What is perforated stainless steel mesh?

Perforated Stainless Steel Mesh, also known as stainless perforated sheet or stainless steel perforated metal, is a perforated metal sheet with regular holes punched out on metal sheets (except 304, 316, 430 stainless steel, aluminum, galvanized steel, aluminum-zinc coated steel, etc.) through precision stamping technology. The hole shapes include round, square, diamond, slotted, etc., which have the functionality and decorativeness of filtering, air permeability and light transmission while maintaining the complete structure. Its hole shape, hole spacing, plate thickness and roll width can be customized, and it is used in the fields of filtration, screening, and noise reduction, with outstanding corrosion resistance.

Surface treatment

• 2B: The surface is matte silver-white, flat and smooth. It is the most commonly used basic surface obtained by annealing and pickling after cold rolling, suitable for further processing.
• BA: Bright annealing after cold rolling, the surface is as bright as a mirror but slightly inferior to the mirror, with high reflectivity, often used for decoration or scenes requiring high cleanliness.
• NO.1: The surface after heat treatment and pickling after hot rolling is dark silver-white, rough with traces of oxide scale, high strength, and mostly used in industrial load-bearing structures.
• NO.4: The surface is ground to form continuous fine stripes, with a hair-like matte, wear-resistant and easy to clean, commonly used in kitchen equipment and medical equipment.
• HL: The surface has continuous straight stripes (commonly known as “brushed”), the texture is coarser than NO.4, with both decorative and wear-resistant, widely used in home appliances and decoration fields.
• 6K: The mirror effect is inferior to 8K, the surface is bright but slightly contains fine textures, the reflectivity is moderate, the cost-effectiveness is high, and it is suitable for decoration scenes with slightly lower requirements for mirrors.
• 8K: After multiple grinding and polishing to a mirror effect, the surface is as bright as a mirror and has a very high reflectivity. It is mainly used for high-end decoration, mirror furniture, etc.

Different Hole Shapes

Benefits of perforated stainless steel mesh

• Strong corrosion resistance: The dense oxide film formed by chromium elements can effectively resist the corrosion of chemical substances such as acid, alkali, and salt. 304 can withstand oxalic acid, sulfuric acid, and nitric acid, and 316 performs better in chloride ion environment.

• High strength and durability: It has high tensile strength, strong deformation resistance, wear resistance of 3-5 times that of ordinary sieve plates, and a service life of up to decades. The maintenance frequency is low, the replacement cycle is long, and the total cost is lower than that of ordinary materials.
• Easy to process: It can punch out round holes, square holes, diamond holes, special-shaped holes, and other hole types, and can be processed into flat plates, arcs, and rolls. The aperture, hole spacing, and plate thickness can be adjusted as needed, and full-size customization is supported.
• Beautiful and practical: The surface is smooth and can be mirror-polished. The punching design can form geometric patterns and brand LOGOs. The hollow design reduces weight while maintaining structural strength. Through the optimization of aperture and arrangement, the dual effects of noise reduction and ventilation are achieved.

• High safety: high density, stable structure, able to withstand external impacts such as vehicle collision and equipment vibration, melting point of about 1400℃, non-flammable, non-toxic, and will not release harmful gases in a fire.
• Easy maintenance: dust is not easy to accumulate on the surface, stains are resistant, and cleaning is convenient. The material can be recycled and reused. Lightweight design reduces transportation and installation costs. Aluminum plate perforated mesh combines the corrosion resistance of stainless steel with the lightweight of aluminum to further reduce costs.

 

Benefits of Perforated Plate Sieves

Compared with wire mesh sieve, perforated plate screen is more durable. It is made of a whole piece of metal plate, with a solid structure, strong impact resistance and tensile resistance, and can withstand high pressure and hard material impact, suitable for processing large particles and high hardness materials. The wire mesh sieve is woven with fine wires, and the nodes are easily damaged. When high-intensity operation or processing hard materials, it is easy to break, and the mesh is deformed, and the durability is relatively weak.

Applications

304 vs. 316 Stainless Steel Perforated Sheet Mesh

Material properties

Features	304 stainless steel	316 stainless steel
Composition	18% chromium, 8% nickel	16% chromium, 10% nickel, 2% molybdenum
Corrosion resistance	Resistant to general acid and alkali, a humid environment	Stronger, resistant to seawater and chloride ion corrosion
Cost	Low	Higher (molybdenum content)
Applicable environment	Indoor, general industry	Coastal, chemical, high saline, and alkaline environments

Performance Differences

• 316 perforated SS sheet: Molybdenum significantly improves the ability to resist pitting corrosion, suitable for harsh environments such as ships, coastal buildings, medical, and food industries.
• 304 perforated SS sheet: High cost performance, widely used in interior decoration, screens, and mechanical equipment protection.

Service life 

The service life of stainless steel perforated plates is related to the material, environment and maintenance. In dry indoor places, the service life of 304 stainless steel perforated plates is 20-30 years, while 316 stainless steel is longer; in coastal areas and chemical areas, 316 stainless steel perforated plates are recommended, with a service life of 10-20 years; and in wear scenarios, such as screening equipment, its service life is 8-15 years.

Perforated Stainless Sheet Mesh vs. Perforated Aluminum Sheet Mesh

• Stainless steel metal mesh is known for its high strength, durability, and corrosion resistance. It is also heat and fire resistant, making it ideal for high temperature applications. Stainless steel is often preferred over aluminum in applications where high strength and durability are required.
• Perforated aluminum metal mesh is a lightweight, strong, and durable material, although not as strong as stainless steel. Aluminum is commonly used in marine and outdoor applications and has a strong corrosion resistance. It is a more popular choice than stainless steel for projects where weight and cost are important considerations.

How is Perforated stainless steel mesh made?

• Material selection: 304 stainless steel is selected for general industrial and civil scenes, and 316 stainless steel is selected for chemical coastal scenes.
• Plate thickness: Select thickness according to purpose, 0.8mm-2mm for architectural decorative net, 3mm-6mm for mechanical protective net.
• Mold design: High-precision CNC mold processing equipment is used to achieve aperture error ≤±0.1mm, hole spacing error ≤±0.15mm, and support more than 20 hole types such as round holes, square holes, and diamond holes.
• CNC stamping: Using CNC punching machine, stepper motor feeding, and PLC control system to achieve accurate stamping of plates, and gradient hole design can be performed.

• Surface treatment: There may be tiny scratches on the surface of the plate after stamping, and the appearance is improved by polishing or wire drawing.
• Cutting and trimming: According to the needs, the whole roll of plate is cut into specified sizes, and the excess edge material is removed by laser cutting or shearing machine.
• Leveling: Use a leveling machine to level the deformed plate after stamping to restore the original flatness.
• Cleaning: Remove lubricant residues through the degreasing process to ensure that the surface cleanliness meets food grade or medical grade standards.
• Powder coating: Optional, using epoxy resin or polyester powder, customizable color and enhanced weather resistance.
• Quality control: Real-time monitoring of hole diameter and hole spacing, dimensional tolerance, salt spray test, tensile test, board width, board length, board thickness and other tests through laser sensors.
• Packaging and transportation: Wrapped with moisture-proof paper + fixed with wooden pallets to ensure no deformation during long-distance transportation, the maximum weight of a single roll can reach 2 tons.
