Sheffield City Region’s biggest company, SIG, remains in the top spot for the 12th year - as The Star prepares to publish its Top 100 survey on Wednesday.
The insulation giant, based on Sheffield Business Park, has a turnover of £2.7bn, putting it far ahead of the next biggest company, lead specialist Eco-Bat Technologies of Matlock.
The Top 100 is an unmissable, annual analysis of the biggest firms in the region. The figures, compiled by Sheffield accountants BHP, show total turnover across all Top 100 companies has grown by four per cent in the last year.
Pre-tax profits have fallen 39 per cent. But total employee numbers have grown by four per cent, to more than 81,000 people.
The table reads like a ‘Who’s Who’ of top firms including Wilko Retail, at number three, based in Worksop and employs more than 20,000 people.
DFS furniture of Doncaster, Outokumpu Stainless of Sheffield and Lakeside 1 - better known as Keepmoat - housing company are all in the top 10.
The list includes some recent success stories including Strata Homes, Ancon and Naylor Industries, which are in after a big boost in performance.
Sheffield firm Pressure Technologies is also new after a steady rise through the ranks in previous years.
Big employers - Maplin, Polypipe and A4E are all high up again.
But it is SIG which dominates. The company - which employs 450 at three offices in the city - distributes products to the building trade including insulation, roofing and interior walls.
Starting out in Sheffield in 1957, it has grown into one of the biggest players in Europe and has a reputation for snapping up rivals - it has bought seven companies this year alone.
Some £200m has been set aside for further acquisitions over the next three years.
It is also building a multi-million pound website and developing off-site manufacturing - where single room apartments are made in a factory - which is a “hot subject” , according to boss Stuart Mitchell.
