SPECIFICATION AND PROCUREMENT / FIELD NOTE 41
Calculating Honeycomb Panel Order Area and Waste
Installed face area, developed blank area and purchased stock area answer different questions. Returns, machining allowance, grain direction and sheet stock dimensions can increase purchase quantities.
What to check on your project
Keep the three area measures in separate columns. Use finished dimensions in the face-area takeoff, and let the fabricator check the blank development and nesting. Compare supplier prices against an agreed area basis.
Worked example
Ten finished faces measuring 1,200 × 2,400 mm cover 28.8 m². If the fabricator’s confirmed flat blank is 1,260 × 2,460 mm, those blanks total approximately 31.0 m² before stock nesting. The 2.2 m² difference comes from the blank dimensions in this example. Stock yield is a separate step and depends on the sheet layout.
