Galvalume Plus™ accentuates the new tent-like roof

The unpainted 30,000 shingles in “À la Canadienne” shingle pattern, manufactured from .45mm and .61mm (.0179” and .0239”) Galvalume Plus™ help the tent-shaped roof of the church, now functioning as a public library, brilliantly reflect snow and sky and reach to the heavens. The shingles blur the distinction between snow, roof and sky, and complement the glass-walled extensions to the building.

The architects teamed-up to complete the Monique-Corriveau Library, which involved an addition to and conversion of the St-Denys-du-Plateau church in Québec City. Built in 1964, the church is a landmark example of modernism in the region, featuring a tent-like form and it served parishioners until it was closed in 2009. In the fall of 2013, after being restored and expanded, it reopened as the Monique-Corriveau public library. The signature exterior feature of the original church, designed by the architect Lean-Marie-Roy, is its tent-like roof. Its guy-like rafters, exposed between the bottom edges of the roof and the ground, reinforce the illusion of a revival church tent.

ArcelorMittal Dofasco’s Galvalume PlusTM is an unpainted steel sheet product that starts with our Galvalume™ substrate and its highly corrosion resistant 55% aluminum – 45% zinc alloy hot dipped coating. A clear, organic resin coating is applied to both sides of the substrate, using sophisticated reverse roll coaters. Galvalume Plus™ offers strength, superior corrosion resistance and an attractive bright appearance that provides excellent heat reflectivity.

The roof was originally covered with white and the later, with somber black asphalt shingles that visually weighed down the church and pinned it to the ground. As part of the restoration, the shingles were removed. A new roof which included a roof membrane, plywood, batten, rigid insulation and decking was put in its place. Then installers fastened the shingles manufactured from Galvalume Plus™ to the new roof.

Toiture Qualitoit Inc., now defunct, cut the 914mm x 2,438mm (36” x 96”) sheets of Galvalume Plus™ into 914mm x 304.8mm (36” x12”) shingles, and embossed them with a pattern which Toiture Qualitoit Inc. called “À la canadienne”.

The 2,800m2 (30,139 sq. ft.) worth of shingles, by virtue of their small size, hug the complex curves of the roof, but they also effectively sheath the 27.43m (90 ft.) high steeple at the roof’s other end. The peak tops out at about 26.82m (88 ft.). Qualitoit Inc. used Galvalume Plus™ in two thicknesses, .45mm (.0179”) for the “flat” portion of the roof and .61mm (.0239”) for some of the roof details, according to Denis Blanchet, who was president of Qualitoit Inc. when the conversion of the church was undertaken. He is currently the estimator and project administrator with Toiture 4 Saisons.

Behlen’s Design and Manufacturing Expertise –three Indoor Arenas in Georgia

Steel is so incredible for construction projects that it is known the world over for its versatility and durability. That is why, when it came time to build three indoor arenas in the Republic of Georgia, Behlen Industries was tapped to construct these steel-based structures for all to enjoy. “Two of them are the same size and the third is a little bit bigger,” said Dave Fletcher, Director of International Sales for Behlen in an interview with Steel Design.

Fletcher went on to add that it was a long process to get the deal done in Georgia in order to build these structures but, by partnering with the right people the project became a reality. “One of the arenas is in Plavi the other one is in Gori, which is (interestingly) where Joseph Stalin […]


Gary W. Harris Canada Games Centre, Red Deer College

When the City of Red Deer approached Red Deer College about hosting the 2019 Canada Winter Games, it was a catalyst for finally realizing a dream. The college had been planning a new facility focused on health education, sport and recreation for years. The new Gary W. Harris Canada Games Centre will host five Canada Winter Games events, including Short Track Speed Skating, Figure Skating, Badminton, Wheel Chair Basketball and Squash.

“We envisioned a facility that would be learner-centred; support teaching, learning and the student experience; provide for sport and lifestyle fitness and be available for community use,” says Doug Sharp, the college’s Director of Capital Projects. “The facility would contribute to the economic, social and inclusive wellbeing of the central Alberta region and would become […]

LustreLok™ – the Advanced Acrylic Coating for Galvanized Steel

LustreLok™ is a thin, clear organic coating, applied to both sides of the galvanized steel as a final protective layer over the zinc coating. LustreLok provides an attractive appearance and enhances the traditional look of galvanized steel. The application of an organic coating eliminates the need for ArcelorMittal to apply conventional chemical treatment and vanishing oil.

This enhancement offers our customers and users the following benefits: REDUCED COSTS: • The product is designed to be roll formed dry, which eliminates the need for lubricants • Lower maintenance costs – reduced coating build-up and reduced tool wear will extend die life. • Improved productivity – extended die life results in longer production […]


Prefabricated Light Steel Framing and Prefab Panels save time

The reality behind Interbuild Limited’s pre-fabricated lightweight cold formed steel wall, structural floor and roof framing systems is simplicity and efficiency.

Interbuild’s pre-fabricated steel wall panels, together with a faster construction time make these materials a no-brainer – a cost-effective alternative to traditional building. That is why Habitat For Humanity used this method for a recent project in Hamilton. Cold formed steel provided lower construction costs, reduced insurance costs, plus the added benefit of non-combustibility. “The […]
