Steel & duct protection
Structural steel and ductwork.Calculated, not guessed.
Thickness and material quantities for spray, board and intumescent steel protection, and for spray or wrap duct protection, taken from published manufacturer assessments.
Structural steel
Every member.Every exposure.
- Members from the section database, or an entered section factor: Hp/A or ESA/M for spray, ESA/M for board, and A/V, Hp/A or ESA/M for intumescent
- Three- and four-sided exposure for I/H, RHS/SHS and CHS sections
- Fire period and critical temperature on every line
- Spray thickness, board thickness and sheets, or intumescent dry film thickness
- Pooled bags, sheets or packs, with waste
Ductwork
Every run.Every FRL.
- Rectangular ducts by width and height, with run length
- CAFCO 300 and MONOKOTE spray, or FyreWrap
- FRLs from 60/60/60 to 240/240/180
- Internal, external, both or mixed exposure, plus FyreWrap uses for kitchen, smoke and other exhaust, stair pressure relief and stair or other pressurisation
- Thickness or wrap layers, plus material quantities
From drawing to schedule
Measured on the drawing.Linked to the schedule.
Steel and duct items measured in Takeoffs transfer into these calculators after a preview. Calculated thickness flows back to colour members on the drawing, and linked rows stay in sync as the schedule changes.
