6 We also design and fabricate the Murox high performance building system and Econox foldaway portable buildings. Canam offers customers value-added engineering and drafting support, architectural flexibility and customized solutions and services. Another Canam solution, the BuildMaster approach, has redefined the way in which buildings are designed and built by offering a safer, faster and greener process that can reduce field erection time by between 15% and 25%. Factors such as product quality, worksite supervision and construction time are critical in the execution of any project, big or small, and Canam 's reputation for reliability simplifies these considerations for customers.

7 In addition to a rigorous jobsite management process that is specifically designed to ensure that deadlines are met, our cutting-edge equipment, skilled employees and high quality products are also key in allowing Canam to keep its promises. Whatever your project, we will meet your requirements while also complying with all applicable building codes. Another aspect of our exceptional service is just-in-time delivery as per customer specifications. To eliminate delays, components are transported by our very own fleet, which stands ready to ensure on-time delivery, regardless of the location.

8 Depending on the region and worksite, Canam can transport components measuring up to 16 ft. ( m) wide and 120 ft. ( m) long. Canam is one of the largest steel Joist fabricators in North America.

All comments and suggestions for improvements to this publication are greatly appreciated and will receive full consideration in future , services and solutionsTHE ADVANTAGES OF USING STEEL JOISTSU sing a steel Joist and steel deck system for floor and roof construction has proven itself to be a most advantageous solution. It can result in substantial savings based on: Efficiences of high-strength steel; Speed and ease of erection; Low self-weight of roof and floor construction allowing for smaller columns and foundations than for a concrete structure; Increased bay dimensions, which reduces the number of Joists and columns and simplifies building erection; Greater floor plan layout flexibility for the building occupant due to the increased bay dimensions.

10 Maximum ceiling height due to installation of ducts through the Joist web system; Easy adaptation to acoustical insulation systems; Floor and roof composition having long-term resistance to fire, as established by the Underwriters Laboratories of Canada (ULC).DESCRIPTION OF A Joist GIRDERDEFINITIONA Joist girder is a primary structural component of a building. Generally, it supports floor or roof Joists in simple span conditions, or other secondary elements (purlins, wood trusses, etc.) evenly spaced along the length of the Joist girder.
