The latest group financial results from Boalloy Holdings reveal that the bodybuilder and trailer manufacturer made a pre-tax profit of £456,000 on a £23m turnover during 2006.
The company was created as a vehicle to aid a management buyout of Boalloy Industries in July 2005 for more than £1.9m.
Northern Ireland-based steel fabrication business JMF acquired 100% of the shares of Boalloy Holdings in November last year.
According to Boalloy Holdings' directors, the buyout took place "at a time when market conditions were far from ideal" and they expected a period of difficult trading before volumes rose.
However, they say they were "delighted with the rapid growth in truck body sales", particularly through subsidiary Boalloy Fastruck.
