Expanded metal specifications
Expanded metal has various specifications, which are mainly classified according to factors such as its aperture, thickness, material and processing method.
Aperture: The aperture size of expanded metal directly affects its air permeability and load-bearing capacity. Common aperture specifications include 2x4mm, 3x6mm, 4x8mm, 5x10mm, etc., up to larger 50x100mm or even larger. According to the aperture size, expanded metal can be divided into four categories: micropore, small pore, medium pore and large pore.
Thickness: The thickness of expanded metal determines its strength and durability. The thickness range is usually between 0.2mm and 8.0mm, and it can be divided into light, medium and heavy expanded metal according to thickness.
Material: The main materials of steel mesh include carbon steel, stainless steel and aluminum. Different materials have different corrosion resistance and strength, suitable for different application scenarios.
Processing method: Steel mesh can be processed by shearing, stretching, stamping and other processes to form a variety of hole shapes such as diamond, hexagon, circle, special shape, etc.
Common terms
In the field of steel mesh, there are some common terms to understand:
Long pitch (LWD): The length of the long diamond diagonal from the center of the node to the center of the node.
Short pitch (SWD): The length of the short diamond diagonal from the center of the node to the center of the node.
Strand: The side of the diamond hole of the steel mesh, the width of the strand is the length of the metal plate used to make a wire stem.
Node (Bond): The connection between two wire stems.
Roll: The steel mesh wound into a roll with a specific length and width.
Wide range of uses
The diversity and flexibility of steel mesh make it widely used in many fields:
Construction field: Steel mesh is often used on scaffolding tables to facilitate the movement and placement of objects by construction workers. At the same time, the steel plate mesh for ceilings has become the first choice for suspended ceilings in high-end places such as hotels, conference halls, and hotels because of its beautiful appearance, durability, and good ventilation.
Transportation facilities: In transportation facilities such as highways and railways, steel plate mesh is often used for guardrail nets, sound barriers, etc. to improve road safety and reduce noise pollution.
Mechanical equipment protection: Steel plate mesh is often used as a protective cover for mechanical equipment due to its high strength and good air permeability, such as tanker foot nets, heavy machinery and boilers and other working platforms, escalators, walkways, etc.
Agriculture and horticulture: In the agricultural field, steel plate mesh can be used as the skeleton and covering material of greenhouses to provide a good environment for the growth of crops. At the same time, it can also be used for fencing and decoration in gardening.
Other applications: Steel plate mesh is also widely used in the manufacture of handicrafts, high-end speaker nets, sports venue fences, road green belt protection nets and other fields. In addition, with the development of science and technology, steel plate mesh has also begun to be used in the production of paper filter products.
