A storage rack includes front and rear deck beams and C-shaped tie supports extending between the deck beams. Each tie support has a side wall, a top flange and a bottom flange. The top flange and bottom flange have front and rear ends and tabs extending downwardly therefrom. The top flange has a reinforcing rib. When assembled with the deck beams the front and rear ends of the top flange are seated on a support ledge of the deck beams with the tabs received into respective slots. Similarly, the front and rear ends of the bottom flange are seated on a lower leg of the front and rear deck beams with the tabs received into respective slots. The tie supports cooperate with the deck beams to limit the sagging of the decks, while also preventing outward twisting of the deck beams.
