> Source: https://deviationcheck.com/divisions/05-metals/manufacturer-substitution/

The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.

## What to look for in Division 05 Metals

Structural steel specs name fabricators, joist manufacturers, and deck suppliers. Look for:
- Steel joist manufacturer substitutions (Vulcraft/Nucor, New Millennium, Canam)
- Metal deck manufacturer substitutions (Verco, Vulcraft, ASC Steel Deck, Consolidated Deck)
- Steel fabricator changes (must hold AISC certification for the work category)
- Shear stud manufacturer substitutions (Nelson, TRW)
- Expansion anchor and cast-in-place anchor manufacturer changes (Hilti, Simpson Strong-Tie, Powers)
- Ornamental metals fabricator changes

## Severity

Default grade: Blocker. Drops to a Note if the submittal attaches an or-equal approval letter from the architect of record.
