A square hole perforated metal sheet is made by punching or CNC processing a flat metal sheet to create clean, evenly spaced square openings. It’s a popular choice among perforated metal sheets for projects that need a modern look, consistent airflow, and reliable strength.
Available specifications:
For engineering drawings, we can match hole size, pitch (center-to-center spacing), edge margins, and layout (straight-row or staggered) to your target open area percentage.
Length: 10mm – 4000mm (customizable)
Width: 10mm – 1500mm (customizable)
Thickness: 0.2mm – 12mm, depending on application
Material: stainless steel (common for corrosion resistance), carbon steel (cost-effective), galvanized steel (outdoor use), aluminum (lightweight), plus copper and other alloys upon request
Hole Type: Standard square hole, rectangular hole, or customized shapes
Hole Size: 2mm – 300mm (square side length or rectangular dimensions), with the minimum hole size confirmed based on sheet thickness and tooling
Key Features of Square Hole Perforated Metal Sheet: consistent openings for predictable airflow and visibility, a clean geometric appearance, and a strong sheet structure that’s easy to fabricate. If your project is comparing different perforated sheet metal options, square holes are often chosen for their modern look and straightforward layout.
Perforated Metal Sheets with Square & Rectangular Hole Patterns
Problem: Limited sheet specifications on the market
Buyers often cannot find the exact thickness or hole size.
Solution: We provide custom square hole perforated metal sheet production with flexible parameters.
Problem: Unreliable factories
Some suppliers use outdated equipment, causing quality issues.
Solution: Our CNC equipment guarantees precision and sheet flatness.
Problem: Additional processing needed after purchase
Many customers need bending, welding, or finishing elsewhere.
Solution: We offer one-stop perforated metal sheet processing from raw punching to finished product.
Square Hole Perforated Metal Sheets
Our Square Hole Perforated Metal Sheets can be further processed according to customer needs:
Bending – customized angles for installation
Welding – joining multiple sheets into larger panels
Rolling – cylindrical shaping for filters or mufflers
Laser Cutting – precise custom dimensions
Surface Treatment – galvanizing, powder coating (custom RAL colors), painting, anodizing (for aluminum), and other finishes for custom perforated metal projects
We can also provide deburring and edge finishing to improve handling safety and installation quality, especially for panels used in architectural or equipment enclosures.

Requirement Communication – drawings or parameters provided
Quotation – based on material, thickness, and hole size
Sample Making – prototype confirmation
Mass Production – CNC punching and strict quality check
Secondary Processing – bending, welding, or finishing
Packing & Delivery – safe packaging and timely shipment
If your project needs a different visual style or airflow behavior, you can also compare round hole perforated metal sheets, slotted perforated metal sheets, or hexagonal hole perforated metal sheets.
Square Hole Perforated Metal Sheet is widely used across multiple industries:
Architecture: wall cladding, ceilings, building facades, and custom perforated panels for screens and feature walls
Industrial: filtration mesh, machine guards, ventilation covers
Transportation: sound barriers, fencing, protective panels
Household: speaker grills, kitchen filters, lighting covers
Agriculture: ventilation panels, grain storage bins, livestock enclosures
For acoustic builds, square-hole panels are often paired with sound-absorbing backing; for very small-hole acoustic designs, consider micro perforated metal sheets.

Q1: Can I order samples or a small quantity?
A: Yes. We support sample approvals and small trial orders, as well as bulk production. Share your material, thickness, hole size/pitch, and sheet size for a quick quote.
Q2: What’s the typical lead time?
A: Standard items usually ship in 3–7 days. Custom patterns or added fabrication typically take 7–15 days after the drawing is confirmed.
Q3: How do you control flatness after perforation?
A: We use CNC punching and leveling to reduce distortion. For dense patterns or thinner gauges, we plan the process carefully and check flatness before packing.
Q4: What surface finishes are available?
A: Common options include galvanizing, powder coating (custom RAL colors), painting, and anodizing for aluminum. If you have an environment requirement, tell us and we’ll recommend a finish.
Q5: Which material is best for outdoor use?
A: Stainless steel is a reliable choice for corrosion resistance, and galvanized steel is a common option for outdoor projects with cost control. The best pick depends on your environment and service life target.
Q6: How do you pack for international shipping?
A: We typically use protective film and interleaving, edge protection, steel strapping, and wooden pallets (or crates if needed) to help prevent scratches and bending during transit.
Q7: I don’t have drawings—can you help with the specification?
A: Yes. Send your application, target sheet size, thickness range, and preferred hole size/open area. We can suggest a workable pattern and provide a simple drawing for approval.
Q8: Can these sheets be used for sound control projects?
A: Yes. They’re often used as a perforated facing when combined with acoustic backing. Open area and backing selection matter, and we can help you choose a suitable layout.
Q9: What payment methods do you accept?
A: We support T/T and L/C for international orders. If you have a preferred payment arrangement, let us know and we’ll confirm what works for the order.
Q10: Can you powder coat in custom colors?
A: Yes. We can powder coat in a wide range of RAL colors. Share the RAL code (and gloss level if needed) for confirmation.
Q11: Do you ship worldwide and provide export documents?
A: Yes. We export globally and can provide standard paperwork such as a packing list and commercial invoice, plus other documents as required by your country or forwarder.
Q12: How do I know the open area percentage?
A: Open area depends on hole size and pitch/layout. Share your parameters and we’ll calculate it for you, or use the Open Area & Weight Calculator tab on this page.
After perforation, especially for plates with very dense hole patterns, the perforated metal sheets will experience significant deformation. We perform flattening treatment after completing all perforation processes. Below is the video of flattening perforated metal sheets:
After the leveling process, our perforated metal sheets can be precisely laser-cut into any custom shape as required. Below is a production video demonstrating the laser-cutting process:
