July 29 (Reuters) - Tyman Plc, a maker of window and door hardware, said underlying pretax profit jumped 83 percent for the first half, driven by a robust rebound in construction in Britain and North America.
The company, which also makes high-security locks and seals for windows and doors for residential and commercial markets, said its full-year expectations remained unchanged despite a strong pound against international currencies.
Underlying pretax profit for the six months ended June 30 rose to 17.2 million pounds ($29.2 million) from 9.4 million pounds a year earlier. Group revenue rose 35 percent to 167 million pounds.
