Stainless steel perforated sheets are one of the most requested options in our perforated metal sheets lineup, available in a wide range of stainless steel grades.
including austenitic, ferritic and duplex stainless steels,
to meet different requirements for corrosion resistance, strength and fabrication.
From thin-gauge coils to heavy plate, we make perforated stainless steel in standard sheet sizes or cut-to-size blanks. If you’re quoting a project, send the grade, thickness, hole pattern, and any fabrication needs (cutting, bending, welding), and we’ll confirm manufacturability before pricing.
In search of a durable, versatile and decorative metal sheet solution?
Our stainless steel perforated metal sheets combine strength, They’re often specified as architectural screens and perforated panels where appearance, airflow, and durability all matter.
corrosion resistance and design flexibility,
making them suitable for architectural, industrial and decorative applications.
Stainless steel perforated sheets can be produced in different stainless steel grades, If you’re choosing between grades: 304/304L is the go-to for most indoor/outdoor projects, 316/316L is preferred for coastal, chemical, and wash-down environments, and 430 is a cost-effective option for indoor use where high corrosion resistance isn’t critical.
allowing engineers and buyers to select the most suitable material
based on corrosion resistance, mechanical strength and cost requirements.
304 and 304L stainless steel perforated sheets are the most commonly used grades,
offering a good balance of corrosion resistance, formability and surface appearance.
They are widely used in architectural panels, interior decoration,
filtration systems and general industrial environments.
316 and 316L stainless steel perforated sheets contain molybdenum,
providing higher corrosion resistance than 304 stainless steel.
They are recommended for marine, chemical, food
and pharmaceutical applications.
430 stainless steel perforated sheets are ferritic stainless steels
with magnetic properties and moderate corrosion resistance.
They are a cost-effective option for indoor decorative panels
and equipment enclosures.
Other stainless steel grades, including 201, 321, 347, duplex 2205, Material traceability documents (such as mill test reports) can be provided upon request for project documentation.
and special alloys, are available on request.
Stainless steel perforated metal sheet hole pattern display
Stainless steel perforated sheets can be manufactured with various hole types
to meet different functional, structural and aesthetic requirements.
Hole shape selection affects open area, strength, Beyond hole shape, layout matters. Buyers usually specify hole diameter plus pitch (center-to-center spacing) and the arrangement (straight or 60° staggered/triangular pitch). These choices drive open area, rigidity, and how the sheet looks at a distance.
airflow performance and overall appearance.
Round hole perforated sheets are the most common option,
providing a good balance of strength, open area and manufacturing efficiency.
They are widely used for filtration, ventilation and screening applications.
Square hole perforated sheets offer a modern, structured appearance
with higher open area compared to round holes of similar spacing.
They are commonly used in decorative and architectural projects.
Slotted hole perforated sheets allow directional airflow
and material passage while maintaining structural strength.
They are suitable for screening, drainage and industrial processing.
Hexagonal hole perforated sheets, also known as honeycomb perforated sheets,
provide high open area and efficient material flow.
They are commonly used in filtration and processing industries.
Decorative and custom hole patterns can also be produced according to drawings or design requirements
according to drawings or design requirements,
mainly for architectural facades and interior decoration.
We manufacture and supply stainless steel Perforated Metal Sheets in both industrial and decorative grades. Available in full sizes or custom hole patterns, these sheets can be tailored to your project requirements with precision processing and a wide range of surface finishes.
