Abstract: A metal lath having an integral hem structure includes a main body. The main body is formed by enclosing the metal lath so that the main body has a ring-shaped side wall. The side wall defines an accommodating space therein. Two ends of the main body are formed with openings to communicate with the accommodating space, respectively. One of the openings is integrally formed with a hem around an end edge of the opening by bending. The hem is integrally formed with the metal lath, which can reduce production time and cost effectively and can prevent the user from being cut by the metal lath.
