STOCK FIT

Cladding panel end trim and joint order — panel stock length scenarios.

How does changing panel stock length affect cladding panel end trim and joint order when the other inputs stay fixed?

What this decision changes

Full required pieces must fit usable stock. Aggregate area or length alone cannot prove a feasible cut or roll allocation. Method basis: Count separate panel courses after user-specified end trimming, with joint gaps only between neighbouring panels. Usable panel = stock − 2 × end trim; panels/run = ceil((run + joint gap) / (usable panel + joint gap)).

The focus is selected panel stock length. All other shared inputs remain fixed for each evaluated range.

Usable panel = stock − 2 × end trim; panels/run = ceil((run + joint gap) / (usable panel + joint gap)).Cladding Panel End Trim and Joint Order Calculator

Keep the comparison within scope

Permitted orientation, complete-run requirements and reserved cut losses remain supplied inputs; sampled layouts do not promise a globally optimal cut plan.

Counts the arithmetic consequences of supplied specifications. Does not select construction systems, structural properties, fastening schedules, safe handling limits or code compliance.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
