Wrought iron folding drying rack 3 layers 150cm long

▸ Material structure: wrought iron three-layer folding frame
▸ Unfolded size: length 150cm
▸ Load-bearing parameters: static load-bearing ≤25kg (need to confirm whether this parameter exists, the original description is not mentioned) Note: The actual optimization needs to be strictly based on the input information, and this case is only a basic transformation demonstration due to the limited parameters of the original data
