SS 316L Perforated Sheets

If you are looking for a perforated metal sheet for corrosion resistance, hygiene and easy fabrication, SS 316L perforated sheets are your trusted choice for marine, pharmaceutical, food processing and construction fields. All sheets produced by GNEE are manufactured in accordance with international standards, stainless steel 316L perforated sheets meet ASTM, ASME, JIN, DIN and other standards, with a wide range of sizes from 1000mm to 3500mm, thickness from 4mm to 100mm, and length from 2000mm to 6000mm. Custom orders are also accepted to meet the project needs of each customer.

316L stainless perforated sheet

316L perforated sheet offers far superior resistance to chloride-induced and intergranular corrosion compared to standard stainless steels. Even after perforation, the edges maintain excellent resistance against seawater, acids, and alkalis, delivering a service life up to 3 times longer than 304 perforated sheets.

The perforated SS 316L sheet with round holes has a tensile strength ≥485 MPa. With optimized hole alignment, it can support loads of 5–8 tons per square meter, making it ideal for equipment guards, load-bearing platforms, and other high-strength applications. Its performance remains stable across a wide temperature range from -196°C to 800°C, with a typical service life of 15–20 years. Over its full lifecycle, maintenance costs are up to 60% lower than perforated carbon steel sheets.

We offer perforated sheets with round, square, slotted, and custom-designed hole patterns, featuring hole diameters ranging from 0.5 mm to 20 mm and open area ratios between 20% and 60%, with dimensional tolerances strictly controlled within ±0.05 mm. All products are supplied with EN 10204 3.1/3.2 material certificates and support PMI (Positive Material Identification) verification to ensure full material traceability.

316L vs 304 Perforated Stainless Steel Sheet

When choosing between 316L and 304 perforated stainless steel sheets, the primary differentiator is corrosion resistance. Grade 304 is ideal for general-purpose indoor or dry-air environments, while 316L is a premium, marine-grade option designed to resist aggressive pitting from chlorides, brines, and chemical exposure.

 

316L Perforated Plate Applications

Open Area (%)	Typical Application
20% – 30%	Structural panels, machine guards
30% – 45%	Architectural facades, acoustic panels
45% – 60%	Filtration systems, ventilation panels
Above 60%	High-airflow and lightweight applications

 

Why Choose GNEE 316L Perforated Sheets

At GNEE, every sheet of ASTM A240 316L perforated stainless steel undergoes a comprehensive quality control process to ensure consistent performance and full traceability. All products are supplied with EN 10204 3.1/3.2 Material Test Certificates (MTC); for critical projects, we can also arrange SGS or other third-party inspection services upon customer request.

 

packaging and shipping

Protective Film Application (PE/Laser Film): If the perforated sheets require a specific surface finish (such as 2B, brushed, or mirror finish), we apply a single or double layer of PE protective film to prevent scratches during processing and transportation.
Depending on the cargo weight and shipping method, we offer the following two options:
Option A: Fumigation-free Wooden Pallets: Suitable for bulk shipments of flat-stacked sheets. The pallets feature reinforced bases to facilitate forklift handling.
Option B: Reinforced Wooden Boxes (Export-grade): Suitable for small-sized, high-precision, or high-specification 316L perforated sheets. These boxes provide comprehensive, all-around protection, making them the safest choice for long-distance ocean transport.

FAQ

Is 316L perforated plate suitable for seawater environments?

Yes, 316L perforated plate is highly suitable for general marine and coastal environments (such as splash guards, ventilation panels, and coastal railings), but it is not recommended for fully submerged, stagnant seawater applications without additional coatings.

Can 316L perforated plate be welded?

Yes, 316L perforated plate can be easily welded. In fact, the "L" stands for "low carbon," which is intentionally formulated to prevent intergranular corrosion and material sensitization during welding.

What is the price of 316L perforated plate?

 The price of a 316L perforated stainless steel plate varies widely based on thickness, dimensions, hole pattern, and order volume. For small, cut-to-size sheets, retail prices range from $40 to over $600 per piece. For bulk or industrial orders, prices generally range from $3.00 to $7.00 per pound.
