METEX Hy-Rib Lath is an expanded metal sheet product specifically developed for use as permanent formwork to concrete. Hy-Rib is heavier and stronger than Rib-Lath and is widely used as a combined shuttering and reinforcement for concrete, eliminating the need for close boarded shuttering.
Hy Rib Lath has excellent engineering quality, construction security and widely used in tunnels bridges, valve basement systems, sewage systems, subways, retaining walls, nuclear power plants, shipyards, water pools and marine engineering works and high rise building projects and non-regular or bending pattern as concrete permanent assembly-free form work.

Lath should be fixed with apexes of ribs against the wall, edge ribs of sheets nesting into each other should be wire-tied every 15cm and ends of sheets should be lapped not less than 2.5cm and nesting ribs securely tied together.
Hy Rib ① is nailed to angular or profiled stiffening wood beams ②. Ribs should not be damaged or deformed during fixing. The closed ribs points towards the first concreting section since the ribs are exposed to the greater pressure. The ribs are placed cross to the stiffening wood beams.
Hy Rib requires the same concrete covering as reinforcing steel. In order to maintain the prescribed concrete covering timber rails ③ are nailed to the upper and lower sides of the construction unit as range spacers and to the stiffening woods beams.
The stiffening wood beams ② are nailed to the sheathing and held by wooden ledges ④, which are propped against the existing reinforcement.
