The information above is provided as a guideline. SFI is a fabricator of custom stainless steel equipment and we are not limited to these materials and finishes. We use a small amount of carbon steel in our facility for components such as legs, skirts, saddles, clad-flanges, ladders, handrails, fixtures, etc. Under certain circumstances, we will also erect a carbon steel tank in the field. To provide the cleanest possible environment, our electropolished vessels are built, electropolished, and shipped in their own production bay that is separated from the rest of the plant.
