Calculation Methodology

Geometry

Square woven calculations use pitch = 25.4 / mesh count, aperture = pitch − nominal wire diameter, and open area = (aperture / pitch)². Rectangular open area multiplies the clear-opening ratio in each direction.

Mass

Mass estimates use nominal wire cross-sectional area, nominal wire length per unit area and the selected material density. Weave crimp, coatings, wire tolerance and fabrication can change delivered mass.

Revision control

Reference data records its type, source note and review date. Contract requirements must cite the relevant standard edition and supplier confirmation.

Dimensional conventions

All woven square-mesh formulas use nominal round-wire diameter and openings per linear inch unless the page says otherwise. Metric conversion uses exactly 25.4 millimetres per inch and 1,000 micrometres per millimetre. Rectangular calculations retain separate axes.

Validation and revision

Calculator test cases cover known aperture, open-area and mass relationships. Content and reference records keep reviewed dates. When a source standard changes, the scope and edition must be rechecked before its requirements are quoted for a contract.
