What Architects and Preservation Specialists Need

Pressed metal ceilings were among the defining architectural features of American commercial and civic buildings from the 1880s through the 1930s. Hotels, courthouses, theaters, schools, and saloons installed them by the thousands; not merely as decoration, but as practical solutions that offered fire resistance, dimensional detail, and affordability at a time when ornate plaster was the only alternative.

 

Many of those ceilings survive today, and the architects, preservation specialists, and developers responsible for them face specific challenges that generic ceiling suppliers are not equipped to address.

 

Shanko has been manufacturing authentic pressed metal (historically “tin tiles”) ceiling tiles since 1896. We are the only American manufacturer still producing from the original hand-carved steel dies used at the height of the tin ceiling era. That continuity is not a marketing point; it is the foundation of what makes Shanko the right partner for restoration work. When you specify Shanko, you are specifying patterns pressed from the actual embossing plates that may have produced the ceiling you are restoring.

The Restoration Challenge Is Different

Standard ceiling replacement is straightforward. Historic restoration is not. Preservation boards, State Historic Preservation Officers, and the National Park Service all have specific standards governing the replacement of historic materials. The Secretary of the Interior's Standards for Rehabilitation define what constitutes an acceptable treatment, and in the case of pressed metal ceilings, authenticity is the threshold question. A reproduction that looks similar is rarely sufficient. Pattern depth, relief detail, gauge, and material type all factor into preservation approvals—especially in historic public buildings such as Churches, Schools, and Courthouses, where architectural integrity and historical accuracy are critical to meeting preservation guidelines.

 

Beyond regulatory compliance, restoration architects face practical constraints that require a supplier with real manufacturing depth. Mid-project material needs, color lot consistency, pattern documentation, and the ability to match an obscure period design from a sample tile are all routine requests in restoration work. Shanko's production capabilities and our original die library are built for exactly these situations.

Who This Section Is For

The pages in this section are written for the professionals who bear responsibility for getting restoration projects right:

Architects working with preservation boards

Ensuring material authenticity and compliance with SHPO and NPS standards.

Contractors managing historic public building renovations

Balancing documentation, scheduling, and material consistency mid-project.

Developers navigating Historic Tax Credit applications

Protecting Part 2 approvals through accurate material specification.

Building owners trying to understand what authentic replacement actually means and why it matters.

Understanding what authentic replacement means and why it matters.

We cover the regulatory framework you need to understand, the process of identifying and matching original patterns, the specific challenges of public building restorations, and the financial case for authentic materials when federal tax credits are in play. Each section is designed to give you the information you need to make decisions and write specifications, not to sell you on tin ceilings in general.

Why the Original Dies Matter

Most manufacturers producing historically-styled metal ceiling tiles today work from molds made after the fact, either cast from surviving original tiles or designed from photographic references. The difference in the finished product is visible. Original dies produce sharper relief, deeper embossing, and crisper edge definition than second-generation reproductions. For preservation work, this distinction often determines whether a submission passes muster with a State Historic Preservation Officer.

 

Shanko's dies have been in continuous production for over a century. We have never digitized them or replaced them with CNC-produced parts. Every panel we press carries the same depth and detail that architects specified when these buildings were first constructed.

What You Will Find Here


This section covers five areas essential to historic restoration work.


 

  • Churches, schools, and courthouses present unique restoration challenges that we address specifically.

  • We walk through the Secretary of the Interior's Standards as they apply to pressed metal ceilings and explain what documentation preservation boards typically require.

  • We provide a practical guide to identifying original patterns and finding accurate matches.

  • And we lay out how material authenticity affects Historic Tax Credit eligibility, including what the IRS and NPS look for in a Part 2 certification.

  • We give you some examples of our previous historic restoration work.


If you are working on a historic restoration project involving pressed metal ceilings and want to discuss specifications, samples, or documentation support, contact Shanko directly. We have worked with preservation architects and building owners across the country and understand what these projects require.
