Essential Insights on Galvanized Steel Sheet Metal
Galvanized Steel Shines in Restoration of Canadian Parliament Buildings
In the heart of Ottawa, Ontario, the Canadian Parliament Buildings have undergone a significant transformation, with several landmarks receiving restoration work involving a sturdy and durable material: galvanized steel sheet metal.
The iconic Peace Tower, Centre Block, Library of Parliament, West Block, MacKenzie Tower, East Block, and the Office of the Prime Minister and Privy Council (formerly the Langevin Block) have all been restored using this versatile material.
Heather & Little, a company renowned for its expertise in galvanized steel sheet metal and other specialized materials, has played a key role in these restoration projects. Their expertise has ensured that the historic buildings maintain their integrity while gaining improved corrosion resistance and durability.
Galvanized steel sheet metal is particularly suited to outdoor applications, such as fences, roofs, gutters, and garage doors. It is steel coated with zinc oxide, making it resistant to rust. This property has been crucial in the restoration projects, as the buildings' outdoor elements have been protected from the elements.
The Centre Block's copper roof, for example, was replaced with a new building envelope, including an air barrier membrane and batten seam copper roofing. Galvanized steel was used in structural areas for added durability. Similarly, the East Block's slate roofs were replaced with copper, with galvanized steel backing for additional strength.
The Office of the Prime Minister and Privy Council (formerly the Langevin Block) restoration included the replication of stamped sheet metal decorations and the installation of 20-ounce copper sheets. The West Block's MacKenzie Tower restoration involved the use of galvanized steel to support hidden structures, while restored copper and lead protected masonry and decorative details.
In addition to its structural benefits, galvanized steel sheet metal can also be used for artistic purposes. The Peace Tower, for instance, features intricate copper roofing, with the modern air-vapour barriers and wood battens being made from original 20- and 24-ounce copper sheets.
Galvanized steel sheet metal is available in various sizes, with the thickest being an 8 gauge (0.1681 inches thick) and the thinnest being a 32 gauge (0.0134 thick). It can have a natural silver finish or a powder-coated finish, which is a durable and resistant paint that comes in various colours.
The Library of Parliament project involved the installation of 1,390 square metres of galvanized iron and lead-coated copper, along with stainless steel gutters and restored ornamental elements. Heather & Little has been involved in the restoration of multiple Parliament Hill landmarks, demonstrating their commitment to preserving these historic buildings.
In conclusion, the use of galvanized steel sheet metal in the restoration of the Canadian Parliament Buildings has provided a balance of strength, corrosion resistance, cost-effectiveness, and long-lasting protection in outdoor and harsh environments. This versatile material has proven to be an invaluable asset in preserving these national treasures for future generations.
