Stainless Steel Pipe. Stainless steel pipe is primarily used in
piping systems for the transport of fluids or gases.
We manufacture steel pipe from a steel alloy containing nickel as well as chromium, which give stainless steel its
corrosion-resistant properties.

electrical enclosures, auto molding and trim, wheel covers,
kitchen equipment, hose clamps, exhaust manifolds,stainless hardware, storage tanks, pressure vessels and piping.
