Stock-length (sticks)

type: stock_length

C/Z-sections, RHS, SHS, pipe — cuts bin-packed into real stick counts, offcut shown per bar.

cuts 2400+1800+1650 → 1 × 6000mm (150mm offcut)

Divisible (rolls & boxes)

type: divisible

Sheet, mesh, fasteners, sealant — totals divide by pack size and round up.

ceil(78.4 m ÷ 21.34 m/roll) → 4 rolls

Safety buffer

Add a set number of extra packs or sticks per rule — covers site waste and cutting error.

Per-itemcode rules

Each code sets its own stock length, pack size and buffer.

Offcut tracking

Offcut shown per stick and in total for each code — see where steel is wasted.
