You need to provide more information - length and diameter or dimensions across flats of the post. I can then tell you roughly what it will be.

It is a self drilling, self tapping screw for steel to steel applications. For wood to steel applications, there are reamer tek screws available.
Yes, a diamond-tipped tool can cut through steel.
For surface area of steel bar= pi*diameter*length For cross-sectional area of steel bar= pi (dia)^2/4
without touching it? no what you will have to do is sand or scrape the pipe then you will be able to tell the difference. if its a dull metal then its black iron but if it shines then it would be galvanized.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
density of galvanized steel 7850kg/m3
Galvanized steel sheet is basically indistinguishable from zinc steel. If you want to buy galvanized steel sheets. You can go to Shanghai Changzheng, which is the choice of most people for its superior quality steel sheets.
Answer These are different descriptions for a part. Tubular Steel describes the shape. Steel can be ordered in different sizes and shapes and material properties. Tubular Steel is one type of shape and the process for making the tube will cause the properties for that steel to be slightly different. Galvanized Steel describes a type of finish that protects the steel from corrosion. This process alters the surface of the steel that keeps it protected and thus can be used for construction where it is exposed to the elements. I'm sure you can order a steel tube that has a galvanized finish. Many chain-link fences are made from galvanized steel, including the round posts. Custermen
Galvanized Sheet Metal
Any plumbing supply and it comes in galvanized steel , black steel, Brass

Stairs made of Galvanized steel. It's a type of anti-rusting steel.
Yes, my welder welds galvanized steel to black steel all the time. Welding galvanized steel to black steel is a common practice. Glavanized is nothing more than steel coated with zinc at 900 degree C; temperature at which zinc melts. However, welding temperature is around 15000 to 30000 degrees ( zinc will vaporize at 1500 degrees), causing the zinc around the weld to vaporize. Correct way to approach this problem would be to use a half coupling, half nipple, or thread o let on a threaded glavanized pipe then welding the otherend to straight steel.
Yes, a magnet will stick to galvanized steel. Galvanized steel is steel that has been dipped in molten zinc so it comes out with a zinc coating. (The zinc coating inhibits corrosion.) A magnetic can "reach through" this coating and stick to the steel.
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
