All steels, aluminums, and even plastics show springback on release through the bending forces. Springback is the discharge of elastic strain and is particularly associated on to the fabric yield power.

Getting no exposed fixed components suggests the fasteners aren’t topic to weathering, humidity, wind, or other stresses which can split them down as time passes.
