Keep stringers, treads, and dimensions on separate layers.
The stringers are inset slightly from the edges of the treads, creating a floating effect while maintaining dual-beam rigidity. 2. Key Structural Components in a DWG Detail http:// YouTube·stairbuilding | Mistake | Consequence | Fix
Common sizes range from C10x15 to C12x25 depending on the span.
: The top profile of the stringer is cut into a zig-zag pattern matching the rise and run of the steps. Essential Layout Data Needed in a DWG Detail | Keep stringers, treads, and dimensions on separate
The basic double stringer is a broad category. Your choice of material and configuration will determine the structural and aesthetic outcome.
