This European Standard EN 1993-1-3, Eurocode 3: Design of steel structures: Part 1-3 General rules - Supplementary rules for cold formed members and sheeting, has been prepared by Technical Committee CEN/TC250 " Structural Eurocodes ", the Secretariat of which is held by BSI. CEN/TC250 is responsible for all Structural Eurocodes.
This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by April 2007, and conflicting National Standards shall be withdrawn at latest by March 2010.
This Eurocode supersedes ENV 1993-1-3.
According to the CEN-CENELEC Internal Regulations, the National Standard Organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
National annex for EN 1993-1-3
This standard gives alternative procedures, values and recommendations for classes with notes indicating where national choices may have to be made. Therefore the National Standard implementing EN 1993-1-3 should have a National Annex containing all Nationally Determined Parameters to be used for the design of steel structures to be constructed in the relevant country.
National choice is allowed in EN 1993-1 -3 through clauses:

EUROCODE 3 - DESIGN OF STEEL STRUCTURESPart 1-3: General rules. Supplementary rules for cold-formed members and sheeting
1.1 Scope
(1) EN 1993-1-3 gives design requirements for cold-formed thin gauge members and sheeting. It applies to cold-formed steel products made from coated or uncoated thin gauge hot or cold rolled sheet or strip, that have been cold-formed by such processes as cold-rolled forming or press-braking. It may also be used for the design of profiled steel sheeting for composite steel and concrete slabs at the construction stage, see EN 1994. The execution of steel structures made of cold-formed thin gauge members and sheeting is covered in EN 1090.
NOTE: The rules in this part complement the rules in other parts of EN 1993-1.
(2) Methods are also given for stressed-skin design using steel sheeting as a structural diaphragm.
(3) This part does not apply to cold-formed circular and rectangular structural hollow sections supplied to EN 10219, for which reference should be made to EN 1993-1-1 and EN 1993-1-8.
(4) EN 1993-1 -3 gives methods for design by calculation and for design assisted by testing. The methods for design by calculation apply only within stated ranges of material properties and (5) EN 1993-1-3 (6) 1.2 EN 1993 EN 10002 EN 10025-1 EN 10025-2 EN 10025-3 EN 10025-4 geometrical proportions for which sufficient experience and test evidence is available. These limitations do not apply to design assisted by testing.
(5) EN 1993-1-3 does not cover load arrangement for testing for loads during execution and maintenance.
(6) The calculation rules given in this standard are only valid if the tolerances of the cold formed members comply with EN 1090-2.
1.2 Normative references
