Prestasi Concrete Sdn Bhd
Prestressing strands -
12.7mm dia. 7-wire super low relaxation strands, conforming to AS 1311:1987 are used.
Concrete strengths - 28-day cube strength ranging from 45 to 60N/mm2 depending on customers' specification.
Customization - Customized beam designs can also be done upon customers' request.
Beam lengths - Various lengths can be made depending on customers' spec., up to a max. of 30m, due to transport limitation.
Advantages of using Pre-tensioned 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.
