Letter from the President

Welcome to Keymark Corporation’s web address. This informational site was developed for those interested in our services to gain a strong perspective of our companies’ capacities and business mentality. The interactive portion of the site is designed to enter and track orders to final completion. Keymark Corporation has been providing quality aluminum extrusions to an array of U.S. Industries for over 50 years. We are committed to remain a privately held operation, which gives us the ability to tailor our service to meet your individual company needs.

Thank you for visiting here. We look forward to discussing opportunities and scheduling a visit to one of our facilities.

Sincerely,
William L. Keller III
President

Long Term Customer Relationships

Our commitment to developing and maintaining solid, long term customer relationships is just one of the many reasons Keymark has evolved into a leading aluminum extrusion manufacturer. Because Keymark has been serving the Building and Construction Products Markets for over 50 years, we are very familiar with the needs and challenges of this market segment. We are the leading extruder in the Building and Architectural Product Markets. We’re dedicated to supporting the Building and Construction Industries with products, services, and programs that promote outstanding design and exceptional customer satisfaction.

We provide innovative custom solutions to design challenges, while adhering to budget and other project parameters. Our customers count on Keymark for fast quote turnaround, short lead times, and reliable on-time delivery of premium extrusions with exacting tolerances to meet even the most demanding specifications.

Leading Edge Technology

Some things haven’t changed much at Keymark since 1964… for instance, we still pride ourselves in producing the finest quality extrusions possible. We still strive to exceed customer expectations with integrity, quality, responsiveness, and finishing capabilities. We focus on continuous improvement in all facets of our operations – service, capabilities, and production efficiency.

Other things have changed significantly… Like the sophisticated equipment now used in our manufacturing processes… Incorporating a “Lean” culture and manufacturing “System”. The goal of “Lean” is to remove the wasted effort from any process. We use “Value Stream Mapping” to identify those steps that add value to the process and the steps that do not. We then set a strategy for maximizing the value added steps, while minimizing the non-value added steps – “The Theory of Constraints”. We also integrate advanced technologies into every aspect of our operations. With a strong focus on constant improvement, we are committed to continually upgrading the computer and manufacturing equipment at our facilities to ensure we remain on the leading edge of emerging industry technologies.

Our state-of-the-art manufacturing operations also have fully computerized order processing, production scheduling, warehousing and delivery systems that ensure efficient production processes and short lead times.

 

Keymark Corporation is the First AEC Member to Complete and Publish An EPD Using AEC’s EPD Generator Tool

April 23, 2026; Libertyville, Illinois – The Aluminum Extruders Council (AEC) congratulates Keymark Corporation for being the first AEC member company to complete and publish an Environmental Product Declaration using the new AEC EPD / Product Carbon Footprint (PCF) Generator Tool. 

The EPD/PCF Generator Tool is a member resource that was developed by SCS Global Services for the AEC Sustainability Team.  Traditionally, an aluminum extruder facing customer demands for contemporary environmental information would contract with an environmental consultant; many months and many thousands of dollars later they would have the data. 
 

“We concluded that there had to be a better way – a means of generating the desired data as well as  testing “what ifs” quickly and cost effectively to understand how different factors play into the production of low carbon extrusions,” said AEC Sustainability Team leader Shane Tredup, President of Custom Aluminum Products in Sough Elgin, Illinois.  

Architects pursuing additional Leadership in Energy and Environmental Design (LEED) credits through the use of aluminum extrusion with low embodied carbon, automotive suppliers working to achieve the zero‑carbon goals set by their original equipment manufacturers (OEMs), and consumer goods manufacturers aiming to promote environmentally responsible products are all driving the growing demand for current environmental data and low‑carbon materials. 

AEC has created an online EPD and PCF generator designed to meet those needs efficiently. 

The tool lets extruders both produce accurate environmental data and also gain a clear understanding of their own carbon footprints to develop effective carbon‑reduction strategies.  

The generator tool enables extruders to evaluate how factors such as using billet produced with low‑carbon electricity versus coal‑fired power affect their overall carbon footprint and their customers’ EPDs. 

“Working with my peers in the industry and with SCS has been a fantastic experience,” said Kassandra Keller, Sustainability Director at Keymark Corporation in Fonda, NY, and member of AEC’s Sustainability and Building & Construction Teams. “I have learned a great deal about the world of EPDs and sustainability in working on this project. I believe this tool will allow anyone to be able to produce an EPD for their company. Whether you are a sustainability expert or novice, the tool makes it easy to operate and generate data. We started with the EPD for our casthouse production. Given how important billet is in determining the overall carbon intensity of our products, this data gives us the foundation for our EPDs that will cover various extrusion products;  we’re working on those now. This tool will allow us to stay up to date with our customers’ sustainability requirements and improve our own carbon footprint.” 

The tool’s development cost was shared among those members who want to develop their own EPDs or PCFs at a significant savings compared to developing their EPD on their own. Then a nominal yearly cost is paid to program operator SCS Global Services   for tool maintenance.

Keymark Culture

In the spring of 2007, Keymark Corporation set out on a journey to identify and enrich its safety culture. Recognizing the value of a robust safety culture and experiencing the difference, we are now using what we learned to institutionalize cultural values relating to “General Organizational Excellence”.

We began the safety culture journey by establishing the company objective of having a loss resistant organization. When researching for a methodology to achieve this goal, we found the work of Donald Eckenfelder, President, Social Operating Systems, Ltd. discussed in a trade journal. We met with Don and decided to use his “Values-Driven Safety” material and consulting services. He helped us to understand that culture predicts performance and can be measured and managed. Using the measuring tools, we identified the Keymark Corporation safety culture profile and undertook safety culture enrichment exercises to improve our safety values.

Taking the methodology to a higher level, we developed our own values for “General Organizational Excellence”. We now have a “General Organizational Excellence” culture profile. The next step encompassed exercises to reach these expectations.

The following are the General Organizational Values developed by a group of Keymark Corporation employees.

  • Culture Enrichment Values:
  • We always work safely
  • We can and will prevent accidents
  • We want a robust culture
  • We are a team
  • We support differences
  • We provide adequate tools training and technology
  • We treat our extended business family with respect …… always
  • We care about everyone who works here
  • We don’t quit. We are persistent
  • We follow procedures and exceed customer expectations
