Ribbed mesh lath is a high tensile metal lath stiffened by the longitudinal V ribs. Metal rib lath makes idea plaster base and reinforcement for all types of walls,ceilings, partitions and fireproofing of steel beam,and columns. The steel sheet form would be embedded with plaster or cement directly and would flow into the lath surface to attach itself to the reinforcing steel and harden to secure the material into the steel.
High rib mesh 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. High ribbed metal lath is primarily used in construction joint applications but it is also used to form wall, beam & column surfaces and slabs soffits, where the formed surface will not be seen. For over 80 years , throughout the world.
Diamond metal lathing is ideal for fireproofing structure constructions:
The uniform diamond opening and large open area provide a superior substrate for bonding of cementitious fireproof materials;
Rigid and flat sheets, bendable for box and contour design;
Square ends and smooth parallel edges on the sides for fast and easy handling;
Minimum stress cracks by maintaining consistent material depth.
Benefits using rib lath formworks:
The mesh lath becomes embedded easily with the concrete in buildings;
Metal ribbed lath remains strong in bonding and shearing and other forming;
Easy to cut and form to plaster work;
Providing ample keying for scratch coat;
Good mechanical performance, with less lateral pressure;
Concrete pouring process is easy seen and under control;
Light weight, easy to transport and install;
Optimization of process,increase the shear inerface.
Rib lathing products are now popularly used in following:
Concrete doors, ceilings, and roofs;
Sidings, partitions and ceilings to eliminate channels;
Plaster and cement in the construction of buildings;
Firewall construction;
Permanent building external walls;
Landscape sculpture, and other special engineering;
Slope protection, earth embankment engineering, etc.
Fixing and Installation of Rib Lath:
Fastener placement should be arranged for ideal furring;
Self furring rib lath used over solid surfaces shall be furred approximately ¼ inch away from the wall to allow for the proper stucco keying behind;
Self-Furred Metal Lath is secured to masonry surfaces with hardened concrete nails and power driven fasteners at the furring dimples;
Paper backed lath is often used in this type of application as a bond breaker.
