The primary cost drivers are aluminum alloy grade (typically 6063-T5) and profile thickness, which should be at least 1.2mm to 1.5mm for structural stability. Additionally, the surface treatment (anodized, powder-coated, or electrophoresis) significantly impacts both the aesthetic finish and long-term corrosion resistance. Buyers should also verify the density of the acoustic panels (usually polyester fiber or fabric-wrapped MDF) and the load-bearing capacity of the desktop, which should ideally exceed 80kg.
