Door panel for overhead roll-up doors and a method for creating the same

A door panel for an overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening, the door panel having a first face, a second face, a top edge, and a bottom edge and further comprising:

• at least two sub-panels butt jointed together in a horizontal direction in a manner such that neither sub-panel overlaps the other;
• at least one strip of horizontal seaming material adhered over each horizontal butt joint, the at least one strip of horizontal seaming material being adhered over each horizontal butt joint horizontally across at least the first face of the door panel;
• and,
• at least one strip of vertical seaming material adhered vertically along at least one face of the door panel, the at least one strip of vertical seaming material extending from approximately the top edge of the door panel to approximately the bottom edge of the door panel, wherein the at least one strip of horizontal seaming material stops at a first edge of the at least one strip of vertical seaming material, and continues extending horizontally across at least the first face of the door panel from a second edge of the vertical seaming material so that a top face of the vertical seaming material is substantially co-planar with a top face of the horizontal seaming material.
