A W8x35 steel I-beam, which is 8 inches in depth and weighs 35 pounds per foot, weighs approximately 35 pounds for each foot of length. Therefore, a 22-foot-long W8x35 I-beam would weigh about 770 pounds (35 pounds/foot × 22 feet).

If it is not coated, it is exposed to the air (or whatever) and will rust.

It isn't so much a machine. It is a method. It is used to make iron into steel. Iron has impurities and Bessemer found out that if you pump air into the iron it removes the impurities and it becomes steel.
The steel reinforcement used will depend on several factors. Column length, beam length, and the column and beam cross section all depend on how much steel will be needed.
Beam bridges cost about 1 billion dollars to make.
The density of a substance stays the same, no matter how much space it takes up.
cost of steel 12''x18' i-beam per linear foot?
Depends, of course, on the density of the steel.
The weight of a 6x6x10 beam will depend on the type of material it's made of (e.g., wood, steel, aluminum). Typically, a wooden beam of these dimensions would weigh approximately 84 pounds. It's best to refer to specific material weight charts or consult with a supplier to get an accurate weight for the specific type of beam you are using.
A steel plate of that size would weigh approximately 368 pounds.
If it is 20 gage steel it would weigh about 450 pounds

Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
That depends on how heavy it is. Steel beams are measured by height and width and weight-per-length As an example A beam you describe as measured in the UK could be 200mm X 100mm X 30kg/m 12 feet is approx 4m so total beam weight 120kg. This is just an example and it all depends on the unit weight. If you measure the thickness of the steel then look up steel tables online you should get a pretty good idea.
