so, on this website at least, it would be: gietijzeren deksel niet gekneveld = cast iron cover
stalen deksel gekneveld = lockable galvanised steel cover

It may be necessary to know the exact function of this 'geknevelde deksel'.

Some are 'sealed manhole covers' in order to prevent to prevent odour nuisance, for instance.
