Metal bed slatts (Shipley, BD18)

I have approx. 20 metal slatts after dismantling a bed, they are basically hollow metal tubes, length 95.5cm, diameter with plastic end cap on 2cm, and without end cap 1.5cm. Please let me know if they are any good for anything. Might do if you have a child that thinks it's bed is a trampoline ! Please leave a contact number if requesting. Thanks
