We thank you for your interest in our products. Below you find an overview of our standard deep engraved (milled - CNC) doorbells in brushed stainless steel. Since quality is our number one priority, we resolutely choose for high-quality stainless steel 316 (AISI 316 K320). All the sheets have a thickness of 3 mm. All doorbells have a fully stainless steel push button and can be mounted without any visible fixings (see our installation instructions for doorbells). When ordering, we must first make a preliminary layout, which we will relay mail. Upon approval, we take the production to.
