Unlikely but could this be aircraft related ?

This frame work is on the dump belonging to Armstrong Whitworths (and suceeding firms )dumping grond on the banks of the river Sowe at Whitley Coventry.thin and flexible it is of a light met al that shows no signs of corrosion.

Are there rivets at the intersections of the horizontal and vertical elements?
Also looks like a separate strip along the bottom edge?

The strip is a narrow hinge which precludes it being blanks and it has no rivets at its intersections it is thin as a tobacco tin and bent with no effort when i unbent it from being bent double. At first i unrealistically hoped it might be an airleron or some such from a Siskin but i very much doubt it it seems too flimsy at the very least.
