What is the material of the wire grid generally used?

A wire grid is a product used to filter out the effect of stray rays on the film. Then many people are curious, what material is it made of?
According to the material of the grid, there are two forms: .
1. Commonly used wire grids—–the internal spacers are made of non-metallic materials, such as wood chips, paper
Sheets, plastics and other non-metallic low-density materials.
2. All-metal wire grid—–its internal spacer is metal material: aluminum sheet. Its high strength and resistance
Good wet performance.
The appearance of the wire grid is a flat plate with a thickness of 4~8mm. The internal structure is made up of many thin lead strips intersecting and arranging. The two lead strips are filled and positioned with an X-ray-transparent material and glued together. The filler can be wood, paper or aluminum sheets, etc. Finally, the top and bottom are encapsulated with thin aluminum plates to form a grid plate. From the cross-section, the arrangement direction of the lead strips of the filter plate will converge to one point. From the whole grid, there is a convergence line.
