When evaluating aluminium cabinets, prioritize the grade of the aluminium alloy, typically 6063-T5, which offers excellent structural strength and corrosion resistance. Pay close attention to the panel thickness, which should ideally be between 0.8mm to 1.2mm for durability. Furthermore, verify the surface treatment technology; powder coating or electrophoretic painting are preferred for their resistance to scratches, moisture, and high temperatures common in kitchen environments. Ensure the hardware components, such as hinges and drawer slides, are made of 304 stainless steel to prevent rust.
