Abstract

New door for domestic and industrial uses, essentially characterized by being constituted by two laminar pieces, the rear being of greater surface than the previous one to form a strip or flap on the vertical sides and on the upper part of the door, comprising the laminar piece previous, a square bending in all its sides with what is the thickness of the door, ending this double to square on the vertical and upper sides, with a lower fold outward, while in the lower, the lower fold as top, will be oriented inward arranging the back laminar piece of greater surface of a square bending with another descending fold that determine the thickness of the lanyard or flap, assembling the last descending fold of the back plate, on the last fold out of the anterior plate on its vertical and upper sides, while the lower part is free of a flap or flap, the extreme obleces of both plates anterior and posterior, are located contiguously, carrying the lower fold or any other suitable point of the door, a hole made, through which is injected under pressure, rigid polyurethane foam or any other material that meets similar conditions, filling in the door between its front and back plates including the hollow of the surrounding gables or flaps, forming a homogeneous block, whose internal pressure keeps the door formed without the need for welding or any other fixing means.
