Wall Steel Estimate

Stud Count-

Total Steel (m)-

Weight (kg)-

Formula Breakdown:

Quick formula: Total wall LM = [Lw × ((1/S)+1) × Hw + Lw × Pr + Lw × Ew] × Ww

Variables: Lw=wall length, S=stud spacing (m), Hw=wall height, Pr=plate runs, Ew=openings/junction allowance, Ww=wall waste factor.

Studs: - × -m = -m

Plates: - runs × -m = -m

Base Framing: -m

Total: -m

Formula Breakdown:

Quick formula: Total floor LM = A × (Fs + Fa)

Variables: A=floor area, Fs=floor steel LM/m², Fa=support-condition adder LM/m².

Joists: - × -m = -m

Bearers: - × -m = -m

Weight (kg)-

Formula Breakdown:

Quick formulas: Truss LM = A × Rt × Pf × (1+Gb), Battens m = A × Rb × (1+Gb)

Variables: A=roof area, Rt=roof-type truss LM/m², Pf=pitch factor, Rb=batten m/m², Gb=global buffer %.

Trusses: - × -m = -m

Waste (10%): -m

Truss Total: -m
