Metal product ideas / looking for Benchmark

My family owns a large metalworking business. It is a subcontracting company, which means all our customers are big industrial customers. However, the idea of starting an e-commerce project appeals to me. Since we have a large machine park, we can process metal in every conceivable way (bending, laser cutting, welding, milling, turning, etc.). Now my question: Can you think of metal products that sell well on the Internet? To narrow it down a bit, we tend to make larger, coarse parts rather than small, intricate ones.
