Manufacturing process:
Expanded metal is plate or sheet cut and stretched into a mesh. Also known as extruded or stretched metal.
The pattern of the mesh can either be staggered or in a straight pattern with all rows and columns aligned. Extruded / expanded mesh has varied opening rate designed to meet the applications. Opening size and pattern of the expanded metal determines the passage of air, liquid or light.
Different sheet thickness and materials of metal can be chosen. L.W.D (Long Way Diamond) and S.W.D. (Short Way Diamond) are commonly used to indicate the desired length and width of the diamond shaped mesh holes.
Manufacturing process: Stretching metal sheets into diamond hole expanded meshes
Specification term for standard expanded mesh and flattened mesh:
Expanded Metal, Standard Flattened Diamond Mesh, Specifications:

Standard Expanded Sheet, comes in a variety of gauge and opening sizes.
The strands and bonds are set at a uniform angle. This design provides a rigid, raised, slip-resistant surface, suitable for treads, catwalks, guarding sheet with good air flow.
Flattened Expanded Metal
Flattened expanded metal is produced by metal sheet stretching then flattening. Normally into diamond shape hole. Materials covering ss, steel, alu and alloys. This product is suitable for ceiling panels, facade mesh, sun shade and partitions.
Hexagonal Hole Stretched Metal
The hexagonal mesh gives the metal sheet extra strength while allowing the passage of air, light, heat, sound and liquid. Hexagonal openings are mostly used for heavy expanded sheet. This product is suitable for grating, vent panels, fencing uses.
Raised metal sheet designed for facade, security and privacy screen, ventilation screen, functional and decorative mesh.
Micro hole metal mesh
Small opening metal mesh in light gauge metal. Mostly used in filters.
Expanded alu or ss mesh ceilings for modern architectures, for vent and light diffusion
Ceiling panels: 16x30mm and 22x55mm diamond hole

Expanded metal ceiling panel has several advantages:
Excellent air flow
Wear-resistance
Strong tensile strength with less heavier
Easy to install and low cost
Major metal materials are stainless steel, steel and aluminum. Finishes can be plain metal or powder coated. Using of expanded metal mesh cladding can not only add aesthetic touch to the building, it can also protect the architectural structure from the harsh glare of the sun.
Aluminum expanded sheet for ceiling and external wall cladding:
Expanded aluminum is a fashionable decoration elements in buildings construction. It is widely used in making of air filtration system, machine guards, safety door & window screening, room dividers, decorative ceilings, grating and partition curtains.
Stainless Steel Expanded Sheet for Wall Cladding
The stretching knuckles support weight and withstand stress better than joints of welds.
Higher strength-to-weight ratio than the original sheet material.
Allows free passage to light, heat, sound and air.
Screening effect.
Makes an excellent reinforcement material.

Surface treatments:
1) For aluminum material:
- Without treatment, plain aluminum
- Anodized finish (Colours can be silver, blue, green, yellow, pink, red, black, other colors)
- Powder coated
- PVDF (surface will be much more smooth, level off and glossy, it also has a much longer life span than common treatment)
2) For steel material:
- Galvanized : Electric galvanized, Hot-dipped galvanized
- Powder coated
- Spray painted
Application:
