Innovation & Experience

Customer-centric software and solutions
for the construction industry

Our Story

From our humble beginnings in a basement in Chicago in 1975, Keymark Enterprises has built software to support wood trusses, wood I-joists, SIPs, light gauge steel and other innovative products.

Steel Solutions

We moved to developing light gauge steel solutions in 1993. While we think we are the best in the business at building technologies, what we are most proud of is the way we listen to our customers. The ISF Product Suite, including the best of breed, patented KeyTruss steel truss system is a comprehensive, integrated system of steel software, steel frame roll formers, product development, and support services to fulfill all your cold formed steel framing needs.

Post Frame Software

Over the past two years, the post frame industry has grown exponentially. To help our distributor and contractor partners compete with the big boys, we developed the pole barn industry’s only complete design system for post frame structures. Simple enough for anyone to use, this web-based software quickly generates a 3D model, material lists, pricing, proposals, and construction documents for almost any post frame building. 

Our Team

We are a team of down-in-the-trenches, sleeves up, hands-on profressionals. Our best days are working closely with clients to understand what they need, apply our industry experience and deliever a seamless, efficient solution. 


Ask our employees what makes Keymark such a great place to work and they’ll all tell you, “It’s the people.” It may sound cliché, but it’s true. And it’s no accident. Here at Keymark, we look beyond basic skill-sets and deliberately seek out job candidates who possess a positive, “can-do” attitude. People who are happy, energetic, and well-balanced in life. Creative thinkers who enjoy working in a highly collaborative and supportive team environment. People who genuinely care about the work they do and those they do it with. 

The concept may be simple, but the results are profound. If Keymark sounds like the kind of place you’d like to work, we encourage you to reach out.
