The firm, which specialises in door sets for non residential buildings, has a turnover of £37 million and made a pre-tax profit of £5.5 million in the year to April 2004.
SIG chief executive David Williams said: 'LS provides an important
extension to our existing commercial interiors product range. It concentrates on
the growth market of specialist door sets, especially where fire, acoustic and
high security performance requirements exist.'
He added that SIG's profits were set to be 30 per cent higher than last year following a strong trading performance.
