When a Cromer-based business received an order which had to be turned round quickly, it had no idea it was needed for a high-profile TV drama.

Structure-flex, which supplies flexible fabric products, was asked to produce two sets of lorry curtainsiders for a haulage company called Le Saux.

The firm learned that its client was in fact ITV detective drama The Level and the job was turned round in a little over a week to meet filming schedules.

The six-part drama, now under way on Fridays at 9pm, is a tense thriller starring Karla Crome as Detective Sergeant Nancy Devlin, whose exemplary police career masks a hidden attachment to shady businessman and drugs trafficker, Frank Le Saux, played by Philip Glenister.

Structure-flex managing director Paul Reeve said: 'When we were first approached to produce the lorry curtains for Le Saux we had no idea that they were going to appear in an ITV drama in which the plot centres around the life of a haulier so were very excited to learn that a product made by Structure-flex was going to take such a starring role.'

The Level is produced by BAFTA award-winning indie Hillbilly Television and includes an all-star cast.

Joining Karla Crome and Philip Glenister are Da Vinci's Demons Laura Haddock, Chasing Shadow's Noel Clarke, Downton Abbey's Robert James-Collier, EastEnders' Lindsey Coulson, Outlander's Gary Lewis, Doc Martin's Joe Absolom, Silent Witness' Amanda Burton, and BAFTA nominated Ruth Madeley.

Family-run firm Structure-flex, based on Holt Road, has been going for 46 years and won a Queen's Award for International Enterprise in 2013.
