Low Relaxation Prestressed Concrete Strands-Al-Ittefaq Steel

AL-FAISAL STEEL’s high-quality, low-relaxation prestressed concrete strands consist of helically laid wires spun together in the same direction. AL-FAISAL STEEL’s LRPC strand contains seven wires in a single LRPC strand.

LRPC strands are used in prestressed concrete girders for building roads, flyovers, river and railway bridges, prestressed concrete domes, hollow core slabs, steel beams and TT slabs, silos, hangars, aqueducts (waterways), viaducts and railway sleepers. By utilizing LRPC strands, you can achieve as much as a 10-percent reduction in the use of steel in construction. LRPC strands are also used where large spans are desirable, such as in the prestressed and post-tensioned Concrete Market for the construction of bridge beams, shopping centers, car parks and commercial buildings. AL-FAISAL STEEL’s PC strands are used extensively in prestressed and post-tensioned concrete structures.

PC strands consist of multiple wires spun together in the same direction. Super low relaxation PC strands can be used for either prestressing or post-tensioning of concrete. By reducing the required man-hours and saving on the amount of pillars, ducts, sheathings and wedges needed, there is a general reduction in the cost of the project.

AL-FAISAL STEEL’s low-relaxation prestressed concrete strands have the following benefits:

• Lower relaxation loss
• Higher proof load
• Higher breaking load
• Improved performance at high temperatures
• Higher resistance to fatigue and corrosion

Reducing the number of required structural parts significantly reduces the amount of cement used, helping boost a project’s viability.
