Steel Column for Wood Framed balcony (V-A)

[admiralArchArch]

2018 IBC, Type V-A construction, R-2.
I have some corner balconies that we are using a steel column to support the corner.
At first I thought I may have to apply fire-proofing to the column per table 601, but IBC 705.2.3.1 exception 3 states balconies of Type V construction "shall be permitted to be of Type V construction and shall not be required to have a fire-resistance rating where sprinkler protection is extended to these areas". We will have spinkler protection at balconies.

Is it correct to interrupt that that exception extends to the steel column as well?

Yes, that is correct, if there is an exception that would allow a wood column to be unprotected in a sprinklered Type V building, the exception also applies if you replaced that wood column with a steel column.

You can use metal in a Type V building per…

2021 IBC 602.5 Type V (emphasis added)
Type V construction is that type of construction in which the structural elements, exterior walls and interior walls are of any materials permitted by this code.

602.1.1 Minimum Requirements (emphasis added)
A building or portion thereof shall not be required to conform to the details of a type of construction higher than that type which meets the minimum requirements based on occupancy even though certain features of such a building actually conform to a higher type of construction.
