Upon its purchase from Woody Barnes in 2023, SignCo a/k/a Sign Company in Fort Worth, Texas became "Lindmark Steel", an integral division of The Lindmark Companies. Lindmark Steel continues the rich tradition of SignCo in its fabrication and construction of the highest quality off-premises signs.

Since the mid 1960's, Woody has been fabricating, erecting, and installing signs, beginning with on-premises signs then shifting exclusively to off-premises signs. Woody estimates that he has built more than 10,500 (and counting) signs in his career. When Woody started talking more and more seriously about retirement, Lindmark couldn't let Woody's, and his highly skilled employees', immense knowledge, expertise, and experience simply fade away, which led to the purchase of SignCo, now Lindmark Steel, and the appointment of Woody to the position of Director of Organic Growth with The Lindmark Companies where Woody is able to mentor and impart his wisdom to the employees of Lindmark Steel and Lindmark Billboards.

Lindmark Steel is focused on meeting the serious demands Lindmark Billboards placed on it due to the hundreds of billboard sites Lindmark Billboards' Organic Growth Team perpetually identifies and secures. By vertically integrating sign fabrication and construction, The Lindmark Companies is now able to solidify and expand its markets at a faster rate while maintaining its highest of quality standards.
