Reference excerpt

Severfield plc is a York based structural steel contractor. By turnover it is the largest in the UK, with a capacity of 130,000 tons per year, and a further 20,000 tons in the EU. Landmark works include London's 2012 Olympic Stadium, The Shard, Wimbledon Centre Court roof, Emirates Stadium and Paris Philharmonic Hall. The firm has acquired businesses across structural steel market sectors within the UK and EU, and it participates with JSW Group in a Mumbai based joint venture that fabricates 100,000 tons of structural steel per annum. Severfield owns 50% of Construction Metal Forming Ltd which in 2023, claimed to be the UK's largest supplier of steel decking.

History The business was founded in 1978 as a partnership named Severfield-Reeve; moved to Dalton in 1980, and incorporated as Severfield Reeve Structural Engineers Ltd in 1983. As a public company it was known from 1988 to 1999 as Severfield-Reeve plc; from 1999 to 2014 as Severfield-Rowen plc, and then adopted its current title.

Listings In July 1988, Severfield-Reeve plc was quoted on the Unlisted Securities Market, then moved up to the London Stock Exchange on 8 June 1995. As of 2022, Severfield plc is a component of the FTSE SmallCap Index.

Acquisitions and new businesses

Steel (UK) Ltd and Steel UK Ltd In 1991, Severfield Reeve acquired 80% of steel trading business, Steel (UK) Ltd and bought out the remaining minority shareholdings in 2009. The company ceased trading in 2002; was renamed Stable Move Ltd in 2005, and dissolved in 2013 owing £1,161,732 to Severfield plc and eliminating shareholder value. In 2006, Severfield established Steel UK Ltd as a 50% joint venture with Sheffield based steel stockholder Murray Metals Group Ltd to negotiate steel purchase prices for both partners. The company had been incorporated in 2005 as Stable Move Ltd. Severfield and Murray bought steel at prices agreed with suppliers by Steel UK and the company did not trade itself. The joint venture was dissolved in 2013.

Manabo In 1995, Severfield's meat processing safety equipment subsidiary Manabo (UK) Ltd began trading. Initially the business was a 75% joint venture with the original technology developer but in 1996, Severfield Reeve bought out all remaining minority shareholdings. The established Scandinavian distributor for Manabo's products agreed to purchase from the new company. Manabo manufactured at sites around Thirsk and from 1997, operated a chain mail glove factory in Bataszek, Hungary. Such was the anticipated transformation of the structural steel business that by 1997, The Times described Severfield as a "specialist engineer and supplier of equipment for the meat and poultry processing industry". However in the same year, company founder John Severs blamed Manabo's six monthly £902,000 losses on the meat industry being "reluctant to change its ways in health and hygiene".The glove business and company were sold in 2000 after a further £2 million loss in 1998, and asset write-down of £2.8 million in 1999.

Severfield Reeve Projects Ltd In 1991, subsidiary Severfield Reeve Projects Ltd was incorporated, initially to carry out construction at Severfield's plants. It began to undertake main contracting for others in 1997.

Severfield Reeve Projects diversified into house building in 2002, purchasing, on its own account, a site in Bagby for two traditional, five bedroom dwellings with 1 acre (0.40 ha) gardens. In 2008, it launched a property investment division with the purchase of distribution warehouses from Royal Mail and the RNLI for £7.1 million. The value of the initial investments was written down by £2.1 million in 2009. New projects and investments by Severfield Reeve Projects Ltd stopped in 2009, and it closed in 2011.

Kennedy Watts Partnership Ltd In 1999, Severfield purchased 25.1% of Sheffield based design bureau Kennedy Watts Partnership Ltd for £464,000 in shares and cash. The shareholding was restructured in 2008 so that it was held through an intermediary, Last Exit Ltd. Kennedy Watts Partnership Ltd was placed into administration in 2013; into liquidation in 2014, and dissolved in 2016 with a deficit to creditors of £292,000 and elimination of all shareholder stakes.

Deck riders In 2006, Severfield patented a craned or self climbing work platform that attaches to steelwork at height, and mounts its own powered access platform. The apparatus was invented to assist erection of steel structures where conditions are not suitable for safe operation of conventional access equipment. In 2009, the work platform project was abandoned and £2.4 million development costs written off. Severfield went on to develop 'deck rider' static base boom lifts with access platform manufacturer Niftylift. These can be repositioned by crane onto buildings under construction to sit in the steel decking. By 2009, they had been used on Severfield's Shard and Heron Tower sites facilitating safe erection speeds of a storey every seven days - without waiting for concrete floors to set. By 2011, Severfield had purchased 20 of the machines. As of 2025, deck riders are commercially available.

Controversies

Job losses In April 2025, Diana Armstrong, Member of the Legislative Assembly for Fermanagh and South Tyrone expressed concern about job losses at Severfield's Ballinamallard business. After a profit warning, Severfield's CEO had also agreed to leave the company.

Worked examples

Example 1 — a first encounter with Severfield

Start with the simplest possible case. Write down what Severfield claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Severfield before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Severfield ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Severfield

In research: Severfield appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Severfield in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Severfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1978 establishments in England, Companies based in York, Companies established in the 20th century, so understanding it makes those chapters shorter.
In everyday life: Look for Severfield outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
