Hi and thanks for the question! These stainless steel base cabinets were custom-made locally by a metal fabricator (the same type of fabricator you might use to create custom stainless countertops). They do not have a specific name. If you are unable to locate a metal fabricator in your area, you may be able to find shelving/cabinetry online at a restaurant supply store such as The WEBstaurant Store. Check out this page as a start: http://www.webstaurantstore.com/43753/enclosed-base-commercial-work-tables-without-doors.html
Hope this helps! -Emily
