Designing a beam for an actual structure that will support anything more than a dog (as opposed to actual human beings) as well as it's placement and connection with other parts of the structure is very critical. Therefore you should probably go to college and become licensed and certified before building something that would kill or harm people if it collapsed. As far as actually manufacturing a beam at home, dream on. The process is so complicated that nowadays they have computers that keep track of the ingredients in the metal "recipe." Also smelting requires tons of ore and large machines to process it. Burning coal produces extreme heat and pollution. Not only would your neighbors pitch a fit if you tried to start a back yard steel mill but the Environmental Protection Agency would probably knock on your door along with a bunch of other state and federal officials. Lastly, try to elaborate more on your questions. That way we know exactly what you want to know. I did way too much guessing to answer this question. Good Luck!

Depending on the application, the various loads and code considerations, it requires a good deal of knowledge and experience to be sure all bases are covered.
This is not the place to try to learn to design a beam. You should be some serious help.

Normally it is based on theory of simple bending, ie
E/R = M/I = f/y
consider last two ie M/I = f/y
M: Bending moment
I: Moment of inertia
f: Stress in steel
y: distance from extreme fibre
Choose trial section from steel table(I, Channel etc) considering stiffness requirements.
Calculate loads, effective span, Bending moment, section modulus etc.,
Check whether ur chosen section fulfils the required section modulus and radius of gyration. if it is ok, design is over. Otherwise choose a bigger section and repeat the process.
Sometimes you may need a compound section section ie combination of rolled steel section(s) with additional flange plate(s) etc to meet the requirements of section modulus, area etc.
procedure of sesining a flextural members ie a simple beam or compound beam or plate girder is similar only.
anyway u have to follow the guidelines/ standards provided by ur country.

Poor molten stainless steel in a shape.
If you don't use STAINLESS steel, you will get concrete rot and the building will decrease it's strength.

Ummm, make it an "I" other than that, elaborate
