# Performance Specification Gap in Division 05 Metals submittals

> Source: https://deviationcheck.com/divisions/05-metals/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

## What to look for in Division 05 Metals

Key performance parameters in metals submittals:
- **Steel grade** (ASTM A992 Grade 50 for W-shapes, A36 for plates/angles, A500 Grade B/C for HSS, A53 for pipe)
- **Bolt grade** (ASTM F3125 Grade A325 vs A490, or metric equivalents)
- **Weld electrode classification** (E70XX for structural, E80XX for high-strength)
- **Steel joist load capacity** (total load TL and live load LL at specified span and spacing)
- **Metal deck gauge** (22ga, 20ga, 18ga, 16ga) and profile depth (1.5", 2", 3")
- **Composite deck capacity** (superimposed load at specified span, unshored vs shored)
- **Deflection limits** (L/240 total, L/360 live load, or as specified)
- **Fire rating** of steel assembly (spray fireproofing thickness, intumescent coating DFT)
- **Galvanizing thickness** (ASTM A123 for hot-dip, A153 for hardware, A653 for sheet)
- **Paint system DFT** (dry film thickness in mils per coat)
- **Moment connection capacity** (kip-ft at specified rotation)
- **Base plate thickness** and anchor rod diameter/embedment

## Severity

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.
