Build Jobsite Stairs with Fast-Stairs® Stringers Kit

Construction jobsite stairs easily made with prefabricated rust proof steel stair stringers.

If you’d like to vastly improve building site safety and efficiency, now you can build long lasting, movable and reusable (over 50 jobsites) jobsite stairs thanks to Fast-Stairs® modular adjustable steel stair stringers. Builders, contractors and framers now save 80% (over time) on jobsite “temp” stair costs while contributing to eliminate needless landfill lumber waste. No more filling the dumpster with broken down wooden “temp” stairs. Other Fast-Stairs® jobsite stairs benefits are:

  • Hands-free alternative to ladders and scaffolding
  • Adjustable In height (12″) and width
  • Rust proof
  • Super solid (1 ton capacity)
  • Quick and easy assembly
  • 85% made of recycled steel
  • OSHA standards compliant stair models
  • Economical (pennies a day!)
  • Limited warranty
  • New easy to ship and carry (max. 70 lbs) packages

Designed for fail-safe DIY jobsite stair building and installation

Fast-Stairs® provide a unique, quick and easy way to build long lasting, free-standing 2½ to 13 ft high jobsite stairs. No stair stringer calculator required. No more figuring out the rise and run of steps. Simply measure your floor to floor vertical height and then choose online the Fast-Stairs® adjustable model that fits the desired height of your jobsite stairs. We recommend our space saving C models (8¼’’ riser height, shorter stair run). Our patent pending adjustable (at every ¼’’) 12 inch, ¼” steel top hook straps allow our jobsite stair models to typically move from 8 ft to 9ft ceiling sites or from 9 ft to 10 ft ceiling sites and more depending on your choice of jobsite stair model.

Green building jobsite stair safety, efficiency & economy

Fast-Stairs® offer do-it-yourself jobsite stairs solutions for consumers, re-modelers, builders and contractors alike. There is no faster, easier or better way to build super strong and economical jobsite stairs. Simply bolt the stringer sections together with the slide connectors and screw the step/treads (not included) of your choice to the perforated welded steel step supports. The simple method for attaching railings to your jobsite stairs is with railing posts fastened from inside the perforated steel stringers and railing boards fastened to posts above the box steel stair stringers. You do the job in minutes.
