QSIF Expanded metal sheet is made by first creating multiple slits in the sheet, and then stretching the sheet while it retains its structural integrity as it does not undergo the stress of having shapes punched in it and the mesh-like pattern. The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. These raised strands can be flattened later in the process if desired. QSIF expanded can be at any thickness and strand dimensions (weight and structural design requirements). Expanded metal features:

·         Mechanical properties and is an excellent conductor.

·         Weight is light enough for outer wall hanging 

·         Anti-corrosive

·         Used as decorative mesh for building outer wall

·         Easily fabricated, finished, installed and formed 


Hot Rolled, Hot Rolled Galvanized, Stainless Steel, Aluminium plate


Regular Expanded Metal is an open mesh, finished product that is simultaneously die-cut and expanded as it moves through progressive dies on a press. In the expanding process, the metal can be expanded up to ten times its original size, lose up to 80% of its original weight per square foot, and still retain form and rigidity. (Regular Expanded Metal can also have referred to as “Raised” or “Standard” Expanded Metal.)


Flattened Expanded Metal is Regular Expanded Metal that has been passed through flattening rolls. This rolling process reduces the thickness of the sheet, stretches the pattern of the sheet, and provides a smooth flat finish, reducing the overall thickness and elongating the diamond pattern.
