Hollow Metal Door - Tenant Finish Cyclicality

I am looking at a Hollow Metal Door installer that does ~50/50 new construction and tenant finish projects. Does anyone know of any industry reports or data sources that would help me get a sense for the cyclicality of the Hollow Metal Door industry, especially on the Tenant Finish side?

I'd definitely expect some cyclicality, but am trying to understand where on the spectrum this industry has been historically.
