Transportation & Transit

Transportation systems depend on durable, corrosion-resistant materials capable of withstanding decades of service, environmental exposure, vibration, and routine maintenance. Stainless steel is commonly used in rail vehicles, transit infrastructure, maintenance facilities, and support equipment because of its strength, longevity, and corrosion resistance.

Fabrication, welding, repairs, and refurbishment activities can introduce heat tint, embedded iron, and other surface contamination that reduce corrosion performance if not properly addressed. Passivation helps restore the protective chromium oxide layer that allows stainless steel to perform as intended throughout its service life.

Pure Source supports transportation contractors, railcar manufacturers, fabricators, maintenance providers, and transit agencies with passivation and surface treatment services for both new construction and refurbishment projects. We regularly process fabricated stainless steel assemblies, structural components, piping systems, and large welded assemblies requiring documented corrosion protection.

Our team understands the schedule pressures associated with transportation projects and maintenance programs. Whether supporting fabrication of new equipment or refurbishment of existing assets, we help ensure stainless steel systems are clean, corrosion-resistant, and ready for long-term service.
