304 Stainless Steel Perforated Mesh Sheet Product Information
1. Basic Parameters
Our 304 stainless steel perforated mesh board is available in a
wide range of specifications. The standard board sizes vary from
small pieces suitable for detailed applications, starting at
300mm×300mm, to large - scale boards up to 2500mm×6000mm, meeting
diverse project demands. The thickness of the board ranges from
0.5mm to 5mm, providing options for different load - bearing and
durability requirements. As for the holes, a vast array of shapes
can be produced, including round, square, rectangular, triangular,
hexagonal, and custom - designed shapes. Hole diameters for round
holes typically range from 0.5mm to 100mm, while side lengths for
square and rectangular holes can be customized according to
specific needs. The hole pitch (distance between holes) can also be
precisely adjusted, with common ranges from 1mm to 100mm, enabling
control over the open area percentage of the mesh board, which
usually ranges from 10% to 70%.
2. Material Characteristics
Constructed from high - grade 304 stainless steel, which conforms
to international standards such as ASTM A240/A240M - 22 and EN
10088 - 2. This material is an austenitic stainless steel alloy,
containing approximately 18% chromium and 8% nickel. The high
chromium content forms a passive oxide film on the surface, which
provides exceptional corrosion resistance, protecting the board
from rusting in various environments, including those with
moisture, mild chemicals, and atmospheric pollutants. The nickel
addition enhances the material's ductility, toughness, and
resistance to stress corrosion cracking, ensuring the board
maintains its structural integrity under different conditions.
3. Manufacturing Process
The production of our 304 stainless steel perforated mesh sheet
employs advanced punching techniques. High - precision CNC punching
machines are utilized to ensure accurate hole positioning and
consistent hole quality. The punching process can be adjusted
according to the specific requirements of hole shape, size, and
density. For complex hole patterns, computer - aided design (CAD)
software is used to create detailed punching templates, which are
then translated into instructions for the punching machines. After
punching, the edges of the board are carefully deburred to remove
any sharp edges, ensuring safety during handling and installation.
Additionally, for some special requirements, processes such as
bending, rolling, and welding can be applied to further shape the
mesh board.
4. Performance Advantages
- High Strength and Durability: Due to the inherent strength of 304 stainless steel, the
perforated mesh board exhibits excellent load - bearing capacity.
It can withstand significant mechanical stress, making it suitable
for applications where structural stability is crucial, such as
industrial platforms and heavy - duty partitions.
- Corrosion and Rust Resistance: As mentioned, the unique alloy composition provides superior
protection against corrosion. This makes the board ideal for
outdoor applications, coastal areas, and industries with high
humidity or exposure to chemicals, ensuring a long service life
with minimal maintenance.
- Ventilation and Filtration: The precisely designed hole patterns allow for efficient air and
fluid flow, making it an excellent choice for ventilation systems,
air filters, and sieving applications in industries like food
processing, pharmaceuticals, and chemical engineering.
- Aesthetic Appeal: The clean and uniform appearance of the perforated pattern,
combined with the sleek surface of stainless steel, gives the board
an attractive look. It can be used in architectural applications
for decorative facades, interior partitions, and furniture design,
adding a modern and stylish touch to the space.
5. Surface Treatments
To further enhance the performance and appearance of the 304
stainless steel perforated mesh board, various surface treatments
are available:
- Polishing: A polishing treatment can create a mirror - like finish,
significantly improving the aesthetic appeal of the board. It also
makes the surface easier to clean and more resistant to dirt and
stains, which is beneficial for applications in the food and
medical industries.
- Brushing: Brushed finish gives the board a textured, satin - like
appearance. This treatment can hide minor scratches and
fingerprints, making it a popular choice for architectural and
decorative applications where a more understated look is desired.
- Powder Coating: Powder coating provides a wide range of color options, enhancing
the board's visual appeal while also adding an extra layer of
protection against corrosion and abrasion. It is suitable for both
indoor and outdoor applications where color - matching or
additional protection is required.
- Anodizing: Although less common for stainless steel, anodizing can be
applied to create a hard, durable oxide layer on the surface,
improving wear resistance and providing a unique color finish.
6. Application Fields
- Architecture and Construction: Used as building facades, sunscreens, balcony guards, interior
partitions, and decorative panels, adding both functionality and
aesthetic value to buildings.
- Industrial Applications: Employed in factories for machine guards, ventilation systems,
noise barriers, and industrial sieves. It is also used in the
automotive industry for engine cooling, air intake grilles, and
exhaust shields.
- Filtration and Separation: Ideal for applications in the food processing, pharmaceutical,
chemical, and water treatment industries, where it is used for
filtering, sieving, and separating materials based on size and
particle characteristics.
- Furniture and Interior Design: Incorporated into furniture design, such as room dividers,
cabinet doors, and table tops, providing a modern and stylish look
while maintaining functionality.
