CSA G40.20-04 - General requirements for rolled or welded structural quality steel/ Structural quality steel

Scope
This Standard outlines the requirements that apply, unless otherwise specified in a purchase order or individual standard, to structural quality steel plates, shapes, sheet, sheet piling, cold-formed channels, hollow sections, Z sections, and bars conforming to the requirements of CSA G40.21.

Tables 11(a) to (h) of CSA G40.21 provide information on the dimensions and mass (weight) per unit length of structural shapes and sections commonly used in the construction of steel buildings and bridges.

In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.

The values stated in either SI (metric) or yard/pound units are to be regarded as standard. Within the text, the yard/pound units are shown in parentheses. The values stated in each system are not exact equivalents; each system must be used independently. Combining values from the two systems can result in nonconformance with this Standard.
