Start at the foundation where the loads imposed by a steel frame are up to 50% less than those of a concrete alternative. There is evidence in the field and through third-party case studies and comparative cost studies that steel building systems offer significant cost benefits over competitive building materials when the total cost of construction is considered.

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

Executive Summary The aim of this fact sheet is to advocate an alternative solution for the Steel Industry in regards to restrictive code provisions for explosion venting that are now mandated by the Ontario Fire Code (OFC). Due to a September 2000 amendment of code provisions dealing with explosion venting in the OFC, explosion vent designs were required to be in conformance with NFPA 68, the National Fire Protection Association’s (NFPA) Guide for Venting of Deflagrations. NFPA 68 gives a prescriptive solution that has upper bound limits on size and mass of an explosion vent panel, which the Steel Industry finds are too small to be practical. The Canadian Steel Construction Council (CSCC) investigated this problem and identified an alternate design guideline from the Factory Mutual Insurance Company’s (FM) Property Loss Prevention Data Sheets, numbered 1-44 and entitled “Damage Limiting Construction”. FM’s 1-44 Data Sheets can be used to develop an alternate solution for explosion venting that exceed the size and mass limits of the NFPA 68 prescriptive solution, and can be submitted for approval under the Compliance Equivalency provisions in the OFC. With the introduction of an objective based National Building Code Canada (NBCC) in 2005 followed by Provincial code adoptions in 2006 it would be worthwhile to establish a precedent through the Compliance Equivalency provision in the OFC. Once a precedent setting case occurs, the “acceptable solution” or “compliance alternative” would go on record and aid in resolving subsequent proposals for Compliance Equivalency, and also support a future technical change in the OFC. The CSCC by way of this fact sheet would advocate this alternative solution for the Steel Industry when designing explosion vent panels in steel framed buildings.

One of the most common questions asked by homeowners about the installation of their steel roof is whether an underlayment is needed. The answer to this question is “yes” in most situations. The underlayment plays a critical role in controlling the migration of condensation that might develop on the underside of the steel sheet thereby preventing accumulated water entering the building resulting in costly damage.

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. 

An independent assessment of the life cycle cost for various low slope roof systems revealed that steel roofing had the longest life span, no leaks due to material failures, and the lowest overall maintenance cost.

During construction of a luxury automotive dealership, MAPEI products were used for surface preparation, waterproofing, uncoupling protection, and tile and stone installation. High moisture content and a fast-approaching deadline were no match for these products, which produced award-winning results.

“We Were Looking for a Product That Would Seamlessly Transform an Indoor Living Space into an Outdoor Space, Yet Still Provide Strong Assurances Against Wind and Rain.”

A variety of setting materials and innovative sound-reduction products from MAPEI were all part of completing a new-build complex of luxury residences and a four-star Marriott hotel on Lake Ontario’s north shore.

Faced with a tight schedule and challenging weather conditions, Belluz Group Ltd. turned to MAPEI for the range of high-end products and support that was needed to complete a new-build terminal project in the heart of Canada’s biggest city.
