CSA - G40.20-04/G40.21-04

General requirements for rolled or welded structural quality steel/ Structural quality steel

inactive
Organization: CSA
Publication Date: 1 February 2004
Status: inactive
Page Count: 110
scope:

This is the sixth edition of CSA G40.20/G40.21, General requirements for rolled or welded structural quality steel/Structural quality steel. It supersedes previous editions published in 1998, 1992, 1987, 1981, and 1978.

This edition comprises amendments published in General Instruction No. 2 to the previous edition, corrections of errata, and new amendments approved by the Technical Committee on Structural Steel. These include

(a) a change in the location of tensile test samples from the web to the flange on W, HP, S, and M shapes;

(b) the adoption of CAN/CSA-G40.23 for assessment of the surface quality of plate;

(c) the acceptance under G40.20/G40.21 of products manufactured in conformance with ASTM A 992/A 992M, Structural Steel Shapes;

(d) the addition of requirements for cold-formed Z sections;

(e) revisions to the permissible variations in the dimensions of cold-formed channels; and

(f) the addition of Table 11, which provides the dimensions and mass (weight) of commonly available structural shapes and hollow structural sections, replacing and updating information in CAN/CSA-G312.3-M, Metric Dimensions for Structural Steel Shapes and Hollow Structural Sections (withdrawn in 2001).

These Standards are written in SI (metric) units, with yard/pound units included in parentheses. The SI units are in conformance with CSA Z234.1, Metric Practice Guide.

While the technical requirements of the metric and yard/pound versions are virtually the same, some differences do occur. Either the SI or the yard/pound units must be used, and any attempt to intermingle the two systems of units on any specific purchase of material may result in nonconformance with the Standards.

These Standards have been harmonized to the maximum possible extent with equivalent ASTM Standards A 6/A 6M and A 568/A 568M.

These Standards were prepared by the Technical Committee on Structural Steel, under the jurisdiction of the Strategic Steering Committee on Welding and Structural Metals, and have been formally approved by the Technical Committee.

February 2004

Notes:

(1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization - Code of good practice for standardization as "substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity". It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.

(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.

(5) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.

Requests for interpretation should

(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

(b) provide an explanation of circumstances surrounding the actual field condition; and

(c) be phrased where possible to permit a specific "yes" or "no" answer.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSA's periodical Info Update, which is available on the CSA Web site at www.csa.ca.
