摘要

Natural plasterboard with reinforced fibers of unequal continuous shells on its four edges for continuous ceilings and partitions. The galces that the plate arranges for its geometry and dimensions form a parapast. The parapasta is formed by fitting the projecting gutters and the hidden girders, thus facilitating the filling of the joint. (Machine-translation by Google Translate, not legally binding)
