The tension rods are aluminum (no rusting), the springs are stainless steel, and the ends have white caps. When ordering tension rods you will need two for each shade. The rods fit through the sleeves at the top and the bottom of the screens. You may need supportive rods, depending on the length of the shade. You may also need supportive rods if the shade is going around a curve. Custom size tension rods are not returnable.
