FAQ

What work fits NAICS 333519?
  • Design and manufacture hot or cold rolling mill lines including roll stands, drives, gearboxes, and control housings delivered with factory acceptance testing and spare parts kits.
  • Supply roll grinders, roll resurfacing machines, and precision roll-handling equipment with documented calibration and dimensional tolerances.
  • Fabricate heavy-duty plate bending, straightening, or leveling machines to specified tonnage and roll geometry with operator training and maintenance documentation.
  • Deliver replacement major assemblies and spare parts packages for existing rolling mill installations, including technical drawings, parts lists, and recommended maintenance intervals.
When is NAICS 333519 a weak fit?
  • Metal forming or processing services: facilities that perform plate rolling, coil slitting, or metal forming as a service but do not manufacture the rolling or metalworking machinery itself.
  • General machine-tool manufacturing: producers of lathes, milling machines, or cutting tools whose primary products are machine tools rather than rolling or roll-processing equipment.
  • Installation or erection contractors only: firms that install or commission customer-supplied rolling mills but do not design or manufacture the machinery.
What solicitation language points to NAICS 333519?
  • RFP requires factory acceptance tests (FAT), mechanical and electrical drawings, run-off tests at specified throughput, and delivery of spare parts kits.
  • Scope specifies manufacture of roll stands, gearboxes, drive systems, and dimensional tolerances with material traceability and QA documentation.
  • Evaluation asks for past performance manufacturing heavy metalworking lines, evidence of quality management system, and detailed production lead-time schedules.
