Abstract
Abstract This disclosure relates to a sheeting-plate formed of two cover plates joined by transversely extending webs wherein the webs are formed integral with at least one of the cover plates by being folded out of the plane thereof and are secured to the other cover plate by welding. The webs are notched to receive upstanding reinforcing members, and the cavities defined by the webs may be filled with a reinforcing plastics material.
