I'd like to build porch railings as a first ornamental iron project. King
Archetectural Metals has a great selection of materials. I'm looking for
suggestions on what material type is a good choice for this project.

For example, should 1 " posts be solid or square tubing? If I use tubing,
the choices are 16 ga (O&P), 14 ga (P&O) and 11 ga plain hot rolled. Any
suggestions would be appreciated.

Thanks,
-Tom
