Reinforcement arrangement for pulleys in roll-up metal doors, these pulleys being of the type having a general circular part on the cylindrical contour from which the door is wound, having at its center an orthogonal conduit in which the latter is threaded. Axis on which the rotation is made, and the current arrangement being characterized because each of the two faces defined in the circular part, has juxtaposed and joined at least one plate that reaches from the central conduit to the cylindrical contour, preventing the deformation so much of the circular part as well as the contour, and the joining preferably taking place by welding.
