Steel Deck Detailer’s Guide
The Detailer's Essential Reference
Welcome to the interactive guide for SDI (Steel Deck Institute) standards. Designed for detailers and engineers to visualize profiles, calculate capacities, and specify fastening patterns.

Industry standard pattern for roof deck.
Detailer's Note: Sidelaps
Standard sidelap spacing is 30" O.C. Check engineer's specs for specific high-wind zones.
Fasteners
- #12/14 Screws
- 5/8" Puddle Welds
- PAF Nails
Watch For
- Burn-through
- Edge Distance
- Missing Laps
Materials & Finishes
Galvanized (G60/G90)
Zinc coating for corrosion resistance. G90 required for high-humidity or exterior overhangs.
Prime Painted
Gray primer for temporary protection. Not intended as a finish coat or for composite bond.
Yield Strength
Standard 33 ksi. Deep sections often 40-50 ksi. Grade E high-strength used for composite.
