1883 – 1910
In 1883 Paul Winn sets up the import/export house Paul Winn & Co. Ltd in London, which would later become Winn & Coales (Denso) Ltd.
The company started by exporting coke to Germany, and later expanded into importing starches and sugars. By 1900, the company was established at the heart of the commodities sector in Mark Lane and had expanded into trading items such as waxes and petroleum jelly.
1910 – 1920
Paul Winn’s son Eric Winn joins the company in 1910 and it diversifies to additionally trade in wall tiles and other building commodities.
In 1916 Frank B. Coales joins the company, with his section becoming known as Department ‘C’. Around this time the company also acquires an agency for miners’ lamps.
1920 – 1930
Paul Winn & Co. Ltd remains a private company. Alongside this The Barking Brassware Company, which manufactures pipes for plumbing and bathroom fittings, and P. Winn (Barking) Ltd, which makes Abbey Tiles, become public companies. This collective group of companies are the origin of Winn Industries Ltd.
In 1929, Winn & Coales secured a license from Germany to import and market Denso corrosion prevention products into the United Kingdom. The products proved to be hugely successful with the gas and water industries where it was used for the protection of pipes and fittings.
1930 – 1940
In 1933 Paul Winn appoints Frank Coales as his partner, forming Winn & Coales Ltd. The manufacture of Denso Tape (under license to Germany) begins in factory premises in Stepney. The new company takes over all of the activities of Department ‘C’, forming the origin of today’s company – Winn & Coales (Denso) Ltd.
In 1938, Beckenham-based Beney Lighters is acquired, adding utility lighters and precision tools to the company’s ever-growing list of products. The biggest selling line manufactured by Beney was the Economic Gas Lighter which was hung on the side of housewives’ gas cookers and was also used for lighting Bunsen burners in laboratories.
1940 – 1950
With the onset of World War Two in 1939, large quantities of Denso tape were purchased for the purpose of gas proofing rooms and repairing bomb damaged gas mains, as well as waterproofing military vehicles.
Following a ‘doodlebug’ flying bomb attack the company’s Head Office at Trinity Square, and many company records, were destroyed. Following this, the business moves its administration to the Beney Lighter premises in Beckenham.
Manufacturing demand begins to outstrip capacity, but the company is unable to expand to larger premises until after the war is over.
1950 – 1960
In 1950, the company moves to ‘Denso House’ in Chapel Road, West Norwood, under the chairmanship of Frank Coales who has taken over following the death of Paul Winn in 1946.
Customer demand continues to fuel the steady expansion of the Denso product range and products such as Coal Tar Tape are developed. A company research laboratory for product development is established.
In 1957, using knowledge and experience gained over the previous 25 years, a range of water and weatherproofing products aimed at the DIY market are launched under the Sylglas™ brand name.
1960 – 1970
In 1964, agents are appointed throughout the world to promote the expanding product range and partnerships are formed in Australia, New Zealand and South Africa. These partnerships provide the foundation of the present company’s worldwide network.
In 1965, David Winn – grandson of the founder, Paul Winn – joins the company and two years later is appointed Deputy Chairman.
1970 – 1980
The 1970s saw the introduction of an important addition to the Denso product range – a heavy-duty adhesive, cold-applied bitumen laminate tape for the external protection of large diameter buried steel pipelines. Fire resistant systems were also developed for use in oil refineries, railway tunnels and on offshore platforms.
The company was also still expanding rapidly, with subsidiary companies formed in the USA and Canada.
In 1979, the company celebrated the 50th anniversary of taking on the agency for Denso Petrolatum Tape, whilst a new laboratory and conference building was also erected and opened.

In 1986, Dr Keith Erskine, grandson of Frank Coales, was appointed a non-executive Director and the company purchased Protal Coatings. Protal is a well-established range of liquid coatings which complements the Denso range of tapes perfectly.
In 1989, Frank Coales celebrated his 100th birthday and entered the Guinness Book of Records for still actively working as Chairman at the time. That same year, Archco – Sprayglass Ltd and Rigidon Resistant Materials Ltd were purchased – both established suppliers and applicators of resistant linings for industrial tanks. The two companies later merge to form Archco-Rigidon Ltd.
1990 – 2000
Chairman Frank Coales dies age 102 in 1991 after 75 years with the company and is replaced by David Winn. At this time, the company had been trading for 112 years under only two Chairmen.

2000 – 2010
The decade starts with the export of a full range of products to China for the first time.
Demand for the UK’s new SeaShield 2000 FD system lead to numerous contracts around England, Wales and North America. Denso Steelcoat Systems were also regularly specified on offshore oil rigs, steel structures and pipework in process plants.
The Denso subsidiaries improve their market share, with record results in North America. Larger manufacturing facilities were built in the USA and new premises were acquired in Canada. A new Denso factory was also commissioned in South Africa.

In recent years, the company has achieved the latest ISO 14001:2015 standard, along with the ISO 9001:2015 for Quality Management too.
A long-standing desire to educate its customers in correct product application techniques was also achieved during this period with the building of a dedicated ‘free of charge’ training centre at the head office site in London. To underline its success, this facility has remained constantly in use ever since it was opened.
In 2019 the company celebrated 90 years of the manufacture and supply of corrosion prevention products.
