UNSPSC 40181809: CS/alloy steel tube

Tube made of CS/alloy steel for boiler/superheater

UNSPSC 40181809 CS/alloy steel tube is a Commodity code covering raw steel materials—sheet metal, plate, and finished stock—that state and local governments procure for facility operations, maintenance, and construction projects. The code sees activity primarily from state agencies and municipal utilities soliciting raw materials and finished steel components through IFBs and sealed competitive bids. Recent opportunities show procurement of stainless steel sheets, mild steel plate, and raw metal stock for use in water treatment facilities, correctional institutions, and transportation infrastructure. The Texas Department of Criminal Justice appears as a repeat buyer, posting multiple IFBs for sheet metal and stainless steel materials to support facility operations and maintenance across the state prison system.

Texas dominates the recent solicitation activity under this code, with the Texas Department of Criminal Justice (IFB IW258604, due July 28, 2026, for sheet metal and metal plate; IFB IW240459 for stainless steel sheet 304L, 4' x 8', due January 29, 2026) and the City of Lavonia, Georgia (sealed bid for water treatment plant improvements including related steel materials, due May 26, 2026) representing the primary buying bodies. The Texas Department of Transportation and Texas Workforce Commission have also posted opportunities tagged to this code, though those solicitations appear focused on services rather than raw steel materials. State agencies and municipal utilities in Texas and Georgia constitute the active buyer base, with procurement activity concentrated in the first and second quarters of 2026. The issuing bodies typically require vendors to register on procurement portals (Bonfire for TDCJ), acknowledge bid amendments, and comply with applicable set-asides such as HUB participation goals or ESBD certification where designated.
