These design metal moulds are used to make boundary wall concrete plates. These design metal plate moulds have nuts and bolts on the sides. When the concrete dries up, the concrete plate is taken out by opening those nuts and bolts. These design metal plates are installed in a line in 10 pieces. Rafik Engineer  Works fabricate these design metal plate moulds. A 4 mm plate is placed in the base. A 3 mm plate is placed in the side molding. Inside this, 3 mm and 4 mm wire is inserted to make the concrete plate. There wire are prestressed by the jack before casting.
