Wood Filled Upright Column


UNARCO’s Wood Filled Upright Column Insertcombines two materials for one amazing result.  The energy from impact is absorbed by wood helping the pallet rack upright column better maintain it’s shape and integrity.  Specially routed hardwood is shipped inside the column in any height needed.  The shape allows for beam placement in both T-Bolt  andInterchangeable pallet rack.

The UNARCO Wood Filled Column was tested against structural upright column shapes and an array of roll-formed upright sizes.  In trial after trial, the Wood Filled Upright Column held it’s shape better against every column. The Wood Filled Column structural integrity was maintained throughout every iteration.

Testing involved the simulation of a moving forklift and impact from a 1,000 pound weight from 22″ at a speed of 5.2 mph.  The Wood Filled Column absorbed the shock and upright column damage was nearly half of the damage of the structural channels.  View the video testing at the following link

UNARCO uses treated wood to maximize the longevity of the insert.  In addition, testing and engineering trials have created the most effective shape to allow perfect fit of T-Bolt and Interchangeable beams against the post.  Inside the column, the wood  transfers the energy of the shock away from the steel column which minimizes damage to the pallet rack upright.

  • Wood Filled Column Insert – Available in any height for impact protection.
  • Wood absorbs the shock of impact
  • Special slotted design helps maintain the shape of the upright column.

One of the smartest and most cost effective methods of upright column protection available is such a simple idea.  Because the wood is inserted inside the column before shipping there are no additional charges for installation.  Another benefit is the extra aisle clearance gained as the insert is not fastened to the outside of the pallet rack upright as other column protectors which are installed on-site.  More evidence of how UNARCO engineering can take a SIMPLE idea and create a SMART solution.
