Steel Pipe & Fittings

Steel pipe provides the structural integrity required for utility casing, road and railroad crossings, bridge attachments, and industrial conduit applications where plastic alternatives can't handle the loading conditions. Galloway stocks steel pipe in both foreign and domestic sourcing across the full range of schedules from lightweight Schedule 5 through heavy-wall Schedule 160 and Extra Heavy (XH), in nominal sizes from 1/8" through 48". Galloway carries steel pipe from suppliers including Ironhed and Prime Conduit.
