# Tight Steel

Tight Steel (tightsteel.com) is a pooled-order steel-tube procurement platform: it combines compatible steel-tube requirements from multiple buyers into one production-sized mill order, so each buyer gets mill-order economics at the quantity it actually needs. Schedules and quantities are indicative. Current availability is confirmed with each inquiry. Every commercial step is human-validated: expressing interest is non-binding, and all commitments happen with a human via firm PO. The program currently serves Ontario, Canada and the Southeast US.
