What is Wire Decking?
Wire decking is a product that works with pallet racks to provide support, safety and other benefits to warehouse racks. Wire decks are easy to install (they simply drop into place), and allow high visibility through all levels of pallet racking. In addition to providing protection from falling inventory, wire decking can improve air circulation and prevent dust build-up. Wire decks can also help increase overhead sprinkler effectiveness, and many local fire codes require them instead of particle board or plywood.
Wire Deck Options & Terminology
On the underside of each wire deck, support channels are welded to the bottom of the mesh surface. These channels give wire deck rigidity and load bearing capacity. Typically, wire decking uses three or four support channels and supports up to 2,500 lbs. Step channels provide more strength than flanged channels, however each has their own advantages.
Wire Mesh Pattern
Most wire decks made in the past 20 years feature a 2" x 4", 2.5" x 4" or 2.5" x 4.5" grid pattern. Sometimes you may see higher density grids, but these are usually made for applications that required hand stacking or storing small materials.
The term "waterfall" is used to refer to the end(s) of deck that hang below the deck's surface. Waterfalls provide additional protection to wire decks by making them more resistant to coming off of the pallet rack unexpectedly. The accepted industry standard for waterfall height is 1.5 inches. A shorter waterfall may be warranted where labels or bar codes are needed on the rack's beam face. Waterfalls can also be turned up to provide a back stop on a pallet shelf. Front and rear waterfalls can even be mixed so that one is up and the opposite is down.
Flush wire decks are useful for hand-stacking and order picking. The flush deck doesn't have edges that could catch an employee's hands. With flush decks, the deck depth measurement refers to the outside dimensions of the rack beams. If your racking is 42" deep (42" from outside to outside of each beam level) you will still need a 42" deep deck however the deck's depth will only be 38.25" deep - or approximately the depth of the inside of the steps of the beams.
Properly Loading Wire Decks
Please Note - Unless storing small or very light weight items on the pallet racking, wire deck is NOT meant to support loads directly. In other words, DO NOT point load wire decking. Pallets must be fully supported by the front and rear support beams.
