Hy Ribbed Lath

Hy Rib Lath, also known as Hy Rib formwork, 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 Formwork is primarily used in construction joint applications but it is also used to form wall, beam and column surfaces and slabs soffits, where the formed surface will not be seen.

Application of Hy Rib Lath

● Large-scale construction and civil engineering, earth engineering, such as construction joints, independent foundation ground beams, raft foundations, retaining walls.

● Sewerage works, subways, MRT systems, nuclear power plants, docks, foundations and bridge decks.

● Irregular or curved surface modeling, high-rise buildings, marine engineering and other major projects can be used as the best wall material for reinforced concrete permanent formwork.

● RC structure or H steel structure exterior wall

● Retaining wall (all arc-shaped walls)

● Fences, tunnels, bridges

● Dams, storage tanks

Advantage of Hy Rib Lath

◆ Reduced risk of Hand and Arm vibration injury (white finger): product featured in HSE document.

◆ When Hy Rib Formwork 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 minimizes the labor, 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 Formwork reduces the risk of trapped air and voids within the concrete.

◆The range of narrower sheet widths improves site productivity and minimizes wastage.
