Features to Consider When Selecting a Glass Storage System
Moving through the Options
by Hank Groves
Safety must be a top priority when selecting your glass storage system. A large majority of glass companies have experienced breakage due to rack failure or improper glass storage. Listed below are some points to consider when selecting your system.
Glass packs vs. wooden cases: Can you afford to use wooden cases when glass packs are available? Examine your handling costs, disposal costs, labor to remove glass from cases and the cost per-lineal-foot for warehouse space and safety.
Handling costs: Examine the labor time spent opening a wooden case and the time required to remove the empty case. You will find at least one man hour per case is required. Multiply this by the number of cases you handle in one month.
Disposal costs: These costs continue to rise due to the shortage of landfills available. Glass packs could save you up to 75 percent of wooden case disposal costs.
Glass removal: Glass packs can be removed easily from the case using suction cups. Wooden cases require tongs, which can be time-consuming to use, especially when removing the first few lites from the case. Chances of breakage are also greater with wooden cases than glass packs if the nails are not removed from the case completely.
Warehouse space: A case of 72-by-100 glass packs measures 61/2 inches wide. The same case in wood measures 9 inches wide. The wooden case takes up the same room empty or full. With glass packs, every time you remove a piece of glass, you are decreasing storage space. But, when you bring in a replacement wood case, you need to find another area for storage disposal until the old one is completed. When using glass packs, the replacement case can be positioned next to the existing case when using a heavy adjustable post system. Compare your lineal footage cost for warehouse space using wood compared to glass packs. You can double the number of cases in the same lineal footage using glass packs.
Fixed post or adjust-a-post racks: Fixed post systems work very well for glass fabricators who use a limited number of glass sizes. Laminated and tempering companies use cases of 96-by- 130 glass measuring 31/2 inches wide. Have your rack manufacturers space the posts to accommodate your most popular widths.
Adjust-a-post systems are better suited for the glass distributor and smaller glass shops that use a variety of sizes. Posts that can be adjusted horizontally slide in outside rails to butt on each side of the case, thus eliminating unused portions of the rails.
Alternate post, then case, then post for maximum case storage. As your inventory is used, space opens up for replacement cases by adjusting the posts. When using glass packs, make sure the system you choose has posts capable of holding more than one case.
Both fixed and adjustable post systems need a center rail for support when sliding lites out of the racks. Make sure the rails and posts are covered with an easy sliding material for ease of removal.
Safety: Make sure the rack heights are at least 51/2 inches from the floor for alignment of glass with dolly used for transporting.
Bolting racks to the floor can prevent the racks from moving when hit accidentally. It is
important to beware of lightweight steel
construction and also to ask for engineering tests. Load ratings should be a minimum of 150 percent of the weight being applied.
Ask your glass storage system supplier for help when laying out your new system. He should be able to show you the lineal footage needed for storing your cases in both wood and glass packs.
Just Too Slic: Slic-Rak Serves as Space, Time and Money Saver
Have you ever wished there was a product you could use to increase glass rack storage capacity in the shop, and that you could also use on truck racks to double efficiency and eliminate extra delivery trips? Look no further. Los-Angeles-based C.R. Laurence has introduced the CRL Slic-Rak® Glass Rack Expander System.
The system was developed by a glass shop owner who wanted to increase rack capacity in his shop and maximize the storage space on his truck, said Rick Nelson, CRL product manager. According to Nelson, Slic-Raks are unique because they create a ledge board anywhere on a storage rack and work with existing stakes or ropes. Additionally, they are adjustable for slats up to 2 ¼-inches thick and fit anywhere on a glass rack. You just slip them on the slats and tighten the wing nut, said Nelson. Install them on a mobile glass rack and you can save a lot of unnecessary trips back and forth to the shop.
Another benefit of the Slic-Rak is that it allows material to be stored out of the splash zone. According to Nelson, this can prevent chipping from stones, dirt and sand, and can eliminate the need for extensive re-cleaning of glass at the job site.
Slic-Racks are made from ¼-inch thick, structural grade aluminum with neoprene rubber padding for glass support, cushioning and protection during transport and storage. Sold in pairs, each CRL Slic-Rack weighs less than three pounds and measures 4 inches long, 6 inches high and 2¼-inches wide. According to Nelson, no tools are needed for installation and an extra long rust-resistant bolt provides an instant handle for gripping when tightening the wing nut.
