It would provide some mechanical protection, but not against piercing by screws/nails. Though durable, a nail or screw would go through it easily and into the cable[s] inside.
For mechanical protection against that sort of risk you would usually use steel conduit or trunking.
BTW if it's visible in trunking, why do you need protection against nails or screws?
