Why build a Steel Mast?
I will awnser that question with a question. Why build a steel boat, you could just go out and buy one. Maybe at a really good price. Why buy a steel boat when you can buy a fiberglass boat? Why do anything?
You build the mast for the same reason you build the boat. Whatever reason they may or may not be. I build the mast for my steel boat, 'Notion' to save a little money. I had more time than money, and I could build the mast.
Whatever you reasons, here is the place to learn how to do it from someone who has done it.
Steel Mast Sections:
There are a number of section shapes that can be considered for a fabricated steel mast: Oval, Rectangular with radius corners, Multi-sided, and Round. All the sections are formed from sheet material and formed in a Press-brake with the exception of a Round section. All the hardware attached to the mast can be fabricated including: Mast Head, Spreaders, and Stay attachments to name a few.

Steel Mast Design:
To illustrate the practically of steel as a mast material, I will be calculating the dimensions of a mast for a 34-foot steel sailboat in steel, aluminum, and wood. The design results will than be compared to aluminum and wood designs. The formulas that I will be using are:
Euler's - Slender Column Formula
USYRR (United States Yacht Racing Rules)
