1. A fire-rated component for sealing a head of wall gap, the fire-rated component comprising:
an elongate body comprising a non-metal material, the elongate body comprising:
a lower portion comprising a planar fastening segment configured to allow the fire-rated component to be secured to a flange of a header track of a wall assembly; and
an upper portion comprising a planar upper segment and a curved segment extending from an upper edge of the planar upper segment and located on a first side of the planar upper segment;
wherein the planar fastening segment is offset from the planar upper segment in a thickness direction of the fire-rated component on the first side of the planar upper segment;
a metal sheet attached to the planar upper segment of the elongate body; and
a heat-expandable fire-resistant material strip attached to the metal sheet.
