The shelf is a Jula 650 V. Perhaps this is not mentioned because it is poorly rated? Described: for professional and private use, stable. Sheet thickness 0.7 mm, 23 kg. Sheet of floors: 0.5mm, 21 kg, is available in the assembly instructions, it is essential to attach to the wall. See reviews on Jula 650 - more suitable for children's, if it were not so sharp. A few weeks ago I bought at warehouse compact shelf following: "Storage rack 200 x 120 x 50 cm 5 shelves Modular shelving Schwerlastregal galvanized shelf" does not exist currently - luckily, see my comment there. Also good for nothing. Was too lazy to disassemble it again and send it back, it was reinforced with rivets. I expect for that price is not the same as a 150-shelf. But at least a correct description. Telephone contact with the company - if it actually was a Jula, as in the account named after the purchase - was ok. I'll send the shelf back - no fun at the weight, to bring it to the post office. Certainly no more rack of compact storage.
