Plate and Sheet Rolling: How Best to Pack Cylinders

When packing and shipping boxes full of rolled sheet or plate cylinders, we want to pack them hexagonally instead of square.  Because that way:

  • You fit more into each box.
  • There’s less space between pipes, because each pipe is contacting 6 other pipes around it instead of 4.
  • It minimizes chances of their sliding around, getting dented in transit, or being sent back to be repaired or replaced.
  • And it’s still easier to count them because they shift less in the box.

This topic of minimizing the chance of sliding around reminds us of interstitial atoms in steel — the carbon particles that pack into iron lattice that make the sheets of the lattice harder to slide around (and therefore, stronger).
