This research proposes new metal structural elements based on metamaterials as a replacement of conventional enforcement bars, which reduce metal consumption and increase stiffness and strength. Modern manufacturing machines based on lasers has a capability of fast one-side welding. This type of machines are standard now, what makes this procedure fast and cheap. Another aspect of the nowadays usage of metamaterials for construction works is the possibility to model them with all small details. Ten or twenty years ago modelling of numerous small elements covered by concreate was too expensive, even for one slab not to mention the whole building or a bridge. This work demonstrates one variant of metal reinforcement of concreate plate based on pyramid type elements. This type of pyramid reinforcements was inspired by the analysis of topology optimization of maximum stiffness of structure in case of bending. It was shown numerically, that under condition of three point bending such kind of plate has up to two times higher strength capabilities then conventional plate with equivalent metal consumption.
