EVANSVILLE, Ind. (Apr. 21, 2026) — A recent New York Times feature on the restoration of the historic revolving door at New York City’s Flatiron Building has put an Evansville manufacturer at the center of a nationally recognized preservation project.
In the April 17 article, the Times highlighted International Revolving Door Company (IRD) and its role in restoring the early-20th-century wood door at the base of the landmark building. The story details the challenge of recreating the door’s original ornate appearance without the original specifications, the intricate millwork required to match its historic design, and the restoration work completed in Indiana before the door returned to Manhattan for installation. The restored door now serves as the main residential entrance as the Flatiron Building is converted to condominiums.
Founded in 1907, International Revolving Door is recognized as one of the oldest revolving door manufacturers in the world and traces its heritage to the original revolving door patent era of the late 1800s. Headquartered in Evansville, the company specializes in custom-crafted entrance solutions including classic, all-glass, security, and large-diameter revolving doors, serving commercial buildings with products focused on durability, energy efficiency, and design excellence. With more than a century of craftsmanship and innovation, International Revolving Door continues to blend historic expertise with modern engineering.
The Flatiron project is a reminder that companies in the Evansville Region are not only producing high-quality work but also competing for and delivering on nationally visible projects. For the Evansville Region, the feature underscores the specialized craftsmanship and manufacturing capability already operating here.
E-REP’s business retention and expansion team visited International Revolving Door Company in August 2024 as part of its ongoing outreach to existing employers. During that visit, company leadership discussed growth plans, equipment investments and interest in a local property tax incentive to support expansion.
That work continued in 2025, when E-REP facilitated the incentive process tied to the company’s investment at its 2138 N. Sixth Ave. facility. The Evansville Common Council approved a five-year personal property tax phase-in for the project. The company, which employs more than 40 people, projected that the expansion would add 23 new full-time permanent jobs over five years. Nearly all of its work is installed outside Indiana, bringing business from across the country back to the Evansville Region.
