Query: not strong dumbbell's bar

My husband uses little heavy dumbbells.After using dumbbells, he keeps them on the holding bar.Holding bar is bending little bit because of it's weight.I think bar is not strong enough to hold heavy dumbbells.It should be redesigned strong but not heavy.Also dumbbell is not so great.Mine was delivered as broken condition.Amazon gave me a 10% credit but looks not good anyway.If I want to buy same, I will go to shopping center and try and buy them.
