Changing standard thicknesses for Canadian lightweight steel framing applications

Starting in june 2004, Canada and the United States will both have a common set of standard base steel thicknesses for lightweight steel framing components (e.g. studs and joists). The North American cold formed steel industry has been pursuing the benefits of standardization, by harmonizing both framing products as well as engineering design practice. The North American Specification for the Design of Cold-Formed Steel Structural Members ( the CSA-S136-01 standard in Canada) is the current design document for cold formed steel structural members, and is the first North American structural design standard. This one document applies in Canada, United States and Mexico. With the further adoption of common thicknesses, the manucfacturers of lighweight steel framing products in North American can work towards standardizing product geometries that will also benefit the construction industry. The new standard thicknesses are provided in Table 1 shown below.
