Improvements introduced in the manufacture of tubular flat bed bases, characterized in that they are constituted by a frame within a same plane, whose heads and stringers are constructed based on cold profiles joined at their ends by miter welding, which results in a perfect solidification and texture, and there can be no deformation since such profiles are hollow.
