A metal drum frame with fixing lugs. A drumhead is mounted on each end face of a drum barrel of the drum. A drum frame is mounted around each drumhead. A top and a bottom edges of the drum frame are respectively formed with hollow bulge lips. A portion of the drum frame between the lips is recessed to form a waist section. The waist section of the drum frame is formed with several outward extending lugs. The lug is formed in such a manner that the waist section is transversely cut with two parallel cut lines defining the lug. The portion of the waist section between the two cut lines protrudes outward to form a substantially hollow hoop shape. A locking member is disposed in the lug. A bolt is passed through the locking member to tension the drumhead.
