"Heavy duty" refers to items or materials designed to withstand significant stress, wear, or load. These products are often used in demanding environments, such as construction sites or industrial settings, where durability and strength are essential. Examples include heavy duty tools, equipment, and fabrics that can endure tough conditions without breaking down. In consumer products, "heavy duty" can indicate a higher quality or performance level compared to standard versions. For instance, heavy duty trash bags are thicker and more resistant to tearing, making them suitable for disposing of heavier waste. This designation helps consumers choose reliable options for their needs.
