Precast concrete columns and beams provide advantages in designing buildings for shopping malls, schools, warehouse etc. Long span precast columns and beams provide benefits for large open area structure. Precast beams can be designed and produced using ordinary reinforced concrete or prestressed concrete. Precast components are delivered by trailers to the erection site for installation. 

Precast columns are produced in different sizes and shapes. Rectangular column size varies from 300mm to 600 x 600mm (or as per Structural Design Requirements) Precast columns are fixed to the foundations with pockets, projecting reinforcing bars or holding down bolts, the first solutions is mainly used for foundations of good soil; the second and third in the case of foundation piles.
