What is the maximum capacity and maximum net weight for steel, aluminum, and other metal drums?

• A. 450 L, 450 kg
• B. 600 L, 600 kg
• C. 500 L, 200 kg
• D. 400 L, 800 kg

Answer: (A)

Metal drums used for transport have fixed safety limits for both how much they can hold and how heavy their contents can be. The standard maximum internal capacity is 450 liters, and the maximum net weight of the contents is 450 kilograms. The capacity is the space inside the drum, while the net weight is the payload of contents (tare weight of the drum is not included). These limits are set to ensure the drum can be safely handled, lifted, and stacked, and to account for the drum’s structural strength. Because densities vary, the actual fill must respect both limits—whichever becomes the limiting factor (volume or weight) determines how much you can put in. This is why 450 L and 450 kg is the correct pairing.
