How are Double T-Beams made?

Double T-beams, also known as double tee beams, are precast concrete elements typically used in flooring systems. They are manufactured by pouring concrete into a mold that shapes the beams into a T-profile with two parallel flanges and a central web. Once the concrete has cured, the beams are demolded and can be reinforced with steel for added strength. Finally, they are transported to the construction site for installation.
