At Groël, we blend Italian artisanal tradition and craftsmanship with advanced technology. We focus on meeting the needs of each project, which is why we offer bespoke designs and finish customization. Although we say we are “made in Italy,” we are truly “made with heart.”
We use solid brass in our manufacturing process, involving the meticulous development of molds, brass stamping at 800°C with a force of 975 tons, and specialized machinery capable of producing 150 pieces per hour. Our secret lies in our polishing method, with manual adjustments to ensure the excellence and smoothness of every product. We prioritize quality and respect for the environment at every stage of the creation of our products.
