Lindmark Steel

Lindmark Steel is a billboard fabrication, installation, and service and repair provider operating as an integral division of The Lindmark Companies, the vertically integrated outdoor advertising group that also includes Lindmark Billboards and Lindmark Ink. Based in Euless, Texas, Lindmark Steel was formed when Lindmark acquired the long-established Sign Erection, Ltd. operation, commonly known as SignCo or Woody's Sign Company, from Woody Barnes in 2023, bringing decades of fabrication heritage under the Lindmark banner. The business carries a lineage of sign and billboard fabrication reaching back to the mid-1960s and reports more than 10,500 structures built over that history.

Within the OOH ecosystem, Lindmark Steel handles the physical backbone of billboards: engineered steel structures, foundation-to-final-assembly installation, and ongoing service and repair. Its capabilities include high-rise monopoles and specialty gas-can style signs, digital conversions that retrofit static structures for LED displays with structural assessments and reinforcement, and removal and relocation work involving disassembly, transport, and reinstallation for DOT and municipal projects. The company positions itself as a premier billboard fabricator and installer in the southwest, serving operators across Texas, Oklahoma, New Mexico, Louisiana, Arkansas, and Kansas, and it also delivers structures to operators nationwide.

By pairing steel fabrication with installation and maintenance under one family-led roof, Lindmark Steel gives billboard operators a single source for building, converting, and maintaining outdoor advertising structures at scale.
