Product Description

Expanded metal mesh is manufactured from solid sheets/coils of stainless steel, aluminum, carbon steel or other alloys that can be expanded.
The sheets/coils are fed into the expanding machine, and the precision die cuts and stretches the metal in a single operation. Then the material is sheared and stretched into a particular pattern with uniform opening sizes.
The metal sheet can be expanded up to ten times its original width, and the final product is lighter per meter and stronger per kilogram than its original sheet. No material is lost in the manufacturing process. The expanded metal mesh won't unravel because of its strong material properties. Even if the finished metal sheet is cut at one or more points, the remaining strand intersections can hold the sheet together.

Five steps for the manufacturing process

1. The metal sheet advances between the blades one strand width beyond the lower.
2. The upper blade descends to form one half of the diamond design.
3. The upper blade ascends to its original starting and transverses shift one half of diamond to the side as the metal sheet advances another strand width passing the edge of the lower blade.
4. The upper blade descends again to form another row of half diamonds to complete a full diamond pattern.
5. The upper blade ascends again to its original starting position, and the cycle continues until the sheet of expanded metal is complete.

Raised expanded metal
Also named standard expanded metal. It is a finished product as it comes from the press. The raised configuration adds rigidity and anti-slip resistance to the mesh.
Flattened expanded metal
Flattened expanded metal is manufactured by passing the standard expanded metal through a cold roll reducing mill, providing a flattened surface and reducing thickness.
Short way of design (SWD)
The length of short diamond diagonal from one pitch point center to another pitch point center.

Long way of design (LWD)
The length of long diamond diagonal from one pitch point center to another pitch point center.
Short way of opening (SWO)
The length of short diamond diagonal.

Long way of opening (LWO)
The length of long diamond diagonal.

Strands
The sides of expanded metal design.

Bond
The solid intersection of two strands.

Strand thickness
Thickness of the metal that to be expanded.

Strand width
Metal plate length for making one strand.

LW
Long way of expanded metal sheet.

SW
Short way of expanded metal sheet.

END SHEARING

• • End bond shearing

One end is cut on the bond parallel to the SWD, the other end usually has open diamonds.

• • End random shearing

The shearing direction is parallel to the SWD. The end random cut normally leaves open diamonds at the ends.

SIDE SHEARING

• Side bond shearing

Side bond cut is made along the length of the metal sheet on the center line of the bond over the specific width.

• Side random shearing

Side random shearing is cut that is parallel to the LWD dimension of the metal sheet, leaving opening diamonds.

Give complete style specifications to avoid possible error when ordering expanded metals.

When Ordering Expanded Metals Please State:

1. Quantity of sheets required.
2. Type of material: Aluminum, carbon steel, stainless steel, or galvanized.
3. Thickness or gauge of material.
4. Standard or flattened.
5. Mesh reference.
6. Sheet size (list SW first and then LW). Example: 4' SW × 8' LW.
7. Tolerances (if required).

"Decorative expanded metal offers aesthetic appeal solution in your architectural and decorative demands."
Expanded metal is a versatile product that has countless applications throughout industry. Made from various materials, it is rigid, non-ravel piece
of metal that is slit and stretched in the expanding process, making it greater strength to weight ratio than solid sheet steel.
Expanded metal comes in four basic types: standard expanded metal, flattened expanded metal, decorative expanded metal and expanded metal grating.The versatility of expanded metal makes it ideal for industrial, commercial and domestic applications.
Decorative expanded metal is favored by more and more architectural designers as mechanical requirements in design are not the only things to be concerned, aesthetic appeal of the product takes more predominance.

  Features of decorative expanded metal

• Openings permit free flow of light, heat, sound & air.
• It won't unravel when cut, unlike woven wire mesh.
• Available in a variety of mesh configurations and decorative patterns.
• A wide range of colours and openings.
• Cost effective and environmentally friendly.
• Raised surface is slip resistance and also ideal for walkways.
• Light weight is ideal for outer wall hanging
• Durability and low maintenance.

Specifications
