Wood top work tables are not as common in the food service industry as they used to be. With the advent of food safe stainless steel and poly top work tables, wood tables are seen less often in food preparation areas. The reason is simply that the wood is not NSF approved, making it unacceptable in many health inspectors’ eyes. However, wood tables are still found in bakeries, since these applications do not typically involve the types of food items that full-service restaurants do. These tables are often constructed with I-frame bottom configurations, making for a very sturdy, durable work surface.
