Precast concrete beam

Semi-precast girders are units whose shape allows them to replace cast-in-situ floor girders, offering an improvement in terms of material quality and finish, as well as a reduced execution time and associated costs. They can be used together with self-supporting joists in the first phase of flooring execution. There are a variety of important geometries for this type of beams, ranging from nearly flat girders that do not hang below the floor, up to beams of great depth rectangular, L type, and inverted T that can handle very large loads and spans.
