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.




(Added by C. van Zandwijk M.Sc.) 

Specification: Unknown - (I visited the Ministry of Works & Urban Development in Addis Ababa but they couldn't help me with any code about Cold Formed Steel)

Building Codes

  • EBCS-1   Basis of design and actions on structures
  • EBCS-3   Design of steel structures



 South Africa


(Added by Dr Hennie de Clercq, SA Institute of Steel Construction)

Specification: SANS 10162 - The Structural Use of Steel: Part 2 - Limit-state design of cold-formed steelwork

Building code: National Building Regulations of South Africa



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 (http://www.csa-intl.org/onlinestore/GetCatalogItemDetails.asp?mat=000000000002415602)

Building Code: National Building Code of Canada (http://www.nationalcodes.ca/nbc/index_e.shtml)

Puerto Rico

Specification: Unknown

Building Code: Unknown - but the ICC has a Puerto Rico field office (http://www.iccsafe.org/government/international.html) so likely one can use ICC for the building code. If so, then this means the U.S. Spec. would be applicable for cold-formed steel.


Specification: North American Specification for the Design of Cold-Formed Steel Structural Members, full details needed

Building Code: Unknown - (some sort of arrangement with ICC in 2005, don't know what came of it)



Specification: NBR 14762:2001 Dimensionamento de estruturas de aço constituídas por perfis formados a frio - Procedimento (Cold-formed steel design - Procedure, last update 2001) and NBR 6355:2003 Perfis estruturais de aço formados a frio - Padronização (Cold-formed steel structural profiles, last update 2003)

Building Code: ABNT - Associação Brasileira de Normas Técnicas (www.abnt.org.br)


NCH 427 - suspended because it was written in the 1970's. Cold-formed steel sections were based in part on AISI (U.S). The local Institute for Building code INN has specified in recent Codes for seismic design that designers must use the last edition of the AISI Specification for cold formed steel and the AISC for hot rolled , in their original versions in english until some traduced adaption will be issued here .


CIRSOC 303 for Light Steel Structures where cold formed steel is included. That Specification, now more than 20 years old , is being replaced by a new one , which will be , in general , an adaption of the current AISI one. The former CIRSOC 303 was an adaption of the Canadian code of that time. At this time CIRSOC 303 was very old, now CIRSOC 301 is in revition to be aligned with the american codes (LRFD design). In the near future both codes will be alligned also in designations and therminology.

Specification:IS:801, Indian standard code of practice for use of cold-formed light gauge steel structural members in general building construction, Bureau of Indian Standards, New Delhi (1975). (currently under revision)

Building Code : see - model code National Building Code of India (http://www.bis.org.in/sf/nbc.htm)

Above information on India by B. Schafer from web research needs verification.


(Added by Gaoning Wang) 

Specification: Technical Code of Cold-formed Thin-wall Steel Structures

Building Code: GB 50018-2002 (current version)


Specification: Design Manual of Light-gauge Steel Structures

Building Code: Technical standard notification No.1641 concerning light-gauge steel structures


Based on informal discussion it is currently believed that no cold-formed steel Specification nor Building Code exists in Singapore, instead British Standards are in current use.


(added by C.C. Choo - 7th March 2008)

Cold formed steel design in Malaysia uses the BS5950 as the standard especially BS5950:Part 5.

Also, AS4600 (from Australia) is referenced.


(contribution from Dzulkarnain Ahmad posted by Ben Schafer)

Currently (July 2007) Malaysia uses British Standards as references. It is unknown when and if Malaysia will have their own standards. With introduction of Eurocodes in the UK it seems the Malaysian goverment will likely go towards that approach.
