Bangladesh Steel Re-Rolling Mills (BSRM) is set to manufacture a new construction material named ‘Low Relaxation Prestressed Steel Strand (LRPC strand)’ in an attempt to cater to the Tk 3,000 crore market section which is dominated by imports.
The nation’s leading steel manufacturer invested a total of nearly Tk 1,000 crore to establish an LRPC strand manufacturing unit under its new concern BSRM Wires, based on the deputy managing director of BSRM, Tapan Sengupta. The strands are utilised in the prestressing of concrete for various kinds of construction work.
The LRPC strands are utilised 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 and viaducts, as well as railway sleepers.
Presently, there are a number of bridges, flyovers, and tunnels under construction where the LRPC strands are being utilised.
Sengupta stated that the country requires nearly 12,000 tonnes of LRPC strands per year while BSRM wires have a yearly manufacturing capacity of 30,000 tonnes.
The present market for LRPC strands is nearly Tk 3,000 crore yearly and will continue to increase for the next 20 years.
An LRPC strand manufacturing plant was established at Mirsarai in Chittagong as the steelmaker strives to capitalise on the impending construction boom in Bangladesh.
The Tk 500 crore project was implemented with 70 per cent bank financing and 30 per cent equity investment.
