The most common kitchen shelving is flat or wire shelving. Though it is takes longer to clean, wire shelving is sturdy enough to hold heavy items and air is well circulated around food products. Flat, solid shelving is also sturdy and can hold various product loads depending on the thickness of the shelf. They can prevent spills from leaking down below which could lead to contamination. However, air is not circulated as well among food products on flat shelving. Embossed shelving contains ridges that are imprinted in the surface. The ridges raise food products up off the surface for better air circulation. Slotted shelving circulates air well, but the slots also permit spilled liquid to leak below. Many solid shelves have a lip around the edges to prevent this from occurring. Something you may want to keep in mind when looking for kitchen shelving is how complicated it may be to clean. If you want a shelf that requires minimal cleaning, you may not want to choose one with tight crevices. Also, wire shelving will take longer to clean than flat shelving. It is best to purchase shelving with a NSF (National Sanitation Foundation) label for certified, sanitary protection. Choosing the type of shelving material you like best will also be a factor in your decision. Stainless steel is non-corrosive and lasts a long time without chipping. Polypropylene, as well as epoxy coated shelving, is resistant to most acids, chemicals and damp environments. Epoxy coated shelving is also impervious to rust and corrosion. Chrome has a high gloss finish that is durable and resistant to rust and corrosion. It is ideal for dry storage. A good choice of shelving will allow you to utilize the area you have and allow you more space to store items.
