Perhaps no other residential high-rise has created more buzz than the highly-anticipated Porsche Design Tower in Sunny Isles, Florida. A collaboration between Dezer Development and the Porsche Design Group, the 60-story, 132-residence luxury tower designed by Sieger Suarez Architects promises to deliver a new standard of cool.

The Department of Defense (DoD) published the Unified Facilities Criteria (UFC) 4-010-01 Antiterrorism Standards for Buildings as a mandatory guideline to mitigate the threats of terrorism against buildings and ensure the safety of the individuals that inhabit them. It applies to all newly constructed DoD Components, DoD inhabited buildings, billeting and high-occupancy housing, as well as already inhabited buildings where the renovation costs are 50% or more than the value of the building (for a complete list, please see UFC 4-010-01 section 1.8).

CSSBI Position Paper on CGSB Standards for Prefinished Sheet Steel Cladding The National Building Code of Canada 2010 includes references to two documents published by the Canadian General Standards Board (CGSB) dealing with prefinished sheet steel cladding. These documents are: • CAN/CGSB-93.3–M91 Prefinished Galvanized and Aluminum-Zinc Alloy Steel Sheet for Residential Use • CAN/CGSB-93.4–92 Galvanized Steel and Aluminum-Zinc Alloy Coated Steel Siding, Soffits and Fascia, Prefinished, Residential It is important to realize that there are no sheet steel products currently manufactured in Canada that meet the requirements contained in these CGSB standards.

About the ProjectTowering above the Dubai skyline, the Burj Khalifa is symbolic of the city’s emergence as one of the world’s top business and tourist destinations. The magnificent tower houses residences, a hotel and various commercial spaces, but its most popular attractions are the two observation decks located at the 124th and 148th floors. For visitors, the enthralling experience of visiting At The Top starts right from the moment they start to queue up to book their tickets. An extraordinary union of tasteful design, precision engineering and meticulous craftsmanship, the entrance lobby to the observation deck was created to give visitors a small glimpse of the beauty that awaits them a hundred storeys higher.The ChallengeWhile procuring the glass for the lobby to Dubai’s most well-known tourist attraction, we left no stone unturned in sourcing the highest grade materials. The customer had very specific needs regarding the colour of the panels. Achieving the right PVB colour combination was one of the biggest challenges we faced on this project. Further, we had to ensure that the glass used was durable and the coloured films did not fade over time. Working with Seele proved to be both demanding and rewarding. The company, known for developing Apple stores across the world, wanted to inspect every single pane of glass so that it met their high quality requirements. 

Sustainability, durability, fire resistance, structural performance and cost-effectiveness are some of the strongest reasons for using structural steel or cold-formed steel framing in mid-rise building construction. As a dependable, noncombustible material, steel-framed structures provide a wise investment for builders and the occupants who live and work in them. Steel structures provide long-term, consistent performance. • Steel framing will not rot, warp, split, crack or creep. • Steel framing is not vulnerable to termites. • Steel framing does not expand or contract with moisture content. • Steel framing is produced in strict accordance with national standards, with no regional variations. Steel is a noncombustible material and will not contribute to the spread of a fire. • Because steel is noncombustible, it reduces the fire risk to occupants, firefighters and property/business owners. Steel framing improves design efficiency, saves time, and reduces costs. • Steel framing provides a significantly greater strength-to-weight ratio than wood. • Steel framing allows for larger bays and wider frame spacing than wood construction. • Increased flexibility in bay spacing and framing layout maximizes usable floor space for owners and tenants. • Steel is typically fabricated off-site, reducing on-site labor, cycle time and construction waste. • Shorter construction time results in earlier occupancies and lower financing costs. Steel structures perform well during earthquakes and other extreme events. • Steel is a resilient material, with reserve strength and ductility that result in significant advantages in natural disasters such as hurricanes and earth- quakes, and in other extreme events like fire and blast. • Steel construction is engineered to provide a reliable, consistent load path. • Steel construction employs quality control and quality assurance procedures to ensure that the project requirements are met. Steel framing provides environmental benefits and complies with sustainable building standards. • Steel framing results in less scrap and job site waste than lumber. • Structural steel is continually recycled with a current recycling rate of 98 percent, meaning that these steels will still be in use hundreds of years from now, lessening impacts on future generations. • Steel, when recycled, loses none of its inherent properties and can be recycled into different products such as cars, bridges, cans, etc. • Steel can be used to comply with the requirements of sustainable design standards such as the International Green Construction Code (IgCC), ASHRAE Standard 189.1 (Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings), and the National Green Building Standard (ICC-700). Steel can also provide credit points for green building rating systems like the USGBC’s LEED (Leadership in Energy and Environmental Design) and the Green Building Initiative’s ANSI/GBI-01 (Green Building Assessment Protocol for Commercial Buildings).  

Four Key Components Constitute Prefinished Sheet Steel Prefinished sheet steel for construction consists of four major components: the sheet steel itself, a metallic (zinc or aluminum-zinc alloy) coating, chemical pre-treatment and primer, and a top coat. Each performs an important role in providing designers with a high quality, aesthetic, cost competitive and corrosion-resistant material. The backbone of the system is sheet steel, an ideal material for covering large surface areas because of its economy and high strength-toweight ratio. Protection against the demanding Canadian environment is provided by the metallic coating, one of the most effective methods of protecting bare steel from corrosion. Both zinc and aluminum-zinc alloy provide a tough, non-porous coating

A question that homeowners often ask about steel roofing is “Will a steel roof be noisy when it rains?”. We’ve created this fact sheet to help answer that question. Residential steel roofing is available in many shapes and forms. The forming process provides not only strength, but when coupled with high quality build finishes, absorbs and deadens much of the noise. With the home insulation standards of today, you should not notice any difference in noise levels between roofing materials. 

It’s a fact that buildings consume two thirds of all the electricity produced in North America and one third of all the energy produced in North America. While it is recognized that cooling and heating costs can be reduced by adding insulation under the roof surface, there is a diminishing return on the strategy of increasing insulation to conserve energy costs. This is where “cool roofing” can play a role in further reducing the energy consumed, and in minimizing the Heat Island effect created in the big urban cities. Cool roofing relies on the properties of reflectivity and emissivity of the roofing material. Reflectivity Reflectivity is the ability of the roof to reflect solar radiation back into the atmosphere. Its primary measure is solar reflectance - the proportion of the total solar radiation that is reflected back to the atmosphere. Any solar radiation that is not reflected is absorbed into the building envelope, requiring further energy to cool the building; or partially convected into the atmosphere increasing the ambient air temperature in the surrounding environment (Heat Island effect). The measure of reflectivity is the Solar Reflectance Index (SRI) which takes into account the properties of the material as well as the cooling effect of wind passing over the roof. The SRI for a low slope roof will be 0 for standard black (reflectance 0.05, emittance 0.90) and 100 for standard white (reflectance 0.80, emittance 0.90).

Steel’s versatility and durability have made it an ideal building material for various construction projects for the past 150 years. Over that time, steel has earned a welldeserved reputation for economy and proven performances with long life cycles. Combine these benefits with steel’s ability to be recycled and engineered for retrofits, and steel cladding undoubtedly will become the number one choice of building materials across all industries. Recently, the Canadian Sheet Steel Building Institute commissioned a non-biased third party, Strategic Research Associates, to examine the state of the Canadian farm. Specifically, the study examined farmers’ steel cladding purchasing habits and steel cladding usage over the past 10 years. The study queried 471 farms across Canada with 43 farms in British Columbia; 96 in Alberta; 96 in Saskatchewan/Manitoba (combined); 97 in Ontario; 96 in Quebec; and 43 in the Atlantic Provinces. The results are within ± 4.5 percentage points for complete representation of all Canadian farms and are as follows:

The new Robert B. Aikens Commons at the University of Michigan Law School was built on an unused grassy courtyard between Hutchins Hall and the legal research building. The proximity of the new common area to historic Hutchins Hall posed a unique challenge. The building code required a 2 hour fire rated barrier between them. The architects specified SuperLite® II-XL 120, a clear, fire resistive glazing product that meets the ASTM E-119 wall standard for up to 2 hours.

Al Wasl Plaza was the heart of Dubai Expo 2020 and continues to remain the focal point of Expo City. The central dome, surrounded by a decorative garden and five buildings, truly reflects the theme, Connecting Minds, Creating the Future. Working on the Al Wasl Plaza required careful thought and consideration. We had to ensure that the three office buildings and two hotels enjoyed unobstructed views of the garden and dome while maintaining energy efficiency and privacy.  The project was designed by Chicago-based architecture firm Adrian Smith + Gordon Gill. Since the project was part of Expo 2020, which invited representatives from around the globe, we had to ensure we met and exceeded global glass and glazing standards. We understood that the buildings were the supporting cast for the dome and gardens, yet they played a crucial role in making the entire plaza the focal point of the Expo.

Preface One of the objectives of the CSSBI and its members is the development of standards and technical publications that promote safety, performance and good practice. This "How To Series" of publications is an educational tool intended to give guidance to anyone specifying sheet steel building products. This particular publication is published as an aid to building owners as well as roofing and siding installers. It offers simple and practical recommendations for the selection, application and installation of light gauge steel cladding. This is a generic guide giving the basic details and should only supplement the specific recommendations or guidance published by the manufacturer appropriate to their own products. The views expressed in this guide are a collection of installation techniques and do not necessarily reflect those of all member companies of the CANADIAN SHEET STEEL BUILDING INSTITUTE. The material presented in this publication has been prepared for the general information of the reader. While the material is believed to be technically correct and in accordance with recognized good practice at the time of publication, it should not be used without first securing competent advice with respect to its suitability for any specific application. Neither the CANADIAN SHEET STEEL BUILDING INSTITUTE nor its Members warrant or assume liability for the suitability of this bulletin for any general or particular application.

The construction industry is a vital part of the growth and success of a country. It is responsible for building the physical infrastructure that provides transportation and facilities for citizens, businesses, industries and institutions. Construction has a major influence on the economic wealth, societal well¬being and sustainability of the built environment. The Canadian construction industry employs more than 1.2 million people. In 2010 it accounted for 6% of Canada’s gross domestic product (GDP), with a total value of 73.8 billion dollars. From 2000 to 2010, the GDP from construction increased 42.7% whereas GDP for all industries increased 20.2%.(1) Construction also has a profound impact on our natural environment. In North America, the built environment accounts for approximately one third of all the greenhouse gas (GHG) emissions, as well as energy, water and materials consumption. Given the increased awareness of “green” construction, there is growing interest in using steel because of the major recycled content and recyclability attributes it provides to architects, engineers and specifiers in the construction industry. The steel industry, through the Canadian Sheet Steel Building Institute is committed to providing steel solutions that promote the use of sustainable materials in construction applications. This fact sheet provides an overview of the two main methods used to produce steel, and describes the recycled content of the steels used to manufacture building products such as roofing, cladding, decking, structural and non-structural framing and the many other construction products used in the industry. Once iron ore is extracted and refined into steel, its life never ends. This makes steel an ideal material to deploy in sustainable strategies for the construction industry. Today’s steel is produced using two technologies both of which require “old” (recycled scrap) steel to make “new” steel. The combination of these technologies enables Canadian steel mills the flexibility to produce a variety of steel grades for a wide range of product applications
