Note: Contemporary metal materials are known for their inherent immutability. While a number of metals can withstand many decades, it is important to consider how these materials are fabricated and installed, such that environmental concerns, galvanic corrosion, alloy selection, and other factors are properly considered and understood.

The long-term preservation of metal art and architecture is at the forefront of the research by CEO L. William Zahner. Through his role as chairman at Metalabs and his ongoing research and publications, Mr. Zahner hopes to promote the resilience of both immutable and transformative metals throughout the disciplines of art, sculpture, and architecture.

Restoring Art: That Profile, by Martin Puryear

That Profile is a forty-five foot sculpture by American artist Martin Puryear. The artwork rises into the air above the Tram Arrival Plaza at The Getty Center in Los Angeles, California. Installed in 1999, the stainless steel and bronze sculpture began showing signs of deterioration after a short time, which led administrators at The Getty to seek an expert in metal restoration.

The Getty contacted L. William Zahner, an expert in the field of metal sciences, to run tests on That Profile and determine how to restore and protect it for the future. His analysis revealed that the stainless steel “nodes” or joints which connect the linear aspects of the sculpture had weakened in the California weather. Mr. Zahner developed a two-stage cleaning process with a chemical wash and electropolishing process to revive the original stainless steel finish and add strength to the nodes.

Corinthian Hall

Corinthian Hall Canopy at Kansas City Museum

Originally constructed as a residence by lumber magnate R.A. Long in 1910, Corinthian Hall was donated to the Kansas City Museum Association in 1939 by Long’s two daughters. In 1948, the building was deeded to the City of Kansas City after museum funds were determined to be insufficient in maintaining the estate.

In 1996 International Architects Atelier was commissioned to conduct a restoration study and provide a preliminary cost estimate for restoration of the various estate buildings, including the main house, carriage house and stables, caretaker’s house, carpenter’s workshop, conservatory, pergola and limestone and wrought iron fence surrounding the three-acre estate.

Zahner was brought in to work on restoration of the Corinthian Hall canopy through MTS Contracting. The canopy restoration was part of a larger master plan for the historic restoration and adaptive renovation of Corinthian Hall into a mixed-use facility, incorporating elements of a traditional historic house-museum with modern elements.

Corinthian Hall’s beautifully elaborate cast bronze porté cochére canopy over the west porch was removed from its original mountings and transported to Zahner where the historic pieces were cleaned and restored with respect to its original design. Work included the re-creation of the deteriorated, original structural support system from stainless steel, re-casting and re-patination of several missing elements, and re-wiring of the original electrical service.

Using historic photographs for reference, fragments of the original glass were used to recreate the canopy glazing from a UV-stable, non-yellowing resin material, which replicates the appearance of the original glass while providing superior strength against breakage.

Midland Theatre

Arvest Bank Theatre at the Midland

Midland Theatre is a historic 3,573-seat theater located in the Power & Light District of Kansas City, Missouri. The building was originally designed by Boller Bros, and has at various states been restored and renovated.

In 1987, Zahner was brought in by BNIM and and artist Tom Corbin to develop the custom architectural metal for the historic theater’s restoration.
Working from historic photographs, Zahner worked to carefully detail new fabricated components for the building’s metal marquee. Zahner artisans fabricated these parts in sheet brass and muntz, working to integrate the molded brass features cast by Tom Corbin in his foundry.
The end result is a golden marquee which resonates with the building’s original 1927 appearance.
