What is Prestressed Beam?
Prestressed beams are substantially compressed during its fabrication which strengthens it against tensile forces which will exist when in service This compression is due to the tensioning of high-strength “tendons” placed inside the concrete volume to enhance structural efficiency of concrete which results in improved structural capacity and/or serviceability compared with conventionally reinforced concrete in many situations.
What are the advantages of Prestressed Beam?
- They permit use of larger spans even when heavy loads are encountered.
- They are structurally eﬃcient with exposed natural finish.
- They do not require propping and can be loaded immediately after erection.
- They undergo lesser deflections making them more stiﬀer.
- They have good torsional strength.
- They permit less structural depths, increasing the space available.
- Best used for Horizontal Structural Framework.
Maximum size of the beam – Width 1250mm x Height 1000mm
