    Default Metal Deck Supports

    Can metal supports that are exposed to the elements be used for deck construction?

    If so, are the ones in the pictures the proper type? They look like temporary supports to me but there was no info on them. They are fastened at the bottom with too small of a bolt also.

    This is what the NC code says about columns. Those post in the pictures look like the temporary-use post that the big box stores sell. They are made of lightweight steel and are too small in diameter.

    R407.1 Wood column protection. Wood columns shall be
    protected against decay as set forth in Section R319.
    R407.2 Steel column protection. All surfaces (inside and outside)
    of steel columns shall be given a shop coat of
    rust-inhibitive paint, except for corrosion-resistant steel and
    steel treated with coatings to provide corrosion resistance.
    R407.3 Structural requirements. The columns shall be
    restrained to prevent lateral displacement at the top and bottom
    ends. Wood columns shall not be less in nominal size than 4
    inches by 4 inches (102 mm by 102 mm) and steel columns
    shall not be less than 3-inch-diameter (76 mm) standard pipe or
    approved equivalent.
    Exception: In Seismic Design Categories A, Band C columns
    no more than 48 inches (1219 mm) in height on a pier
    or footing are exempt from the bottom end lateral displacement
    requirement within underfloor areas enclosed by a
    continuous foundation.

    They do not appear to have any footers and were secured with some very small rusty bolts.
