Even if it's cold-rolled, I don't believe half-inch square is rigid enough to prevent someone "beefy" from bending both ends upward slightly, rotating ninety degrees, and off come the covers. Remember, you have an annealed point at your weld spot.

Maybe 1/2" x 1" would be more effective?
Of course, it's just a "deterrent", and anyone who really wants them will get them.

Objective reached, mission accomplished!
