Armstrong PeakForm Exposed Grid β Material Take-off
Based on Armstrong PeakForm data: main bars (3600mm) at 1200mm centres, cross runners 1200mm at 600mm spacing, suspension points at 1200mm max centres along main bars, wall angle (3600mm) fixed at 450mm centres. Deflection limit 1/360 to AS/NZS 2785:2020. Light fittings, A/C fixtures etc. supported by the grid may need extra hangers; external areas or openings prone to wind uplift need down bracing. Check fixture weight limits and seismic design with Armstrong/TBS for the specific job.
Check spans before ordering. Hanger and framing spacings must comply with the Blueprint span tables for your board weight, wind region and building importance level (Blueprint Tables 3β18, pp.567β589). Tape & compound quantities are industry rules of thumb based on the ceiling face area (only the face layer is jointed). Fire-rated ceilings need paper tape with mastabase/mastalongset as a minimum (Β§7.3). Quantity estimate only, not a structural design.
Steel Stud Partition Wall β Material Take-off
Check the wall height tables before ordering β maximum height depends on stud size, gauge (BMT), spacing, lining and wind pressure (Blueprint Tables 2β13, pp.114β124; heights reduce for tiled walls). Each doorway adds 2 boxed jamb studs and a sill/head track allowance; opening framing for large or heavy doors needs structural design (Β§3.2). Tape & compound lines are industry rules of thumb, not Blueprint figures. Quantity estimate only β not a structural design.

Ratings shown as Structural / Integrity / Insulation in minutes ("β" = no structural adequacy component). Schematics are indicative cross-sections only β always open the page link for the tested system detail: exact board types, insulation requirements, framing limits, sound ratings and test report numbers. Systems marked "lined side only" or "from above/below only" are directional β check the fire comes from the tested side. Board substitutions per Β§2.3 (fireshield β multishield/impactshield/trurock of same or greater thickness).
