METAL PLATE FOR WIRE GRID, WIRE GRID, AND METHOD OF PRODUCING METAL PLATE FOR WIRE GRID

摘要

A metal plate (10) for a wire grid has a grid section constructed from longitudinal bar sections (11) extending longitudinally and lateral bar sections (12) orthogonal to the longitudinal bar sections (11). The metal plate (10) is attached to a frame body (20) to form the wire grid (100). The interval between the lateral bar sections (12) is equal to or greater than five times the interval between the longitudinal bar sections (11). The grid section can be formed not only in the grid pattern by the longitudinal bar sections (11) and the lateral bar sections (12) but also in a staggered pattern by the longitudinal bar sections (11) or the lateral bar sections (12).
