Stair Systems

Ready-to-install stair assemblies that keep your build moving—fast.

Your Go-To Source for Engineered Stair Solutions

Pacific Wall Systems designs and manufactures prefabricated stair systems that meet code, arrive job-ready, and install in a fraction of the time compared to site-built stairs. Whether you’re framing multi-family housing, commercial spaces, or custom homes, our stair assemblies help you avoid delays, reduce on-site labor, and ensure a safer, smoother build.

Why Builders Choose Our Stair Systems

  • Code-Compliant, Every Time
    Each unit is designed to meet local and national codes for rise, run, and load—no last-minute field fixes.
  • Delivered Job-Ready
    Stair runs arrive fully assembled, ready to drop into place and secure—saving critical framing hours.
  • Consistent Quality
    Built in a controlled environment using precision jigs and quality lumber, so every tread and riser is true.
