Bulk storage and specialty racks for material that will not sit on a standard pallet rack: cantilever racks for pipe and lumber, vertical sheet racks, bar racks, portable stacking racks and Tier-Rack pallet stacking frames, gravity flow racks and pre-engineered bulk storage racks. Cantilever racks are specified by arm capacity and arm length, since the load hangs off the column instead of resting between two beams. Portable stacking racks and stacking frames let you stack loads that will not stack on their own, with no permanent structure, and they knock down when the season ends. Wire mesh and all-welded steel decking are listed here as the shelf surface for rack you already own.
