Our Story

Where We Started

Port City Architectural traces its beginnings to 1940's Muskegon, Michigan, a town with deep roots in the metal casting industry.


Mills Manufacturing opens, making cast iron belt buckles and machine plates and eventually, building letters and plaques.


After 60 years in business, Mills Manufacturing falls on hard times and shuts its doors.

Oct. 2006

Port City Architectural buys Mills’ used equipment at auction and sets up shop in Muskegon Heights, serving former Mills customers.


Port City sets up a greensand foundry operation in Muskegon, producing primarily golf course signage.


In response to the great recession, Port City diversifies by introducing Signature Streetscapes, a new brand of custom decorative streetscape signage, house plaques, and lighting.


Port City expands with a new airset molding foundry operation, requiring the design of new tools and processes. Finished castings feature stunning detail, Port City increases capacity and as sales grow, the company starts to run out of space.


A new building expansion brings more processes under one roof, including powder coating and a state-of-the-art print shop. The new operation reduces delivery times and allows Port City to better serve customers with premium, 100% USA-made products.


Port City brands its premier line of golf course signage and markers as Major Markers.

And Beyond

At Port City Architectural, we’re positioned for a bright future as we produce best-in-class solutions through our Major Markers and Signature Streetscapes brands.
