Expanded Metal


Expanded metal is manufactured through cutting and expanding a solid sheet of metal in special machines. The mesh is formed from a single piece of metal; no welding or weaving is involved.
No joints - electrically and mechanically stable
No welded knots - less risk for ruptures
No woven threads - does not unravel

Expanded metal can e.g. direct, clean or break the flow of air. It can also reinforce, insulate, or protect buildings. It is an efficient conductor of electricity and heat and does not fray or unravel when cut into irregular shapes.

If the expanded metal is flattened it regains the original thickness (strand thickness) of the sheet metal. The flat surface that emerges from this procedure can be used for different optical effects or simply to save space. The flattened expanded metal has, however, a somewhat lower carrying capacity and is less slip-resistant.

Materials: stainless steel wire, iron plate, copper plate, aluminum plate

Uses: widely used in the core of filter, medicine, filtering, breed, battery, mechanical protecting, making the crafts, the meshes for the high-grade sound box, decorate, the seating for children, small basket and basket

The Expanded metal is defined by the long way of mesh (LWM) and short way of mesh (SWM), followed by width of strand and sheet (strand) thickness.

Terminology

SWD: Short way of diamond
LWD: Long way of diamond
THICKNES: Thickness of Sheets
STRAND:Strands from the sides of the expanded metal openings.
LWM: The distance of LWD direction
SWM: The distance of SWD direction

One of the significant advantages of expanded metal is the fact that it provides for large open areas and is lightweight. Most of the above mentioned mesh combinations have these characteristics. Since the actual weight of the expanded metal is comparatively low, and the carrying capacity is high, the (strand) thickness of the original sheet can usually be thinner than expected. The strand width can be varied - if you wish for a grid-like look you should select a strand width close to the strand thickness; if you wish for a heavy look, a larger strand width must be selected.

The width of the expanded metal (parallel to the long way of mesh) is limited by the expanded metal machine of the chosen mesh. The length of the metal is, on the contrary, not limited up to 1,5 mm material thickness. We produce all expanded metal cut-to-size according to your wishes and needs. We can also cut it to form or deliver in rolls, should you require it.
