Cold-Formed Steel Codes and Standards


This wiki (editable page) was created so that a large group of people could contribute to developing a list of the cold-formed steel codes and standards that are in use around the world. To aid in the development of this list Ben Schafer (schafer@jhu.edu) sent an initial email to members of the following organizations: CFSEI, SSRC TG 13, ASCE-SEI CFS, AISI-COS, AISI-COFS.


Help us now!

See how easy it is to add (or correct) the standards of your own country

1. Click "Edit Page" at the top of this page (enter the password, contact schafer@jhu.edu if you do not have it)

2. Add information about your country or a country or region you know (add your name to the bottom as a contributor)

3. Click Save!


Please add information about any country that you know information about the current cold-formed steel specifications in use below. The following divisions for countries is based on http://en.wikipedia.org/wiki/List_of_countries, any such division is flawed to begin with, but provides a means to organize the results. Feel free to add any notes you would like as well. Some countires which are listed below were of particular interest to the initial group forming this list. Your help is much appreciated.



Specification: Unknown

Building Code: Unknown



United States

Specification: North American Specification for the Design of Cold-Formed Steel Structural Members. American Iron and Steel Institute (http://tinyurl.com/yq5wzo) latest version now numbered as AISI-S100-07, 2007 version nearing final approval as of June 2007.

Building Code: International Building Code, International Code Council (http://www.iccsafe.org/) local building codes and/or NFPA may also be enforced, but the IBC is as close to a national building code as exists in the United States, both IBC and NFPA reference AISI.


Specification: S136, full details needed

Building Code: National Building Code of Canada, full details needed

Puerto Rico

Specification: Unknown

Building Code: Unknown
