Stainless steel wire mesh is a type of mesh material made from stainless steel wires through processes such as weaving, welding, or perforating. It is characterized by corrosion resistance, high strength, high-temperature tolerance, and ease of cleaning, making it widely applicable in industrial, construction, household, and high-tech fields.
Core Features
Corrosion Resistance
Thanks to the passive film formed by chromium (typically ≥10.5%), it resists erosion from water, acids, alkalis, and various chemical media, making it suitable for humid or corrosive environments (e.g., marine or chemical plants).
01
High Strength and Durability
Stainless steel wires (common grades: 304, 316, 316L) exhibit high tensile strength, and the mesh structure remains stable, resistant to deformation or breakage over long-term use.
02
High/Low Temperature Resistance
Maintains performance in high-temperature (up to 800°C, depending on the grade) or low-temperature environments, suitable for boiler protection, refrigeration equipment, etc.
03
Hygienic and Easy to Clean
Smooth surface minimizes bacterial or dirt adhesion; can be cleaned with high-pressure water jets or steam, meeting sanitary requirements in food processing, medical, and kitchen applications.
04
Permeability and Filtration Function
Precise mesh sizes (from micron to centimeter levels) allow for functions such as light transmission, ventilation, filtration, and screening.
05
Common Manufacturing Processes
| Process Type | Characteristics and Application Scenarios |
| Woven Wire Mesh | Wires interlaced in patterns like plain weave, twill weave, or Dutch weave. Commonly used for screening, filtration, and protective nets. |
| Welded Wire Mesh | Crosspoints welded by resistance welding, offering firm mesh and rigid structure. Suitable for shelving, fencing and construction reinforcement. |
| Perforated Mesh | Holes punched directly into steel sheets, with various shapes (round, square, etc.). Used for decoration, ventilation grilles, and acoustic panels. |
| Crimped Wire Mesh | Wires pre-crimped into wave shapes before weaving, enhancing elasticity and anti-slip properties. Common in mining screens and stair treads. |
Common Materials and Grades
| Grade | Characteristics and Suitable Environments |
| 304 | General-purpose (18% chromium, 8% nickel), resistant to atmospheric corrosion and common chemicals. Suitable for household, food industry, and architectural decoration. |
| 316 | Contains molybdenum (2-3%), offering stronger resistance to chloride corrosion. Ideal for marine environments, chemical equipment, and medical devices. |
| 316L | Low-carbon version with better intergranular corrosion resistance after welding, used for high-temperature welding scenarios. |
| 430 | Ferritic stainless steel (nickel-free), lower corrosion resistance but cost-effective, suitable for dry environments or indoor decoration. |
