100 years of smart building with construction’s trailblazers

At McGregor Industries, we’re rethinking the way America builds.

Since 1919, we’ve tackled complex high-rise residential and commercial building projects across the U.S. As a family-owned and operated company, we manufacture and install stairs and railings for the nation’s leading architects, designers, construction managers and general contractors.

Meet McGregor Stair Systems™

McGregor Stair Systems™ was born out of a desire to solve the challenges you face every day – delayed schedules, coordination issues, unsafe job sites, and more. We chose to do things differently, creating a revolutionary way of building tower stairs that’s transforming construction.

See why steel is better than concrete for your next stair project.

The McGregor Difference

All under one roof

We handle every point of the production cycle in-house – from detailing to fabrication to installation – which means we can react to changes quickly, reduce costs and ensure precision every step of the way.

Leading with technology

While other manufacturers use CAD drawings to design your stairs, we don’t. We customized our BIM (Building Information Modeling) design process to use Tekla, which creates a true, virtual model of your project that can be integrated into the overall project model.

Easy installation

We deliver our stairs in bundles, which typically include two stairs, a landing, railings and embeds – requiring less iron workers and making installation a hassle-free process to save you time, money and aggravation.

"We're proud to have worked with many of construction's innovators and game-changers, who share our drive for being industry leaders. Our customers know they can rely on us, and that we do everything in our power to meet our customers' needs and timelines. Going the extra mile is the norm at McGregor, and if there are any problems on the site, we do whatever it takes to get it right."
