A coal bucket is a common metal storage and transport container, primarily fabricated from galvanized iron sheets and finished with a spray coating or surface treatment to achieve a smooth exterior. It typically features a conical or cylindrical design with an open top, facilitating the easy loading and pouring of coal or other solid fuels. The body of the bucket is fitted with a handle to facilitate carrying and maneuvering, while its base is reinforced or flattened to ensure stable placement on the ground.
