Perforated Corten Steel Fence for Landscaping is a custom weathering steel fencing solution used for garden boundaries, landscape privacy screens, residential courtyards, parks, and commercial outdoor spaces.
Made from weathering steel sheets, Corten Perforated Steel Fence Panels can be manufactured with round holes, square perforations, slotted openings, and laser-cut decorative patterns. The panels can be combined with steel posts, welded frames, mounting brackets, and pre-rusted surface finishes.
Gnee offers project-based fabrication services covering weathering steel material sourcing, CNC punching, laser cutting, bending, welding, surface treatment, fence accessories, export packaging, and international delivery.
Specifications of Perforated Corten Steel Fence Panels
The thickness, hole arrangement, opening ratio, and frame design should be selected according to the fence height, span between posts, privacy requirements, and local wind loads.

CNC Punching for Perforated Corten Steel Fence Panels
Gnee offers CNC punching services for Perforated Corten Steel Fence Panels with uniform round holes, square holes, and slotted patterns.
For standard landscape fencing projects, our proposed CNC punching specifications include:
| Processing Item | Proposed Capability |
|---|---|
| Steel Thickness | 2–6 mm |
| Panel Size | Up to 1500 × 3000 mm |
| Round Hole Diameter | Ø5–50 mm |
| Larger Round Holes | Ø60–80 mm, subject to machine capacity |
| Opening Ratio | 15–50%, subject to design review |
| Hole Arrangement | Straight, 45° or 60° staggered |
Our fabrication services include custom hole spacing, panel edge margins, mounting holes, deburring, and leveling.
CNC punching is especially suitable for bulk production of garden fencing with repeated perforation patterns. For larger holes that exceed the machine's punching force or die capacity, laser cutting is recommended.
Laser Cutting for Decorative Corten Steel Garden Fences
For garden fences requiring leaf patterns, tree silhouettes, geometric shapes, or large circular openings, Gnee provides drawing-based fiber laser cutting services.
Compared with conventional punching, laser cutting allows more flexible customization of decorative fence designs without a dedicated punching die for every pattern.
Laser Cutting Capabilities for Fence Panels
| Processing Item | Proposed Capability |
|---|---|
| Steel Thickness | 2–12 mm |
| Panel Size | Up to 1500 × 3000 mm |
| Round Opening Examples | Ø30, Ø50, Ø80, Ø100, Ø150 mm |
| Larger Openings | Evaluated according to drawings |
| Pattern Types | Leaves, branches, geometric designs, logos |
| Drawing Formats | DXF, DWG, PDF |
We can manufacture custom perforated panels with mounting slots, decorative cutouts, and finished external profiles.
For large landscape projects, repeated patterns can be produced across multiple fence panels, with panel numbering to support installation.
CNC Bending for Corten Steel Fence Panel Reinforcement
Gnee provides CNC bending services to produce folded edges and reinforced profiles for Perforated Corten Steel Fence Panels.
For reference, fence panels with 2–6 mm thickness and up to 3000 mm bending length can be evaluated for L-shaped, U-shaped, and Z-shaped folded structures.
Typical fabrication options include 90° folded edges, reinforced side returns, and frame connection details.
For a 1800 mm high garden fence, the panel may be designed with folded edges or an additional frame to improve rigidity. The final bending dimensions and supporting structure depend on the panel width, perforation ratio, and installation loads.
Welding and Assembly of Perforated Corten Steel Fence Systems
In addition to perforated panels, Gnee provides fabrication services for fence frames, posts, base plates, and mounting accessories. Our welding and assembly services cover MIG/MAG welding, frame fabrication, steel tube cutting, drilling, and connection plate processing.
Custom Fence Components
| Component | Reference Specifications |
|---|---|
| Perforated Fence Panel | 2–6 mm thick |
| Square Fence Posts | 60 × 60 / 80 × 80 / 100 × 100 mm |
| Post Wall Thickness | 3–5 mm |
| Rectangular Frame Sections | 40 × 20 / 50 × 30 mm |
| Frame Wall Thickness | 2–3 mm |
| Mounting Holes | Ø10 / Ø12 / Ø14 mm |
| Base Plates | Custom size and thickness |
| Fence Height Examples | 1200 / 1500 / 1800 / 2000 mm |
These are quotation examples, not verified stock dimensions or an approved structural design. We can supply perforated panels only or coordinate a complete fence package with numbered panels, posts, mounting brackets, base plates, and fasteners.
Fence posts and supporting frames should be selected based on installation height, post spacing, wind loads, ground conditions, and local building requirements.
Pre-Rusting and Surface Finishing for Corten Garden Fences
Gnee provides surface treatment services for Perforated Corten Steel Fence for Landscaping, including surface cleaning, abrasive blasting where necessary, controlled pre-rusting, and specified protective coatings.
Our surface preparation and finishing services can cover both the perforated panels and their fabricated fence components.
For pre-rusted orders, the required appearance should be confirmed using reference samples before bulk production. The panels are then inspected and packed with protective separation materials.
Proper installation is important. Weathering steel fences should avoid prolonged contact with soil, trapped moisture, or standing water. Drainage and ground clearance should be considered, especially near concrete paving and stone surfaces that may be stained by early rust runoff.
Hole Size and Opening Ratio for Perforated Corten Steel Garden Fences
The perforation size and opening ratio determine the visual openness and amount of remaining steel in a Corten Perforated Steel Fence Panel. For round holes arranged in a 60° staggered pattern:
Open Area (%) = 90.69 × (Hole Diameter / Center Pitch)²
Fence Perforation Design Examples
| Round Hole | Center Pitch | Theoretical Open Area |
|---|---|---|
| Ø5 mm | 15 mm | 10.08% |
| Ø10 mm | 20 mm | 22.67% |
| Ø20 mm | 35 mm | 29.61% |
| Ø30 mm | 50 mm | 32.65% |
| Ø50 mm | 80 mm | 35.43% |
| Ø80 mm | 120 mm | 40.31% |
Applications of Perforated Corten Steel Fence for Landscaping
