So what is Severfield's secret? For a start, the company is the UK's biggest player with 16 per cent of the market and no near rival. Its size means it is winning larger and increasingly international contracts with blue-chip players like Siemens - in the period, 27 per cent of core business sales were exports. And as a bigger player it can keep raw material costs low, buying in bulk from British Steel. Moreover, as the strong pound squeezes weaker exporters out, Severfield continues to take share.
Severfield's defining quality, though, is a ruthless attention to efficiency. Compared with the industry average of nine man hours taken to process a tonne of steel, Severfield can do the job in five. John Severs, MD, aims for four.
That is good news for margin prospects at Rowen. New production processes have already raised Rowen's returns from 1.6 per cent at acquisition to 5per cent.

The one black spot is lossmaking Manabo, which specialises in chain-mail gloves and knife washers to improve food hygiene. Escalating mad cow costs have, ironically, left customers with no money to spend on upgrading their food hygiene equipment. With legislation enforcing new hygiene standards looking remote, Manabo should be sold.
