Expanded mesh is a type of metal mesh that is created by cutting and stretching a metal sheet into a pattern of diamond-shaped holes. The process involves first punching a pattern of holes in the metal sheet, then stretching and pulling the sheet in different directions to create the diamond-shaped openings.

The result is a strong and durable mesh that is ideal for a range of applications, including fencing, security screens, walkways, and industrial grating.

Expanded mesh can be made from a variety of metals, including steel, aluminum, and stainless steel, and can be customized to suit specific design requirements. It offers excellent visibility, ventilation, and drainage, making it a versatile and cost-effective solution for many different projects.
