    Revision of C645 - 11a 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

    Currently Section 4.2,lists only one type of coating, A653/A653M.There are several other coatings listed in Table 1 of A1003 such as A972, A875, A463, and A879 that are not included. Also,this Section allows for alternate coatings to be equivalent to G40 but does not define performance requirements of these equivalent coatings. This ballot is to eliminate ambiguous language and replace it with a table of acceptable coatings already recognized in A1003. This will make this standard clear and concise.
