The firm said the increase was due to continuing high raw materials costs and “the need to set new, sustainable market levels in the New Year.”
Mick Maloney, Tata Steel commercial manager for sections, said: “Stock levels in the structural sections supply chain are low at present.
“We expect demand to improve in the New Year, because inventory will have to fill up ahead of the return of the construction season towards the end of Q1 2011.”
Tata is writing to its sections customers to inform them of the price increase.
