Open Web Steel Floor Trusses

A floor truss span depends on the truss depth, steel gauge, chord and web design, spacing, design loads, bearing conditions, openings, and applicable building code. Open web steel floor trusses can be engineered for longer clear spans than conventional framing in many applications, but there is no universal maximum. A qualified engineer should design the truss layout for the specific project.

Yes. Floor trusses are structural, load-bearing members that transfer floor loads to designated bearing walls, beams, columns, or other supports. They are engineered to carry dead loads from the building materials and live loads from occupants, furnishings, and intended use. The supporting structure, connections, truss spacing, and loads must all be coordinated as part of the engineered framing design.

Three common structural truss configurations are Pratt, Howe, and Warren trusses. Each uses a different arrangement of diagonal web members to distribute forces between the top and bottom chords. In floor framing, teams may also compare open web trusses, parallel-chord trusses, and solid-web joists. The best configuration depends on span, loading, MEP routing, depth limits, and connection requirements.

Open web steel floor trusses provide clear pathways for plumbing, electrical, fire protection, and HVAC services without extensive drilling or cutting through solid members. Cold-formed steel also resists rot, warp, decay, and fire. When coordinated through BIM and manufactured from engineered models, the system can reduce material waste, on-site fabrication, field adjustments, and schedule disruption.

Yes, open web steel floor trusses can be engineered for commercial, multifamily, institutional, and residential applications. Their capacity is determined by project-specific loading criteria, span, truss depth, steel thickness, spacing, bearings, connections, and deflection limits. The structural engineer evaluates these factors and prepares the required design documentation so the framing system performs as intended.

Coordination should begin during preconstruction, before final fabrication and ideally before other building systems are fully locked in. Early review allows the team to align floor elevations, bearing locations, shafts, penetrations, mechanical routes, and connection details. Frame X Systems uses constructability review and BIM framing coordination to identify conflicts early, when adjustments are typically faster and less disruptive.

Pricing is developed from the project plans and framing requirements rather than a standard per-truss rate. Scope factors include building layout, spans, loads, truss depth, steel specifications, engineering, BIM coordination, manufacturing complexity, delivery sequencing, and project schedule. Frame X Systems provides budget pricing and project review after receiving plans and relevant project details, followed by a tailored proposal.

Yes. Frame X Systems has national delivery capability for installation-ready cold-formed steel framing packages. Delivery is coordinated with the construction schedule and can be sequenced to help limit jobsite congestion and material handling. The team serves projects nationwide, including work in the Dallas–Fort Worth area, Denver, and Phoenix, while coordinating design and engineering requirements for each project.
