steel structures by keeping steel performing in its optimal condition. This benefit alone enables a huge preservation of natural resources by reducing waste that occurs naturally. As a result, steel and zinc both serve as sustainable materials in today’s environmental conscious society.
