4/12 Pitch Trusses

A 40-foot span truss with a 4:12 pitch would measure 40 feet (480 inches) across the bottom chord. The vertical rise to the peak would be approximately 6 feet 8 inches (80 inches), calculated as half the span (20 feet or 240 inches) multiplied by the 4/12 ratio. FrameX engineers each truss panel to project specifications, providing stamped structural packages and precise panel layout drawings with all dimensions clearly documented.

A 4/12 roof pitch corresponds to an 18.43-degree angle from horizontal. However, FrameX cold-formed steel trusses are precision-manufactured off-site with all cuts, angles, and connections factory-fabricated. You receive installation-ready components requiring no field cutting or angle calculations. This eliminates measurement errors, reduces labor costs, and ensures dimensional accuracy across the entire roof assembly.

Truss pricing varies based on span, pitch, load requirements, panel configuration, and project scope. FrameX provides transparent budget pricing upon submission of project plans through our quote request form. Pricing includes engineered design, BIM coordination, stamped structural packages, precision manufacturing, sequenced delivery, and installation documentation.

Cold-formed steel trusses can span significantly longer distances than traditional framing, often exceeding 40 feet without intermediate support, depending on engineering design, load requirements, and truss configuration. FrameX engineers each truss system using BIM coordination and structural analysis to meet project-specific load conditions and building codes. Maximum span capabilities are determined during the design phase and documented in the stamped structural package.

Cold-formed steel trusses offer superior strength-to-weight ratios, dimensional stability, and resistance to warping, rot, and fire compared to wood. Galvanized steel does not decay, absorb moisture, or degrade over time. FrameX trusses are precision-engineered with BIM models to ensure predictable structural performance, eliminating issues like wood shrinkage or inconsistent material quality. Each project includes stamped structural packages confirming compliance with engineering standards.

Every FrameX project includes a complete documentation package: stamped structural drawings signed by a licensed professional engineer, engineered shop drawings, panel layout drawings showing installation sequence, BIM coordination models for project integration, and installation documentation with assembly instructions. This comprehensive package reduces RFIs, ensures code compliance, and provides clear guidance for efficient on-site assembly and inspection approval.
