Super expanded metal(Materials)
Feature
Super expanded metal is a mesh that is formed by cutting metallic foil and expanding it by 1/2 SW.
Super expanded metal is made in a high efficiency process, and its unique structure makes it extremely strong.

Processing Options
1. Hoop processing
・The metal is wound around a paper or iron tube.
・Diameter of the tube is 76m/m
・Max 1000m/R depend on the number of the winds
・Diameter of the tube is 76m/m
・Max 1000m/R depend on the number of the winds
2. Cut processing
3. Expansion process with rib attached
We can produce to your specifications : We can change the ribbed and expanded part as requested.
Using our original technique, we can process metallic as thin as 30 microns.
This processing is possible for both standard and flat types.
It is possible to cut away and then wind the metal.
Secondaty Processing
1.Press processing >>> Stamp to your desired form.
2. Bend processing >>> Bend to your desired form by using a bending machine.
3. Cut processing >>> Cut to desired size.
4. Slit processing >>> Slit to desired width and length.
5. Spot welding >>> Spot weld to the desired form.
Basic Equations
Expansion rate
Ratio of expansion (expanded from material of 1m）
Expansion rate=SW/2／W
Expansion rate=SW/2／W
Unit weight of expanded metal
Weight for the expanded metallic foil
Unit weight of the expanded metal=weight of the metallic foil per 1m/expansion rate
Unit weight of the expanded metal=weight of the metallic foil per 1m/expansion rate
Aperture rate
Space rate of the metallic foil and expanded metal
Aperture rate=1-(unit weight of expanded metal/unit weight of metallic foil)
Aperture rate=1-(unit weight of expanded metal/unit weight of metallic foil)
