Sill Assembly for a Threshold System and a Method of Producing the Same
A sill assembly is used in a threshold system and includes a sill deck having first and second deck surfaces opposing one another and extending between first and second ends. The sill assembly further includes a sill base formed of a polymer and coupled with the sill deck continuously along the first deck surface between and to the first and second ends of the sill deck for supporting the sill deck between and at the first and second ends. A method of manufacturing the sill assembly includes the steps of providing the sill deck and depositing the polymer to form the sill base coupled with the sill deck along the first deck surface between the first and second ends of the sill deck.

7 . The sill assembly as set forth in claim 6 wherein said metallic material is at least partially comprised of aluminum.
8 . The sill assembly as set forth in claim 1 wherein said sill deck extends along a longitudinal axis between a pair of longitudinal ends transverse to said first and second ends with said sill base extending along said first deck surface and coupled with said sill deck continuously between and to said pair of longitudinal ends for supporting said sill deck between and at said pair of longitudinal ends.
9 . The sill assembly as set forth in claim 2 wherein said pretreated layer and said structural layer are integral with one another.
10 . A method of manufacturing a sill assembly for use in a threshold system, with the sill assembly including a sill deck having first and second deck surfaces opposing one another and extending between first and second ends, and a sill base formed of a polymer and coupled with the sill deck along the first deck surface between the first and second ends of the sill deck; said method comprising the steps of:
providing the sill deck; and
depositing the polymer to form the sill base coupled with the sill deck along the first deck surface between the first and second ends of the sill deck.
