Hy-Rib is a specialized expanded metal sheet product engineered for use as permanent formwork in concrete applications. Its open mesh profile facilitates the flow of concrete slurry through the keyjoint, creating a robust mechanical key for subsequent pours. While primarily utilized for construction joint applications, Hy-Rib also proves valuable in scenarios such as wall, beam, column, and soffit slab construction, where the formed surface remains unseen.

The principal advantage of Hy-Rib lies in its substantial reduction of surface preparation. When concreting resumes on the other side of the formwork, the angled tangs become embedded, forming a sturdy mechanical bond. Consequently, Hy-Rib joints exhibit superior strength compared to traditional joints.

Hy-Rib is versatile and suitable for use in single-faced, double-faced, curved, lost formwork, or underwater settings, combining the strengths of steel and timber to provide reliable performance in conventional construction formwork.
