Dear Keith:

As we discussed on November 5, 1999, with considerable personal regret, I
officially resign from the Board of Directors of Steel Dynamics, Inc. effective
immediately. It has been my pleasure to serve on the board and to work with you
and the rest of your team over the past several years.

Notwithstanding my resignation, GE Capital obviously remains an interested
investor in SDI and appreciate our ongoing relationship. Accordingly, if there
is anything we can do for you, financially or otherwise, please give me a call.

Good luck to you and the Company in your endeavors.


                                                    Very truly yours,


                                                    /s/ William D. Strittmatter
