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, allows 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 for a rendered or tiled finish.

Hy-Rib® is primarily used in construction joint applications but it is also used to form wall, beam and column surfaces and slab soffits, where the formed surface will not be seen. It has also been used successfully for sprayed concrete applications.
