Hello everyone, I have the common problem that the shelves of my Billy bookcase bend under the weight of the books. The wood has already started to sag a bit, which doesn’t make it any more stable. I want to increase the load-bearing capacity of the shelves to prevent further sagging. Does anyone have experience with how to reinforce the shelves or if there might be alternatives without having to buy completely new shelves? I’m open to any ideas, whether reinforcements, supports, or other methods. Thanks!
Thanks for the previous suggestions. The idea of using metal brackets and profiles sounds good. Does anyone have experience with which type of aluminum profiles work best? Does it need to be a U-profile, or are half-round rods sufficient? And what is the best way to attach them without damaging the wood? I want to minimize visible screws or unsightly fastenings.
Hello! I would like to add: In addition to metal profiles, the shelves can also be reinforced with precisely fitted wooden strips. It is important that the strips are glued and screwed at least on the front edge or even in the middle to minimize sagging. To avoid visual impact, I always use wood-colored strips or hide the screws under decorations.

For increasing load capacity, a U-profile is the most effective because it provides greater stiffness and acts like a small beam. Semi-cylindrical rods are usually too flexible to effectively prevent bending.gadalu schrieb:
Half-round rods are usually too flexible... That doesn’t surprise me – half-round rods are mostly decorative, not load-bearing reinforcements. For real stability, it’s better to switch to solid wood right away or completely remove these sagging floors. What’s the point of the best reinforcement if in the end you still keep the cheapest-looking result?As an addition: For those who do not want to visually alter the shelf, thin spring steel strips or similar tension profiles can be used. These are installed at the bottom, and the tension creates a counterforce against bending. This is an elegant solution to minimize bending without the effort of large constructions.
