A raisable goods-handling door of the type includes a flexible curtain capable of being wound up or of being folded up in the top portion of the door, said curtain being reinforced by at least one reinforcing or loading bar, the door being wherein the bar is made up of two half-bars that are disposed at the same level on the two faces of the curtain and, clamping provided so that the two edges of each half-bar are pressed against the curtain in sealed manner, thereby preventing dust or dirt from penetrating between either half-bar and the corresponding face of the curtain.
