Steel mesh is a type of metal screen mesh widely used in various industries. The following provides a detailed introduction from multiple aspects:
1, Basic Definition and Production
Definition: Also known as metal plate mesh, diamond mesh, metal expansion mesh, etc., it is a mesh like tensile object formed by special processes such as punching, shearing, and stretching of metal plates (such as low-carbon steel plates, stainless steel plates, aluminum plates, copper plates, etc.).
Production process: The metal sheet is first punched and cut into gaps using equipment such as steel mesh punching and cutting machines, and then stretched to expand the gaps into mesh holes. The shape and size of the mesh holes can be designed according to needs, such as common diamond holes, as well as hexagonal, circular, and irregular hole holes.
2, Classification method
By material:
Carbon steel mesh: Low cost, high strength, easy to rust, requiring anti-corrosion treatment, commonly used in industrial and construction scenes with low anti-corrosion requirements, such as building batch cement and ordinary mechanical equipment protection.
Stainless steel mesh: corrosion-resistant, anti-oxidation, suitable for harsh environments such as humidity, acidity, and alkalinity, such as food processing, chemical, and marine engineering fields, used for equipment protection, filtration, etc.
Aluminum mesh: lightweight, rust free, aesthetically pleasing in color, and has a certain degree of insulation properties. It is commonly used in building decoration (such as curtain walls and ceilings), handicraft manufacturing, electronic equipment protection, etc. After anodizing treatment, its performance is better, and the insulation layer can resist breakdown voltage.
According to hole shape:
Diamond shaped steel mesh: the most common, with diamond shaped mesh holes, it combines beauty and strength, and is widely used in building decoration, protective fences, and other applications.
Hexagonal steel mesh: The holes are hexagonal and the structure is relatively more stable. It is used in some scenarios with high requirements for load-bearing and protection, such as heavy machinery protection and mine support.
Round hole steel mesh: The holes are circular, which provides more uniform force distribution. It is commonly used in the fields of filtration and screening, such as as as filter mesh and ore screening mesh.
Irregular steel mesh: designed with hole shapes according to special requirements, used for personalized scenarios such as handicrafts and special equipment matching.
By aperture:
Micro porous steel mesh: with a long pitch of ≤ 10mm and fine mesh holes, used for precision filtration, dust prevention of electronic devices, such as audio mesh covers and electronic component protective nets.
Small hole steel mesh: with a long pitch of 10-25mm, it is used in building decoration (such as small handicrafts) and lightweight protection.
Medium hole steel mesh: with a long pitch of 25-50mm, commonly used for building plastering and ordinary guardrails, such as plastering reinforcement for building exterior walls.
Large hole steel mesh: with a long pitch of 50-100mm, it is used for the protection of large mechanical equipment, highway guardrails, sports field enclosures, etc. It is convenient for ventilation and has a certain degree of protection.
By thickness:
Lightweight steel mesh: thickness ≤ 1.5mm, lightweight, easy to process, commonly used in building decoration (such as ceilings, partitions) and handicraft manufacturing.
Medium sized steel mesh: thickness 1.5-3.0mm, moderate strength, suitable for highway guardrails, mechanical equipment protection and other scenarios.
Heavy duty steel mesh: with a thickness of ≥ 3.0mm, high strength and load-bearing capacity, used for oil tank truck foot nets, heavy machinery work platforms, mine escalators, etc., to ensure the safety of personnel and equipment.
According to anti-corrosion processing:
Spray painted steel mesh: The surface is sprayed with paint to form a protective layer, with a variety of colors that can balance anti-corrosion and decoration. It is commonly used in building decoration and outdoor fences, but the paint is prone to wear and requires regular maintenance.
Immersion steel mesh: The mesh body is immersed in plastic powder solution and cured at high temperature to form a plastic coating, which is corrosion-resistant, wear-resistant, and has long-lasting color. It is widely used in highway guardrails, residential fences, and other applications.
Galvanized steel mesh: divided into hot-dip galvanizing and electroplating galvanizing. Hot dip galvanizing has strong corrosion resistance and long service life, and is commonly used in outdoor engineering such as highway guardrails and mine support; Electrogalvanizing has low cost, slightly weaker corrosion resistance, and is suitable for mild indoor protection scenarios.
3, Performance characteristics
Structure and strength: The mesh holes are uniform and the mesh surface is flat. Through punching, shearing, and stretching processes, the metal stems (edges of the mesh holes) are connected to each other, resulting in high overall strength and the ability to withstand certain pressure and tension without deformation. Heavy steel mesh can be used as a work platform, escalator, and to carry the weight of personnel and equipment.
Ventilation and Light Transmission: The mesh structure allows air and light to pass through, and in building decoration (such as curtain walls and ceilings), it can regulate the indoor light and heat environment; When used as a protective net, it does not affect visibility and ventilation, such as highway guardrails and sports fences, which provide both protection and visibility.
Aesthetics and plasticity: The unique mesh shape (diamond, hexagonal, etc.) is decorative, and different materials and surface treatments (such as aluminum mesh anodized for beautiful color) can be adapted to a variety of styles; And it has a certain degree of flexibility, can be bent and cut, and can adapt to complex shape installation requirements, such as for the decoration of curved building exterior walls.
Environmental protection and economy: Metal materials can be recycled and reused, and the production process is relatively environmentally friendly (mainly cold processing, with less dust and noise); Compared to solid boards, "hollowing out" redundant materials reduces weight, saves raw materials, has low transportation and installation costs, and offers high cost-effectiveness.
4, Application Fields
Construction industry:
Decoration engineering: used for building exterior wall curtain walls, indoor ceilings, partitions, stair railings, etc., such as aluminum mesh curtain walls, which are beautiful, ventilated and transparent; Diamond shaped steel mesh ceiling, fashionable and industrial style.
Structural reinforcement: In civil engineering and construction, steel mesh (such as light and medium) is used instead of traditional steel mesh when batch cement, which has high tensile strength, overall firmness, crack resistance, and earthquake resistance. It is commonly used in high-rise buildings and factory buildings.
Protective facilities: Construct walls around the construction site to isolate the construction area; Install steel mesh guardrails on balconies and stairs of buildings to ensure personnel safety.
Transportation sector:
Highway and railway: Steel mesh (mostly medium-sized and large holes) is used for highway guardrails and protective nets on both sides of the railway to prevent pedestrians and animals from entering and avoid traffic accidents; Bridges and tunnels also use it as protective barriers.
Transportation facilities: heavy-duty steel mesh for the foot pedal of oil tank trucks, anti slip and load-bearing; Ship platforms use steel mesh to prevent slipping and ensure the safety of personnel walking.
Industrial production:
Equipment protection: Steel mesh isolation and protection are used in factory workshops and warehouses to divide functional areas; Transformers, distribution cabinets and other equipment are used as protective enclosures to prevent electric shock and collision.
Filtering and screening: As a filter mesh or ore screening mesh (with circular holes, irregular holes, etc.), it is used in food processing, chemical industry, and mining to filter impurities and screen materials.
Work platform: Heavy steel mesh is used for work platforms, escalators, and walkways of heavy machinery, boilers, oil mines, locomotives, 10000 ton ships, etc. It has high strength, anti slip properties, and ensures safe operation.
Agriculture and Landscape Architecture:
Agricultural facilities: Build steel mesh fences and support structures for greenhouses, and use them to isolate and protect breeding pens, which are durable and ventilated.
Landscape: Steel mesh (impregnated and painted) is used for the perimeter walls and garden fences of the residential area, providing both protection and aesthetic appeal; Fencing around parks, scenic spots, and sports venues to define areas and ensure safety.
Other fields:
Craft manufacturing: producing high-end speaker mesh covers (micro porous, beautiful), decorative ornaments, etc., using unique mesh holes and metal texture.
Electronic appliances: Dust proof nets and heat dissipation nets are installed inside electronic devices, such as speakers and computer cases. Micro porous steel mesh can filter dust without affecting heat dissipation.
5, Theoretical weight and specification parameters
Theoretical weight calculation: The formula is "steel mesh weight=mesh length ÷ (short pitch ÷ 2) × stem thickness × mesh width × plate thickness × 7850" (the unit needs to be converted to meters uniformly). Through this formula, the weight of steel mesh of different specifications can be estimated, which is convenient for procurement and transportation accounting.
Common specification range:
Thickness: 0.2-8.0mm, covering light, medium, and heavy-duty application scenarios.
Aperture (long pitch x short pitch): National standards include 2 × 4mm, 3 × 6mm,..., 50 × 100mm, etc; Non standard can also be customized with special specifications such as 2.5 × 4mm, 4 × 6mm, etc; Special steel mesh has more flexible aperture, such as 18 × 20mm, 22 × 50.8mm, etc., to meet diverse needs.
Mesh size: 600-4000mm in length, 600-2000mm in width, and can also be customized to larger or special sizes according to project requirements.
6, Installation and maintenance
Installation method: Depending on the application scenario, welding (such as industrial equipment protection, heavy-duty platforms), bolt fixation (such as building curtain walls, guardrails), binding (such as building batch cement reinforcement), and other methods can be used. During installation, it is necessary to ensure that the mesh body is flat and firmly connected to avoid looseness and deformation.
Maintenance points:
Cleaning: Regularly clean the surface dust and dirt, which can be washed with a soft brush or clean water to maintain aesthetics and ventilation. For example, steel mesh used for building decoration, dirt can affect the visual effect.
Inspection and repair: Check if the connections are loose and if the mesh is damaged. If any problems are found, repair or replace them in a timely manner. If the protective mesh is loose, it may lose its protective function and needs to be re fixed; The damaged area can be cut and welded (metal material).
Anti corrosion maintenance: For steel mesh treated with anti-corrosion methods such as painting, dipping, and galvanizing, if the coating is damaged, it should be repaired in a timely manner to prevent rusting and extend its service life. For example, if the galvanized layer is worn, it can be repainted with galvanized paint.
