We thank you for your interest in our products. Below you find an overview of our standard laser engraved 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.
