CSSBI SSF 24-07: Natural Finish Metallic Coatings - Attractive but not Architectural
Trimet Building Products
Architects and Specification Writers are increasingly selecting unpainted metallic coated steels for architectural roofing and cladding applications on building exteriors where they want a “Silver” metallic finish. This is occurring more frequently, and even on “prestige” type projects. The Canadian Sheet Steel Building Institute whose fabricator members manufacture a wide variety of building panel profiles for roofing and cladding applications, are being asked to supply unpainted (natural finish) galvanized or resin coated 55% Aluminum-Zinc coated steel for these architecturally exposed end uses. Oftentimes, these materials are specified because the designer finds the natural finish of these products very appealing and sometimes because of material cost savings opportunities. This Fact Sheet has been developed to provide guidance in material selection and provide information on the Architectural Metallic Finishes that are available for highly visible steep slope roofing and cladding applications.
COOL METAL ROOFS ARE ENERGY-EFFICIENT AND COST-EFFECTIVE
Trimet Building Products
Buildings consume one-third of all energy and two-thirds of all electricity generated. Cool metal roofs can help reduce energy consumption by lowering cooling loads with their wide array of finishes, designs and colors.Cool metal roofs are energy-efficient. • The roof can have the greatest impact on the energy use of a building. On a typical summer afternoon, a light-colored, more reflective roof that reflects 80 percent of sunlight will stay about 310C (550F) cooler than a darker roof that reflects only 20 percent of sunlight, as reported by the Heat Island Group of the Lawrence Berkeley National Laboratory. • Cool metal roofs are an excellent option for commercial retrofit applications because they can be efficiently installed with above-sheathing ventilation, allowing heat to dissipate through the ridge vent in hot weather while acting as an insulating layer when it is cold. Metal roofs can result in as much as a 30 percent reduction in heat gain through the vented roof. • Metal roofs provide the optimal foundation for photovoltaic installations since the roof can be expected to last longer than the PV system it supports. • Wall and roof solar heat recovery systems can be integrated with steel cladding and used to provide air, water or process heating needs. • Cool metal roofing is available unpainted, with thermosetting coil-applied paint finishes, or with granular-coated surfaces. This family of roofing can achieve solar reflectance of over 70 percent, meeting the EPA Energy Star Roof Products Program performance criteria. • Emittance as high as 90 percent can be achieved for painted and granular-coated metal roofing. • Painted metal roofs retain 95 percent of their initial reflectance and emittance over time. They resist the growth of organic matter and shed dirt more readily than other materials. • Cool metal roofing can help to mitigate the Urban Heat Island Effect because of its high reflectance, which can reduce ambient air temperatures. Cool metal roofs are cost-effective. • Metal roofing has low life-cycle costs, making it the choice of many school, government, commercial, industrial and institutional building owners. • Due to its light weight per unit area, structural savings can be realized in a building when compared with heavier non-metal roofing alternatives. • For re-roofing projects, metal roofing can often be applied over the original roof, saving removal and disposal costs. • Metal roofing is fully recyclable when ultimately removed as part of building renovation or demolition, allowing it to credibly claim both recycled content and 100 percent recyclability by recognized definitions. The product’s recyclability also provides significant savings on construction removal and disposal costs.
Position Paper on Oil-Canning: Specifying Wide Flat Panels in Metal Cladding
Trimet Building Products
What is Oil-Canning? Oil-canning is associated with all thin sheet metal products and occurs in the wide flat portions of the cladding profile. It is seen as a series of standing waves, or regular bumps and hollows alternating along the flat length of the panel. This waviness, when viewed under certain conditions, can be undesirable aesthetically and may not meet with the owner’s expectations. The CSSBI wants to help avoid this situation. The cladding manufacturers are aware of the potential for oil-canning in the cladding profiles and can help minimize the effect. It is important for the proper steps to be taken during manufacturing and installation to produce a quality finished product; therefore, specifiers should insist on product from a reliable, experienced cladding manufacturer, like a CSSBI member company. Quality control, however, cannot end on the shop floor. The building project needs the cooperation and knowledge of everyone involved to enhance the quality of the finished job. Oil-canning is a phenomenon that can be managed if the following factors are considered at the beginning of a project.
Repainting Factory Prefinished Metal Panels
Trimet Building Products
Introduction Prefinished sheet steel is used on many building products from wall cladding, to architectural roofing to interior panels. Prefinished sheet steel has been used in Canada for over 30 years and there may be sites were the paint surface is in need of repainting. This bulletin is intended to give some guidance on repainting prefinished panels. Due to the diversity of factory applied prefinished systems, and the diversity of potential field applied repaint systems, it is impossible to offer one comprehensive repaint procedure for all possible situations. However, it is possible to offer a set of guidelines to be considered in every potential situation.
Cool Metal Roofing -Questionable Value in Cold Canadian Climates
Trimet Building Products
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 adding insulation under the roof surface can reduce cooling and heating costs, 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 sustainable, energy efficient, coated steel products, in a wide variety of finishes, colours, textures and roofing profiles. It conserves energy through its properties of reflectivity and emissivity

SAFTI FIRST
There is a growing trend in office space design that favors increased opportunities for connectivity and collaboration among its occupants. In buildings with multiple floors, this can be a challenge as the vertical separation between floors makes face-to-face encounters less likely to happen. One way to get around this is by incorporating an atrium. See how fire rated glass helped the designers meet the fire rated requirements for this atrium while providing clear, unobstructed views.
CSSBI SSF 33-11: Wet Storage Staining of Galvanized and Galvannealed Steel Sheet
Trimet Building Products
Introduction Most cold formed steel building products, whether painted or unpainted, are manufactured from a sheet steel material that has some form of metallic coating applied. This metallic coating can be zinc (galvanized), zinc-iron alloy (galvanneal) or a 55% aluminum-zinc alloy (GalvalumeTM). The metallic coating is available in a range of thicknesses to provide the degree of corrosion protection and service life required. One of the concerns expressed by installers relates to the presence of wet storage staining on the products, how this staining impacts the long term performance, and what can be done to remove it. The purpose of this fact sheet is to address some of these issues, allay some fears, and give guidance on proper storage techniques.

Prepainted Sheet Steel: Taking on Canada’s Climate for Decades
Trimet Building Products
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
Care and Maintenance of Prefinished Sheet Steel Building Products
Trimet Building Products
Introduction Prefinished sheet steel building products, such as wall and roof cladding, liner sheet, flashing, and associated items, have experienced an enviable growth record during the past twenty years or so. Coil coated prefinished sheet steel in a variety of colours and paint systems has greatly enhanced the appearance of thousands of industrial, commercial, institutional, recreational, residential and farm buildings, providing an economical, durable and attractive alternative to traditional materials. As with all materials, a little care and maintenance pays off handsomely in terms of longevity and repair costs. The recommendations which follow have been learned at first hand and represent the collective industry experience with thin-film paint systems applied to metallic coated sheet steel by the coil coating process. In this publication the term “thin-film paint system” refers to a modified silicone polyester or a fluorocarbon type having a coating thickness about 25µm. When the guidelines listed below have been observed, thin-film paint systems have been used successfully for all types of environments other than severe industrial atmospheres which require special consideration. The guidelines are not intended for barrier coatings, laminates, and new formulations which have different characteristics than the thin-film paint systems on which these guidelines are predicated.

Fire Rated Glass Provides Privacy, Daylight at Ridgewood High
SAFTI FIRST
For a recent renovation of a stairwell and exit corridors at Ridgewood High School in Illinois, the design team specified SuperLite® II-XL 60 in GPX® Architectural Series Framing for its optical clarity, storefront-like appearance, and high STC ratings. In order to meet the code requirements and maximize the daylight penetrating into the building, the architects decided to use fire rated glass in the one-hour exit corridor. Because the glazing exceeds 25% of the wall area, fire resistive glass and framing assemblies rated equal to the wall had to be used.
Chicago Starbucks Reserve Turns Stair-Climbing Into Unforgettable Experience Using Fire Rated Glass
SAFTI FIRST
The Starbucks Reserve Roastery in Chicago features an incredible, 4-story mural by local artist Eulojio Ortega. The mural, brilliant for conveying the story as visitors go from floor to floor, is interestingly located in an exit stairwell. Traditionally, stairwells are enclosed in opaque walls, leaving them dark, isolated, and rarely utilized unless in an emergency. To allow the mural to be visible through multiple floors, encourage stair usage and meet fire rated code requirements, the architects redesigned the 2- hour stairwell using transparent, floor-to-ceiling butt-glazed glass walls with the largest tested and listed fire resistive glass panels available.
