RC Square Piles

POH YONG RC PILES

Poh Yong Tiles Industries Sdn Bhd, established since 1977 and has become a “Trusted Name In Concrete Products” throughout Sarawak and Sabah.

Poh Yong Pile (PYP) is well known for its high quality R/C piles which are manufactured under stringent quality control and workmanship.

Our team of highly skilled and professional staff ensures conformity and consistent products and emphasis on excellent services to our customers.

Features

Quality Assured Factory Production
PYP pies are manufactured under factory controlled with management and supervision by highly qualified professionals, thus ensuring the highest
quality product and reliability.

Wide Range Of Pile Size

PYP piles are produced in sizes ranging from 150mm to 300mm square with various load carrying capacities to suit different design criteria. This will allow the selection of the optimum and economical piling solutions to all foundation problems.

High Load Carrying Capacities

With use of high compressive strength concrete of more than 45 Mpa,
PYP piles allow for heavier driving conditions in hard soil strata and have higher load carrying capacity for more economical design of foundation.

Design and Material Specifications

: STANDARDS :; MS 1314: Part 3 & 6: 2004
: CONCRETE :; Grade 45 MPa complying with MS 523
: CEMENT :; Ordinary portland cement complying with MS 522
: AGGREGATES :; Conform to MS 29
: REINFORCEMENT :; High tensile deformed bars conform to MS 146

Production

PYP piles are manufactured under factory conditions and the layout of factory is designed with the key objectives of producing a high quality product at all times

PYP piles are cast in specially designed steel moulds that facilitate the accurate placing of steel reinforcement cages and joints. Pile lengths from 3 to 12 metres can be made in the same moulds to the same strict tolerances.

High strength concrete of more than 45 Mpa is mixed using state-of-art concrete batching plant which ensures consistency and uniformity in concrete mix.

Structural Capacity Calculation

Maximum Axial Capacity calculation is based on

Where:

: fcu =; Characteristic 28 day concrete cube strength is 45N/mm².
: Ac =; Cross-sectional area of concrete.
: fsc =; Allowable steel compressive stress 175N/mm² for high yield reinforcement.
: Asc =; Area of main steel reinforcement.
