Preforced plastic sheet, which is essentially constituted by two superimposed sheets of said material, especially polyethylene, supplied in continuous form and welded together by pressure and, preferably, by thermal or electrical action, between whose leaves is interspersed a reinforcement determined by zigzag threads, which intersect forming a regular or irregular grid that occupies practically all the useful width of the piece, the aforementioned threads being of an appropriate resistant material and being the same immobilized by virtue of the union itself rigid sheet components, which, thanks to such internal reinforcement, presents high mechanical qualities against the traction and tear reinforcements.
