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.
One piece of steel expanded metal mesh with uniform diamond openings.
SEM-01: Steel expanded metal is manufactured into sheet profile, its flattened surface is rolled from raised expanded metal.There are three small coils of expanded metal mesh, and they have different mesh sizes.
SEM-02: We offer steel expanded metal in coils, and the sizes can be made to order.
There are many rolls of steel expanded metal that are painted red.
SEM-03: Steel expanded metal is often painted red for anti-rust.One part of steel expanded metal, and they are galvanized.
SEM-04: Hot-dipped galvanized surface treatment is commonly used in steel expanded metal for corrosion resistance.
The picture shows eight pieces of expanded metal, which has different opening sizes.
SEM-05: Diamond openings of expanded metal vary in size and shape for different uses.There are six round expanded metal slices, they have different sizes.
SEM-06: Steel expanded metal is cut into round shape for specific use, and although cut at the end, the remaining part won't ravel and keeps its structure.
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.
