I believe they are cast.

I don't know what your'e calling a "T-post" but if you have a picture of it in your minds eye... does it have a parting line down the body?? Or do you see little kind of inverse sand grains on the surface? If you do its a cast part. If what you see is a continuous cross section, with little or no variation it will be a hot or cold rolled part. I've seen this in the various steel books and what the steel companies will do for you is cut an 'I-beam' thru the web and give you half of it as a "T-beam'. Hope that gets you where your going!

Not sure what you mean by t-post.
But if you mean a vertical post with a horizontal member attached to the top, making a "T" shape, just because you see no seam and it looks like it is made of one part doesn't mean it is. "T" shapes like this are usually welded together, they can look like one piece if the weld is ground smooth. Depending on the finish of the base material, welds can be ground and polished to blend almost perfectly and reveal absolutely no seam to the naked eye.

The general shape is extruded through a die, then finished and cut to size.
