Palletecture yields savings of both material and financial resources

For a kitchen/bath industry show and conference, Crystal Cabinet Works designed and built its own trade show booth using 120 shipping pallets.

“If we’d built this booth out of typical exhibitry, it would have cost us hundreds of thousands of dollars,” [Don] Papa says. “But with the reused pallets and internal labor, the materials and construction were practically free.”
