Buy Old or New Pallet Rack?Wednesday, November 18, 2009
Old rack is ok for straightforward use; for complexity, longevity, expansion, or
seismic issues, new rack is best.
In the tough economy, many manufacturers are tempted to save a little by purchasing used pallet rack. While this can be a viable option, it can cost more than expected and have limitations down the line. So when does it make sense to buy old vs. new pallet rack?
In general, buying used storage rack can make sense when it's in decent condition, relatively new, used in a non-seismic situation, and basically just needed for the uprights and beams, not a specialized system.
However, seismic map changes and stricter requirements make getting help more of a necessity today than in the past. "Only a few areas were designed to seismic requirements in the past," says Steel King Engineer Arlen Keck. "Now the requirements are stricter and the zoning broader. If you buy rack in one area, it may not pass code in another." Steel King, a major designer and manufacturer of warehouse material handling, storage, and safety products, has been helping plan warehouses since 1970.
Changing building codes and certification requirements, too, can make buying used rack a little more iffy. The Rack Manufacturers Institute (RMI) publishes a racking design specification, and the American Iron and Steel Institute (AISI) and American Institute of Steel Construction (AISC) each publish a steel design specification. Your racking system must be in compliance with these specifications along with your local building and fire codes.
Current RMI certification, for instance, requires a load plaque stating maximum rack capacity for fork truck drivers. Older warehouse rack not only may lack such load plaques, but also rack capacity documentation.
"As a rule of thumb, if you can't easily find used storage rack capacity and documentation online, you should probably pass," says Keck. "The same is true if the manufacturer is out of business, or the product line is discontinued."
"An advantage of buying new pallet rack is that it usually includes help with seismic calculations and permitting," adds Keck. "Without such help, someone buying used rack may need to pay for testing and consulting fees, which could erode any initial savings."
It usually makes sense to buy new pallet rack when it'll be used in a high seismic zone, for more complex or integrated systems, and when future add-ons or extensions are likely, according to Keck.
Along these lines, new pallet rack can be custom fit to a warehouse's size, capacity and process, whereas older rack usually requires more compromises or "workarounds" to fit existing facilities. For these reasons, Keck recommends new rack for any specialty applications such as pick modules with floorings, integration with other products, and automated handling systems.
Newer warehouse rack also tends to have the advantage of being constructed from premium steel, with yield strength in 50,000-psi range, as opposed to older commercial steel, typically in the 33,000-psi range. Since the newer premium steel is about 50 percent stronger, this translates into higher rack structures, greater capacity and seismic resistance.
New storage rack also tends to have better quality control and beam fit, with closer tolerances and plumber racks. This aids material handling efficiency and reduces maintenance. The impact and chip resistance of newer racks' powder-coated paint is also significantly better than older racks' typical spray paint, which further reduces maintenance and enhances appearance.
So when does it make sense to buy old or new pallet rack? For the most straightforward applications, older rack may be fine. But for anything where complexity, longevity, or expansion may be involved, new rack may be the best choice. To do otherwise, may be "penny-wise and pound-foolish."
Steel King is the nations' only single source manufacturer of pallet rack, pushback rack, drive in rack, portable rack, cantilever rack, custom shipping rack, mezzanines, pick modules, industrial containers, and industrial safety guard railing. It is an active member of the Rack Manufacturers Institute (RMI), the Material Handling Industry of America (MHIA), the Storage Equipment Manufacturer's Association, Reusable Container and Pallet Association (RSPA), and the Material Handling Equipment Distributors Association (MHEDA).
