Steel Expanded Metal With Raised & Flattened Type
Steel expanded metal is produced from one steel plate or roll through simultaneously slitting and stretching, which forms a wide array of diamond shaped openings with uniform sizes. During the expanding process, the metal can be expanded up to ten times its original width, losing up to 80 % its weight per meter, and becomes more rigid. It is lighter, less expensive than a single metal sheet, and also allows for free flow of liquid, heat, air and sound, yet producing impenetrable barrier to larger solid objects (or persons). Compared with the traditional flat metal sheet, steel expanded metal has more notable advantages for its versatile applications. More and more new applications are found for it in the family, office, and other industrial, commercial fields.

How is steel expanded metal made?
Steel expanded metal is manufactured by a process of shearing and stretching under a precisely programmed machine, which produces precise apertures but stretches the metal sheet (See more details in Technology). Different specifications can be made by changing the material or the expanded style.

Two types of expanded metal
Steel expanded metal is manufactured in two ways: raised expanded metal and flattened expanded metal. Raised expanded metal is also known as standard expanded metal, it has diamond openings with slightly raised surface. Flattened expanded metal is manufactured by passing the standard expanded sheet through a cold roll reducing mill, forming diamond openings with flat surface.
