The traditional stainless steel sheet is industrially produced and marked with the factory stamp. These stamps are used to trace and prove the origin of the sheet. The sheet marking states the manufacturer’s name, which heat number and coil number apply, the thickness of the sheet metal, which standard the sheet complies with, the material number and the corresponding AISI number. This data matches the stainless steel sheet’s certificate. For industrial and construction purposes it is crucial that sheets are traceable in such a way. Aesthetically, this is of course not desirable, since this stamp is on the visible side.
It is possible to avoid having these markings by using polished/brushed/sanded sheets instead. If aesthetics are important, please state this in the quotation request or order, and we will examine your project to determine which material or which post-treatment is the most appropriate.
