Expanded sheetis a type of sheet metal that has been cut and stretched to form a regular pattern of diamond or square-shaped openings. It is created by making slits in a metal sheet and then stretching (expanding) it, resulting in a mesh-like structure that is lightweight yet strong.

Types of Expanded Mesh:
1. Standard Expanded Metal Mesh – Made from carbon steel, stainless steel, or aluminum, with diamond-shaped openings.
2. Flattened Expanded Mesh – Rolled after expansion to create a smooth, flat surface.
3. Micro Expanded Mesh – Features very small openings for fine filtration or screening.
4. Decorative Expanded Mesh– Used in architectural designs, with custom patterns.
