Low relaxation PC strands (LRPC) are used in pre stressing of concrete for construction of various types of structures ( Road, River, Railway Bridges and Flyovers, Atomic reactor domes, Slabs, Silos, Hangers, Aqueducts, High rise buildings, Viaducts and Railway sleepers).

Pre-stressed concrete strand (PC strand) is a high-grade, low-relaxation, 7-strand steel cord used in the reinforcement and strengthening of pre-stressed concrete structures. Because it is used in critical applications, this strand consists of high-carbon steel with a high tensile strength, manufactured to the highest quality standards to ensure its durability. PC strand is available in several different thicknesses, ranging between .25 inches and .6 inches in diameter.

PC strand is widely used in prestressed concrete structure (both pre-tensioning and post tensioning). Its application is so wide that hardly any prestressed concrete structure is constructed without it. Bridges, high-rise buildings, industrial facilities, warehouses, stadiums, sport complexes, containment tanks, airports, seaports, train stations, railways, subways, monorails, tunnels, dams, reservoirs, above and underground mining operations, foundations etc. are just some of the applications where strand is used.

Low Relaxation PC Strand is renowned for its high quality and reliability. Our ability to meet numerous international standards like ASTM A416, BS 5896, JIS G3536, AS/NZS 4672.1, EN 10138 etc. has made us the preferred supplier

PC strand goes through a series of stringent tests to meet clients’ demand. Mechanical, Break Strength, Metallurgy, Chemical Analysis, Cross Section Magnification, Relaxation, Corrosive Environment, etc. are just some of the tests that we conduct to ensure clients’ get nothing but the best product from us. The standard geometric properties of each coil of PC strand is also tested to guarantee our quality standard.

One area to highlight is the Relaxation Test in a temperature controlled environment. The average result of our relaxation values is about 1.5% after 1000 hours for a 70% Breaking Load. And 2.2% - 2.5% for a 80% Breaking Load. This is way above the international standards around the world.

We also conduct Bond Strength and Transmission Length tests regularly. fib (Fédération internationale du béton / International Federation for Structural Concrete) and PTI (Post-Tensioning Institute, USA) has their own version of deflected tensile test, also known as ‘one pin test’. The test assesses the strand for tensile strength when stressed around a pin. We also committed to conduct such tests internally to prove that our strand is suitable for multi-axial stressing applications.

Stay Cable (bridge cable) strand has to endure a stringent 2 million cyclic Fatigue Test. And PC strand is well positioned to ride through this rigorous test with ease.

Also capable of producing galvanized strand, PE coated strand & epoxy-coated strand for various applications. The polymer grade used is designed for

Good chemical stability
High impact resistance
High rigidity
High resistance to creep
Resistance to rough abrasion
Stable at high temperatures

PC strand is packaged into a standard coil of 3 tonnes (other coil weight available as well) with protective wrapping for long shipments duration. Normally palletized and placed as eye-to-sky (possible for sys-to-side too). Additional corrosion protection can be applied on request. Test lengths may be packaged outside the strapping for easy access, or may be cut off and wrapped separately with individual pack identity labels and then shipped inside the eye of the pack. Hence clients can be assured that the PC strand they received is in good and working condition.

Being an end user ourselves in post tensioning work or ( projects, we definitely know what it takes to produce good quality PC strand to meet tomorrow’s engineering challenges.

Prestressed Concrete Wire and Strand (PC) strands are the most used materials to introduce prestress in a Pre-Stressed Concrete (PSC) structure. However, it is difficult to evaluate the final prestress force of the PC strand after prestressing or its residual prestress force after completion of the structure on site. This impossibility to assess eventual loss of prestress of the PC strand has resulted in a number of serious accidents and even in the collapse of several structures. This situation stresses the necessity to maintain the prestress force residual or after prestressing for the evaluation of the health of the concrete structure throughout its lifespan. Recently, several researchers have studied methods enabling one to verify the prestress force by inserting an optical fiber sensor inside the strand but failed to provide simple techniques for the fabrication of these devices to fulfill measurement performance from the design prestress to failure. Moreover, these methods require the additional installation of electrical resistance strain gages, displacement sensors and load cells on the outer surface of the structure for long-term precise measurement. This paper proposes a method enabling one to evaluate precisely and effectively the prestress force of the PC strand and intends to verify the applicability of the proposed method on actual concrete structures. To that end, an innovative PC strand is developed by embedding a Fiber Bragg Grating (FBG) sensor in the core wire of the PC strand so as to enable short term as well as long term monitoring. The measurement performance of the developed strand is then evaluated experimentally and the reliability of the monitoring data is assessed.
