Expanded metal sheet
is made by first creating multiple slits in the sheet, and then stretching the sheet. 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. As you can see this process creates no waste (thus keeping down production costs) and it can add structural strength to the product.Expanded metal sheet Characteristics:
One of the benefits from the manufacturing of expanded metal is that the sheet retains its structural integrity because it has not undergone the stress of having shapes punched in it (like perforated sheet), and the mesh-like pattern will not unravel (like woven mesh can do). Expanded metal has been stretched rather than punched, reducing scrap metal waste; making it cost-effective. The main considerations when using expanded metal will be the chosen thickness and strand dimensions (weight and structural design requirements). Expanded metal can be almost transparent (depending on the opening); it has mechanical properties and is an excellent conductor.AVAILABLE THICKNESS AND SIZE?
Common thickness of aluminum panel in stock are 1.0mm,1.5mm, 2.0mm, 2.5mm, 3.0mm and 4.0mm. 1.0mm, 1.5mm and 2.0mm are normally for indoor decoration (partition, screen, ceiling, trim, wall cladding, art and etc.),
2.5-4.0mm are for outdoor usage( cladding wall, balcony guardrails, shaped shutter, fence, gate and etc.).
Regular sizes of aluminum panel materials, standard size is 1220x2440mm, width range is 900~1500mm,
length range is 1800~4000mm, It is flexible enough to be made any shapes according to the shop-drawing.
