Product Advantages

of Pre-tentsioned Prestressed Beams

High quality Factory production ensures good and consistent quality production of concrete beams, with minimal supervision.
Shorter project leadtime Casting of beams and construction work on site are able to progress simultaneously, reducing overall project leadtime.
Ease of construction Precasting of beams are done at factory, hence no scaffolding/props/falsework are required over rivers or roads.
Cost saving Expensive falseworks otherwise required in certain situations are done away; shorter construction duration also means lower overall costs.
