Product Description
Expanded steel mesh is a metal screen, also known as expanded metal mesh, diamond mesh, iron mesh, expanded metal mesh, heavy steel mesh, foot mesh, aluminum mesh, stainless steel mesh, granary mesh, antenna mesh, filter mesh, and audio mesh wait.
Material: low carbon steel plate, stainless steel plate, aluminum plate, copper plate, nickel plate, magnesium plate, aluminum-magnesium alloy plate and other metal plates.
Surface treatment: PVC dipping (plastic spraying, plastic coating), hot-dip galvanizing, electro-galvanizing, anodizing (aluminum plate), anti-rust paint spraying, etc.
Classified by material: low carbon steel sheets, aluminum plates, stainless steel plates, aluminum-magnesium alloy plates, steel plates, and other plates.
Classified by use: widely used in highways, railways, civil buildings, water conservancy and other construction, various machinery, electrical appliances, window protection and aquaculture, etc. Products with various special specifications can be processed and customized according to customer requirements.
Classified by hole type
1. Fish scale hole steel aluminum metal mesh
2. Hexagonal hole steel and aluminum metal mesh
3. Fancy steel and aluminum metal mesh
4. Turtle-shaped steel and aluminum expanded metal mesh
EXPANDED METAL CHARACTERISTICS
There are two types of expanded metal.
Raised mesh is unchanged from the expanding process where the individual strands are set at an angle to the plane of the sheet which results in a superior strength-to-weight ratio, enhanced sheet rigidity, good anti-slip properties, and an increase in overall thickness of the original raw material sheet due to the angled strands.
Raised mesh is measured from the center of one mesh to the center of the adjacent mesh, this is referred to as the LW and SW Pitch as shown below.
Walkway mesh is described in the same manner as raised mesh.
Flattened mesh is simply a raised mesh that is passed through heavy-duty pressurized metal rolls to create a mesh with a flat surface to the sheet. Flattened mesh is generally processed to the same thickness as the original raw material or just below that base thickness. Flattened mesh is desirable where a lower overall thickness is desirable or if a flat surface is required to have greater surface area for example, when welding into a frame.
Flattened mesh is measured from the internal opening of the diamond, this is referred to as the LW and SW Aperture as shown below.
SHEET SIZE AND MESH ORIENTATION
Expanded metal is available in a wide variety of sheet sizes. The items shown on our website are a guide to the standard items we manufacture as standard stock items.
The sheet size is described as LWD and SWD (LW and SW Dimension). The standard sheet sizes are 2440mm LWD x 1220mm SWD and 1250mm LWD x 2500mm SWD as illustrated here.
Stock sheets are manufactured to a nominal plus tolerance and are likely to be delivered slightly oversized. If exact sizes are required we recommend this be discussed at the time of order.
It is possible to produce other sizes, please contact us for more details.
CUSTOM-MADE PRODUCTS & CUT TO-SIZE ITEMS
We offer a custom manufacturing service where bespoke specifications and sheet sizes can be made to suit your individual needs. This may be a variation to the mesh specification to enhance its performance or to ship the material to you in cut-to-size panels or large format sheets.
All our meshes are capable of being supplied in a cut-to-size finish, the majority being cut in-house on our guillotines. 6mm thick walkway mesh (12-99WR) and certain designer meshes cannot be cut on a conventional metal guillotine so would require cutting by a sub-contract water jet cutting service. Please ask for more details.
The benefit of sheared panels is not only dimensional accuracy and close tolerances but the shearing process ensures sheet squareness.
Expanded Metal which is machine run is not guaranteed to be perfectly square. The only way of creating sheets that are reliably square is to cut them after expanding. The illustration below shows how 'stock' mesh can be out of square, cutting to size is a reliable and quick way of overcoming this.
It is possible to introduce production controls for certain products at the planning stage to overcome the issue of squareness. Certain designer products can be machine-run with very tight squareness and dimensional tolerances so please talk to us to discuss the specific needs of your project.
