The award comes as the company will open a subsidiary in the USA next month to boost service for North American customers.
The Queen’s Awards scheme is marking its 50th anniversary this year and one category recognises development of UK companies in international trade.
Angela Musson-Smith, Detectamet’s managing director, said: “When my husband and I started our business in 2003 we could only dream of being honoured by an award such as this.
“Sean and I are so grateful to our staff, suppliers and local service companies who have helped us to fulfil our hopes and make our dreams come true.”
Detectamet said it distributes more than 500 products to more than 100 countries, some being used by food companies to protect from contamination.
The company designs, manufactures and distributes products made using metal and X-ray detectable plastics such as pens, protective clothing and stainless steel items.
If pieces of this plastic end up in the food they will be identified and rejected by the metal or X-ray inspection system.
