Keystone supplies structural steel tube and pipe and stainless steel tubing for agriculture use; general fabrication; corral pipe and corral tube; fence pipe and fence tube, gate pipe and gate tube, and panel pipe and panel tube; race car fabrication as well as many other applications. We are an important link in the supply chain for many manufacturing operations in North America.

Customers come to Keystone for quality products, like new structural steel tube and pipe, which often outlast used material that has been taken out of service and re-purposed from another application. Our American-made tube and pipe has not been contaminated in the field and contains no concrete, plastic liners, varnish, or other materials that are sometimes found in recycled tubing. Keystone structural tube and pipe is also field corrosion- and erosion-free (walls have not cracked or thinned due to previous service).

Quick-turnaround service is available for pick-up or delivery at our fully stocked Sand Springs, OK and Oil City, PA locations.
