    Assumption

    The model uses theoretical sharp-corner geometry and material density from the current canonical material record.

    • Material density1lvl.thermal.materials · sp50-m1-245
    • Normative rolled-section mass and radiinot applied

    The result uses theoretical sharp-corner geometry. Normative section accuracy and table references require separate verification.

    What is calculated

    Core determines the section area, volume, mass 1 m or blank, total mass, physical perimeter, lateral surfaces, end faces, selected paint area and coating quantity including waste.

    Limitations

    This is a theoretical sharp-corner model. Bending radii, normative assortment mass, weld metal, holes, bolts and cutting optimization are not included.
