HSS with holes
HSS with holes
(OP)
I'm designing a steel framed canopy with HSS 10x10x1/4 columns. The architect wants electrical recepticles recessed into the columns, so the column will have a 4"x4" square hole in one side. I've never come across this situation. I've always seen stuff surface mounted.
What is the failure mode of this column at such a large hole?

A bigger concern, as these are external columns, would be corrosion. I would want them to be hot dipped galvanized to protect the inside of the columns.

All structural steel is supposed to be powder coated after fabrication (i.e. after the holes are cut). What is it with architects and powder coating anyway? They love this stuff.
RE: HSS with holes
Powder coating will not protect the steel, particularly inside. Galvanize it first, then powder coat. However, the galvanizing may not give a smooth enough finish for the architect, but then some like it rough. You can never second guess an architect.

I thought about having them drill 1/4" holes at the corners. Thanks for validating that.
