ASTM WK43177

    Revision of C645 - 13 Standard Specification for Nonstructural Steel Framing Members

    (What is a Work Item?)

    Active Standard: C645 - 14

    Developed by Subcommittee: C11.02 | Committee C11 | Contact Staff Manager


    1. Rationale

    Paragraph 4.2 requires an update. Currently, only one type of coating A653/A653- G40 is listed. To be more comprehensive, a new table similar to the table 1 of C955 is needed. The proposed table will be more comprehensive and will include all coatings listed in Table 1 of A1003 for NS steel. The ambiguous equivalent corrosion resistant is deleted and replaced with said table for clarity. Other appropriate coatings may be added when fully vented by A05 committee and listed in Table 1 of A1003.
