The awards, which are in the International Trade category, are the most prestigious awards a UK based company can win. Representatives from both companies will be attending a Queen's Award reception at Buckingham Palace on 14 July.
Trimetals exports its products worldwide with its top markets being France, Japan, Germany, the US and Holland. The company is confident that it will achieve its target to double turnover over the next five years.
Strata Products has also been steadily building its export sales, with overseas earnings increasing by 132 per cent in the last three years, according to sales and marketing director Jay Ilsen.
"The majority of these sales have been into Northern Europe, mainly in France, Germany and the Benelux region but we have also had success in many other countries much further afield including Australia, Japan, South Korea and South Africa to name a few," Ilsen added.
Both companies cited membership of the Gardenex federation as a key part of their success.
Trimetals said membership gave it access to overseas market research and sales leads which helped drive export sales. Trimetals has also been a regular exhibitor in the Gardenex-organised pavilions that have exhibited at spoga+gafa in Cologne, and has attended six UK Trade and Investment missions to Japan and has exhibited its products at a number of shows in Tokyo and other major Japanese cities.
Strata's Ilsen said Gardenex had provided "invaluable support" at overseas trade shows such as spoga+gafa in Germany and the National Hardware Show in the USA.
"It is a great source of pride at Strata that the products which we make in our factory in Nottinghamshire are being shipped all over the world and that we are able to demonstrate that certain areas of British manufacturing are not only still alive and well but actually thriving and able to compete in a global market place.
"One of our attributes is to be able to develop good quality niche products such as our decorative garden planters and our large heavy duty storage trunks, which help differentiate ourselves in what is a crowded market."
Director general of Gardenex, Amanda Sizer Barrett commented: "We receive reports on a daily basis of export successes achieved by our member companies, and are confident that more firms in our sector will be recognised in future years. We are privileged to work with such entrepreneurial firms and to play a part to help them achieve success."
