01. What is expanded metal mesh?
Expanded Metal mesh is traditionally seen as a metal material with diamond shaped holes. Expanded Metal is produced by an expanding machine, which uses a pressured slitting and stretching process to transform solid metal sheets and coils into expanded mesh. Most types of metal, including precious and specially produced metals, can be expanded.
Expanded metal mesh products are produced from solid sheets or plates of carbon, galvanized steel and stainless steel, as well as aluminum and a variety of alloys of copper, nickel, silver, titanium and other metals. Because expanded metal is made from a solid sheet of metal, it can never unravel. The metal strands forming the open diamonds permit light, heat, air, liquids and sound to pass through – yet present a virtually impenetrable barrier to intruders. Expanded metal mesh is an extraordinary, versatile material – one with thousands of uses. Rhomboidal expanded metal is the most common used expanded metal pattern. Its diamond shape allows good air and light passage and gives an aesthetic appeal.

02. Expanded Metal Mesh Production Process
1. Sheets or coils or metal are fed into the expanding machine. A little metal can create a lot of mesh, adding value and saving resources and money.
2. Each machine is fitted with a unique "Knife", dedicated to a particular pattern. New patterns and knives can be created in-house for specific applications.
3. The machines are then programmed or manually controlled to ensure the metal is expanded to the exact specification. Rigorous quality checks are carried out to ensure product consistency throughout the expanding process.
4. Using the unique shearing and stretching process means very little waste is created. the metal is sheared and then stretched in a single process creating the apertures and therefore expanding the metal. The mesh is then either cut into sheets or wound onto coils ready for shipping or further processing.
