    I found https://spanman.net/
    A calculator for Australian Building code span loads!

    My question:

    When you use Purlin Single Span to Calculate C Section.
    https://spanman.net/Members/purlin-single-span

    I choose Country Australia, Building type Garage.
    Span 4220mm, Spacing 1000mm.
    Roof Custom Setting 33kg/m2.
    Ceiling (none).
    Design Material = Cold Formed / Light C Section.


    The results are returned for using C Section using minimum material with:
    1 Row Bridging.
    Or,
    2 Rows Bridging.
    Or,
    Just the C Section size without bridging.

    ------

    SOLUTIONS
    Name ___________- kg/m - Depth (mm)
    C10015 2 rows bridging 2.6 102
    C15012 1 row bridging 2.9 152
    C10019 2 rows bridging 3.3 102
    C15015 1 row bridging 3.6 152
    C20015 1 row bridging 4.5 203
    C15019 1 row bridging 4.5 152
    C15024 1 row bridging 5.7 152
    C20019 1 row bridging 5.7 203
    C25019 ___________6.5 254
    C20024 1 row bridging 7.2 203
    C25024 ___________8.2 254
    C30024 ___________10.1 300
    C30030 ___________12.8 300
    C35030 ___________15.2 350
    ------


    I am assuming the C Section recommendations with no bridging can support load independently?

    What do they mean by 1 or 2 row bridging?
