Crittallhas been exporting for more than a century and in 2010 receives the Queen’s Award for Enterprise in International Trade in recognition of its achievements in the American market where it now ranks as the second largest supplier of steel windows.

Clients on the other side of the Atlantic include the Ivy League universities of Princeton and Yale, a prestigious apartment block facing Central Park in New York and, most recently, two leading boutique hotels, also in Manhattan.

Stuart Judge, Crittall’s managing director, said: “The Sunday Times Lloyds SME accolade is a further testament to the importance we attach to foreign markets for our world-beating products designed and manufactured here in Essex.

“In a further recognition of our commitment to export success we were delighted to be chosen by The Department for International Trade to host an ‘export bootcamp’ for Businesses in Essex at our Witham factory following a request from Witham MP Priti Patel. The workshop was held on the DIT’s mobile Export Hub and was a great success.”
