Structural Precision

Engineered for alignment. Streamlined for installation.

Secondary framing is what brings order and confidence to the building as it takes shape. It supports the structure quietly but decisively, helping walls and roofs come together with clarity and consistency. By opening interior space and simplifying construction, it allows the building to work harder without feeling constrained. Precision and coordination across the system reduce uncertainty during installation and reinforce stability over time. Integrated as part of a complete Butler building approach, secondary framing helps the entire structure perform as one delivering strength, efficiency and reliability that last well beyond completion.

Features

Factory punched connections improve fit, speed installation and reduce field variability.

Factory-punched accuracy: Pre-punched connections improve fit, speeds installation and reduce errors.

Designed to integrate with Butler® roof and wall systems for coordinated system performance.

System-wide integration: Designed to align with Butler roof and wall systems for unified performance.

Roll formed top and bottom chords use bolted connections to eliminate weld variability.

Truss PurlinXT

Engineered for spans up to 60', Truss PurlinXT features a factory-assembled, pre-punched design that improves erection speed and accuracy. Its lighter weight reduces freight cost and provides long-term corrosion resistance. 

  • Roll-formed top and bottom chords are bolted, eliminating welds for consistent fabrication. 
  • Its long-span capability supports spans from 12 – 60' with depths of 30", 34", and 40" for optimized performance.
  • G30 galvanized finish, factory-punched holes and bridging indicators streamline installation.
  • Up to 36% less weight than conventional bar joists across typical bay conditions.
