Important engineering notice:
Beam & Header Calculator Pro is a preliminary drafting and mathematical assistance tool. It does not select or approve structural members and is not a substitute for a licensed structural engineer. Users must verify all loads, material properties, assumptions, calculations, connections, bearing conditions, code requirements, and project-specific conditions. Do not rely on its output alone for construction, permitting, fabrication, purchasing, or life-safety decisions.
