Szemcsegrács

Szemcsegrács is a Hungarian term that translates roughly as “eye grid” or “mesh grid,” referring to a regular, planar network that forms a repeating pattern of openings. The concept covers both physical meshes and abstract lattice-like arrangements, characterized by a regular cell size, cell shape, and the thickness of the connecting strands.

The geometry of a szemcsegrács is defined by the shape of its openings (often square, rectangular, or diamond-shaped) and the spacing between adjacent openings. The material can be metal, plastic, fabric, wood, or composite, and the lattice can be produced by weaving, knitting, perforation, laser cutting, or additive manufacturing. The term is commonly used across fields to describe structures that are purposefully perforated or grid-like for functional reasons such as passage of air or liquids, light, or objects, as well as for aesthetic purposes.

Applications of szemcsegrács are diverse. In filtration and sieving, screens with specific opening sizes control flow and retention. In construction and architecture, mesh or grille-like elements provide shading, ventilation, or reinforcement. In textiles and fashion, woven or knitted eye-grid patterns create bulk materials with defined porosity and texture. In design and engineering, the term may describe perforated panels, screens, or lattice supports where regular openings influence mechanical properties.

Measurements commonly involve the size of the openings (szemnyílás) and the density of the grid (number of openings per unit length). The exact terminology and standards may vary by industry and application.
