Ive seen lots of wirework shelving units but i have something 'sort of' along those lines. Can you buy just a wirework shelf that could be used in my existing unit to replace old mdf shelves?. Dont need the weight or wood or mdf but similarly dont need a metal self contained. Unit. Anything about 300 deep by about a metre that i can buy some of?.. As url link here sort of idea?https://cdn.shopify.com/s/files/1/0...4-shelf-28025547063383_2000x.jpg?v=1665708066
