POSI-STRUT FLOOR SYSTEM
Lower your total costs in shallow depth floor projects by using Posi-Strut® metal web floor trusses.
DESIGN AWAY COSTLY FRAMING MATERIAL
Posi-Strut® metal web floor trusses are stronger, lighter, and easier to install than other shallow depth floor joists. The open webs allow MEP runs to be easily routed through the system, eliminating the need to cut, drill, or add dropped ceilings.

Benefits
- Design Flexibility: Higher ceilings, fewer soffits, and bigger rooms
- Framer-Friendly: Lightweight for easy handling, and a 3.5” nailing surface for quality sheathing installs and safer walking
- Concealed Beams: Use a top chord bearing condition to hide beams and improve the architectural aesthetics
- Quality Construction: Custom-built to precise engineering specifications
- Energy Efficiency: With ample space between chords, HVAC runs can be optimized to reduce 90-degree turns
- Vibration Reduction: Design with vibration in mind by limiting deflection and adding additional strongbacks
- Fire & Acoustic: A variety of both new and improved fire-rated and sound transmission assemblies
The elimination of costly fire-retardant materials leads to fewer RFIs and delays, allowing for the efficient design of shallow-depth floor systems for multi-family projects
Everyone Benefits
- Structural Engineer: Strength allows for longer spans and heavier loads, providing adaptability to meet the building’s needs and design flexibility for various building conditions.
- Architect: Conceal MEP in webs, reduce drop ceilings and soffits, and achieve a two-hour fire rating at depths as shallow as 12 inches using fire dampers.
- General Contractor: Design versatility facilitates easier coordination with other systems. Fewer change requests and greater certainty of outcomes result in fewer headaches.
- MEP Contractor: Faster installation with less material.
- Framer: Lighter trusses are easier and less timely to install, leading to reduced repairs or rework.
