All stainless steel tanks are pickled and passivated prior to delivery. We can also carry out an internal or external polishing if requested. We can check if the requirements are met by means of roughness measurement. After polishing, an additional treatment by electro polishing is possible. If the finishing is because of aesthetic reasons, glass bead blasting can be an alternative.
Carbon steel parts can be sandblasted and painted, according to your specification. For structural steel, galvanization is often used.
