Wire mesh is usedLow carbon steel wire, medium carbon steel wire,High carbon steel wire，Stainless steel wireThe general term for materials woven or welded into a mesh.Production processThere are: ordinary braided type, embossed braided type and spot welded type.It is mainly made of steel wire and processed into mesh by professional equipment, so it is called steel wire mesh.
national standardThere are certain requirements for the specification of steel wire mesh. The diameter should match the mesh size, not just the diameterPlastering layerThe grid should not be larger than 20 × 20, and the diameter should not be less than 1mm. It is not meaningful to choose the diameter alone. It is better to choose 0.9 × 40 × 40 or 0.6 × 10 × 10 steel wire mesh. I'm afraid it is 0.6 × 10 × 10.The role of steel wire mesh in external wall plastering is mainly a measure to prevent falling off from the perspective of safety, and its role in anti cracking is relatively small due to the problem of location;For the external insulation systemface brickAs for the finish, its function should be first anti falling and then anti cracking. In this case, the grid of 0.6 × 10 × 10 should be selected. These are some empirical choices. The conversion of the grid comes from the specification of the steel mesh specified by the state, and the grade conversion of the steel content should be used.
The indexes of wire mesh include mesh size, wire diameter, steel content per square meter, zinc content, etc., mainly considering the corrosion resistance of wire mesh and the safety of the system!
Galvanizing ratio of steel wire meshFilament diameterMore importantly, the amount of galvanizing is very importantHot plating, welding before plating is better than plating firstPostweldGood. As for wire diameter, it is better to consider the on-site construction and meet the safety needs, 0.6~0.7.

English name: steel wire mesh
hardware cloth
Steel wire mesh is a necessary building material for building crack prevention and wall insulation.
CommonMetal meshThere are two types:Steel net(dragnet) and wire mesh (woven mesh)
Steel netIt is made of 1.2mm thick steel plate by punching and stretching.Strong, durable, and can be directly plastered by nailing steel mesh independently.
Wire mesh is made of fine steel wire orGalvanized iron wireweaveNetworking, with different mesh density and size, and the unit is "mesh".Must be set off behind（Cement board, wall, etc.).
It is used for decoration with steel plate mesh and steel wire mesh,Plastering net，cement mortarThe mortar extruded from the back of the mesh shall be fixed after setting, and the cement mortar shall be fully wrapped to protect the metal mesh from corrosion, similarreinforced concreteProtection principle of.Among them, steel mesh is brushed before useanticorrosive paintOf.
The material of wire mesh is further expanded, mainly including: long specificationStainless steel wire mesh(low nickel, 302304316316L, etc.), mainly used for filtration in chemical enterprises;manganese steelSteel wire mesh (65 manganese, 75 manganese, etc.), mainly used for cement screen, withOxidizabilityScreening;45 # steel wire mesh, mainly ordinary mesh.Hot dip galvanized steel wire mesh, mainly used for external insulation of building exterior wall
Advantages of hot-dip galvanized steel wire mesh: excellent corrosion resistance and durability
External wall insulation netThe varieties include hot-dip galvanized steel wire mesh, alkali resistant glass fiber mesh cloth, etc.
Purpose and effect:The external wall insulation net is mainly used for the external wallcast-in-place concrete、High-rise residentialAnd plays an important structural role in the thermal insulation systemHot dip galvanized steel wireGridPolystyrene boardPlaced inside and outside the external formwork of the external wall to be pouredInsulation boardIt can survive with the wall at the same time. After the formwork is removed, the insulation board and the wall are combined into one, thus saving manpower, time and installation costs.Hot dip galvanized steel wire meshPolyphenylThe plate is large, light and easy to construct. The exterior decoration surface can be used for facing bricks, which is simple to operate. It can also be constructed in winter.
The industry standard Steel Wire for Machine Knitted Wire Mesh has been approved by the expert group in Hangzhou.Experts from the National Committee of Steel Standardization Technicians believe that the standard is based on the actual production of steel wire for machine woven wire mesh in China, and the indicators are set reasonably, which reflects the scientificityprogressivenessAnd operability principle, which has reached the international advanced level and has broad application prospects.
The Development and Reform Office of the National Development and Reform Commission (NDRC) listed the Steel Wire for Machine Knitted Wire Mesh in the formulation plan of the national ferrous metallurgical industry standard for 2008-2009.

Benefits of using wire mesh
1、 It can effectively fix pipes and has extremely high heat conductivity
The product is made of high-quality low-carbon steel wire, which is formed by automatic precision and accurate mechanical equipment spot welding, and then is galvanizedsurface treatmentConventional British standard production, the mesh surface is smooth and tidy, the structure is firm and uniform, and the overall performance is good. Even if it is partially cut off or under pressure, it will not be loose. It is the most corrosion-resistant mesh in the whole wire mesh, and it is also one of the most widely used meshes. High quality corrosion resistance makes it popular in the breeding industry. The smooth and tidy mesh surface increases the appearance,It can play a decorative role, which also makes itMining industryDue to the use of low carbon and high-quality materials as raw materials, it is unique. The ordinary iron screen is not flexibletoughnessIt determines its plasticity in the use process, so that it can be used in the deep processing and manufacturing of hardware technology, the batching of complex walls, underground leak proof and crack proof, and the lightweight mesh body, which makes the cost much lower than the cost of the screen, and can realize its economy and benefits.
