 Traditionally, the metal used for the gandingan was bronze but due to its scarcity, gandingans are more commonly made of less valuable metals such as brass and even iron. Recently, galvanized iron sheets have been used where different parts of the gong (the knob, body and rim) would be made from separate sheets and welded together, then grinded out to produce a finished product. Comparatively, these newer gongs have a higher pitch and are smaller in size than those made in older times.
