Hy Rib
Description
Hy-Rib is an expanded metal sheet product, specifically developed for use as permanent formwork to concrete. The profile of the open mesh, in combination with the Hy-Rib tangs, allow the development of dense concrete nodules and indents on the face of the Hy-Rib, forming an enhanced mechanical key for the second phase pour. In the case of visible elements, the resulting Hy-Rib surface is suitable to receive a rendered or tiled finish.
Hy-Rib 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 Hy-Rib has been successfully used as permanent formwork on innumerable building & infrastructure projects, throughout the world.
Hy-Rib has an enviable portfolio of technical data. Independent bodies have undertaken full scale testing programmes to determine and verify Hy-Rib’s effectiveness in forming construction joints. The result is a product with well defined engineering properties, established formwork pressure characteristics and measured improvements to the joint performance. Hy-Rib is certified for use as permanent formwork by the British Board of Agrément (BBA).
The products is hot-dipped galvanized steel sheets. Because its meshes and U patterns, it has better anti-stress capability and forming flexibility than normal metal lath. This product has excellent engineering quality, construction joint 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 etc. asconcrete permanent assembly-free formwork.
REASONS TO USE HY-RIB
- Reduced risk of Hand & Arm vibration injury (white finger): product featured in HSE document – Vibration Solutions Ref HS (G) 170
- When Hy-Rib is used as vertical formwork, the resulting formwork pressure is significantly less than that developed with traditional forming materials, reducing the overall support requirement.
- Hy-Rib joint surfaces require minimal preparation prior to the next pour, with the exception of the rebar cover zones. It minimises the labour, mess and disposal requirements associated with scabbling, chemical retarders and jet washing.
- A correctly formed Hy-Rib joint outperforms traditionally prepared joints in shear and bond.
- Hy-Rib reduces the risk of trapped air and voids within the concrete.
- The range of narrower sheet widths improves site productivity and minimises wastage.
- Hy-Rib is a proven construction product with comprehensive technical data, manufactured by an established UK company.
