Nearly 250 jobs could be at risk as the firm reels from a drop in orders. Robinson had won a string of steelwork contracts on the now-ravaged BSF schools programme.
The BBC reported that the family-run company said a downturn in the industry and the impending retirement of its managing director had prompted the move.
A company spokesperson said it had entered into a 90-day consultation period with staff.
In a statement, the firm said: “The last two years have been extremely tough for the construction industry whilst also experiencing unprecedented challenging market conditions.
“There has been a steady downturn in demand for steel structures and the government has announced recent spending cuts.
“In particular across the Building Schools for the Future programme, which has resulted in the cancellation of numerous high-worth contracts.”
Robinson was formed in 1964 as S.Robinson and Sons (Engineers) Ltd and the current turnover is £40m
