Metal Building Materials Expanded Metal Mesh Rib Lath Price is a steel encasement stiffened by rigid ribs used in reinforced walls, ceilings, and floors. They are helical hooping
units of steel sheathing forms used in concrete, stucco and plaster. Hy-Rib products are a derivative of the "wings" used in the
patented Kahn System of reinforced concrete, invented by Julius Kahn in 1903. The products are made from a single plate of steel.
Hy-Rib products were used in concrete doors, ceilings, and roofs. It was also used in sidings, partitions and ceilings to
eliminate channels. Hy-Rib products were designed to take on plaster and cement to eliminate layout forms in the construction of
buildings. The steel sheet form would be embedded with plaster or cement directly and would flow into the lath surface to attach
itself to the steel and harden to secure the material into the steel.
