Prestressed beams are manufactured in various sizes and cross-sections:

I-beams: rectangular cross-section beams are mainly applied to roofs or inter-floor coverings as precast monolith structure with average span length up to 12 m. Beams usually have prestressed reinforcement wires or common reinforcement bars.
