  • Strengthened automatic sliding door
    Patent number: 11448003
    Abstract: Disclosed is a vertical profile for an automated sliding door. The profile is formed by front and rear walls connected by nose and tail walls. The nose and tail walls are thicker than the front and rear walls to provide enhanced resistance to deflection in the through-door direction. The walls are formed as an aluminum extrusion. The arrangement and thickness of the walls provides strength sufficient to withstand high wind loads without the installation of reinforcing members. Fillets may be provided where the walls are joined to lessen the tendency for the nose and tail walls deflect, further strengthen the profile.
