ROOF TRUSSES
are engineered structural frameworks, usually made of wood or steel, that support the shape and load of a roof. They replace traditional rafter-and-ceiling joist construction and are widely used in residential and commercial buildings because they are cost-effective, strong, and fast to install.
Key features
* Prefabricated: Usually manufactured off-site to exact specifications.
* Triangular Shape: Uses triangles because they are inherently stable and can efficiently distribute loads.
* Top Chords: Sloped members that define the roof pitch.
* Bottom Chord: Horizontal member forming the ceiling line.
* Webs: Internal members that connect the top and bottom chords, forming triangles for stability.
Advantages
* Efficient load distribution
* Quick installation
* Material savings vs. stick framing
* Customization for various roof shapes
* Can span large distances without interior supports
Installation Tips
* Bracing is essential during and after installation.
* Avoid field modifications unless approved by the truss engineer.
* Proper handling to avoid bending or cracking.
