ABSTRACT:
A metal plate of the present invention includes at least one bead having a bead body and a bead end portion terminating in the middle of the plate. The bead end portion has curved edges connected to edges of the bead body. The distance between the curved edges of the bead end portion increases as the distance from an end of the bead body increases. Also, the height of the bead end portion gradually decreases as it approaches edges thereof. The metal plate may be used as a gasket or may be combined with other metal plates to constitute a steel laminate gasket.
