Perforated Corten Steel Screen for Architectural Use refers to customized weathering steel screen panels used for building exteriors, sunshades, ventilated screens, entrance partitions, and architectural facades.
Manufactured through CNC punching, fiber laser cutting, bending, welding, and surface treatment, these screens can be produced with different hole diameters, spacing, patterns, and supporting structures.
Gnee provides weathering steel materials and custom architectural screen fabrication services, from steel sheet sourcing and perforation to frame assembly, pre-rusting, inspection, export packing, and international shipping.
Perforated Corten Steel Screen Specifications for Architecture
Architectural perforated screens should be designed according to their installation location, panel dimensions, perforation layout, supporting structure, and required wind resistance.
Architectural Screen Specifications
| Parameter | Specification / Quotation Range |
|---|---|
| Material | SPA-H / S355J0WP / ASTM A588 |
| Steel Thickness | 1.5 / 2 / 3 / 4 / 5 / 6 mm |
| Standard Panel Examples | 1000 × 2000 / 1200 × 2400 mm |
| Large Panel for Evaluation | 1500 × 3000 mm |
| Round Hole Examples | Ø5 / Ø10 / Ø20 / Ø30 / Ø50 mm |
| Large Laser-Cut Openings | Ø80 / Ø100 / Ø150 mm or larger |
| Design Opening Ratio | 15–50% |
| Panel Structure | Flat / Folded / Framed |
| Surface Finish | Mill Finish / Pre-Rusted / Painted |
| Mounting | Brackets / Steel Frames / Bolted Connections |
These are proposed fabrication and quotation specifications. Maximum manufacturable dimensions require confirmation against the actual factory equipment and approved drawings.
CNC Punching Machine for Perforated Corten Steel Screen
Gnee provides CNC punching services for architectural weathering steel screens with regular round, square, and slotted holes. For repeated architectural screen patterns, CNC punching enables consistent hole placement and is suitable for batch orders with identical specifications.
CNC Punching Processing Data
| Processing Parameter | Proposed Fabrication Scope |
|---|---|
| Steel Thickness | 1.5–3 mm for common screens |
| Thicker Steel | 4–6 mm, subject to tooling |
| Panel Size | 1200 × 2400 mm |
| Round Hole Examples | Ø5 / Ø10 / Ø15 / Ø20 / Ø30 mm |
| Large Round Hole | Ø50 mm, subject to punching force |
| Hole Layout | Straight / 60° Staggered |
| Design Open Area | 15–50% |
Our fabrication service includes customized hole spacing, solid margins for bending and mounting, deburring, and panel leveling.
For larger openings or irregular screen patterns, we can evaluate fiber laser cutting as an alternative.
Fiber Laser Cutting for Custom Architectural Corten Steel Screens
For architectural screens requiring large circular openings, irregular geometry, company logos, or customized perforation patterns, Gnee provides drawing-based laser cutting services.
Laser Cutting Fabrication Data
| Parameter | Quotation Reference |
|---|---|
| Screen Thickness | 1.5–6 mm |
| Panel Size | 1200 × 2400 mm |
| Large Panel Request | 1500 × 3000 mm |
| Round Opening Examples | Ø20 / Ø50 / Ø80 / Ø100 / Ø150 mm |
| Pattern Types | Geometric / Irregular / Custom Graphics |
| Drawing Formats | DXF / DWG / PDF |
| Additional Services | Cut Edges / Mounting Holes / Panel Numbering |
Compared with punching, laser cutting provides more flexibility for irregular and large openings without separate punching dies.
The minimum bridge width between openings and the remaining material around mounting points must be checked before production.
CNC Bending and Frame Fabrication for Architectural Screens
Gnee provides CNC bending and forming services for Perforated Corten Steel Screen for Architectural Use, including folded panel edges, reinforced sections, and mounting flanges.
CNC Bending and Frame Specifications
| Processing Item | Fabrication Reference |
|---|---|
| Steel Thickness | 1.5–6 mm |
| Standard Bending Length Example | 2400 mm |
| Longer Bending Request | 3000 mm, subject to machine verification |
| Fold Angle Examples | 45° / 90° / 135° |
| Flange Width Examples | 20 / 30 / 50 mm |
| Steel Frame Examples | 40 × 40 × 2 / 50 × 50 × 3 mm |
| Mounting Hole Examples | Ø10 / Ø12 / Ø14 mm |
Our fabrication options include L-shaped, U-shaped, and Z-shaped bends, welded backing frames, connection plates, and mounting brackets.
For perforated architectural screens, a suitable unperforated bending margin should be reserved to reduce hole deformation and preserve the required connection strength.
Pre-Rusting and Surface Finishing Equipment for Architectural Corten Steel Screens
Gnee supports surface preparation and pre-rusting services for architectural weathering steel screen components. Processing options include abrasive blasting where required, surface cleaning, controlled spray treatment, drying, and specified protective coatings.
Available finishes include mill finish, pre-rusted appearance, and painted surfaces. For exterior building installations, adequate ventilation and water drainage must be considered. Weathering steel should not be installed where moisture remains trapped behind the panels or where early rust runoff can damage surrounding materials.
Opening Ratio and Weight Calculation of Perforated Corten Steel Screens
The opening ratio influences panel weight, visual transparency, and the amount of remaining material. For example, a 1200 × 2400 × 3 mm steel screen has a theoretical solid-sheet weight of approximately 67.82 kg, based on a nominal steel density of 7,850 kg/m³.
Weight at Different Opening Ratios
| Opening Ratio | Theoretical Steel Weight |
|---|---|
| 0% | 67.82 kg |
| 20% | 54.26 kg |
| 30% | 47.48 kg |
| 40% | 40.69 kg |
| 50% | 33.91 kg |
These weights assume the specified opening ratio applies to the full panel area. Real finished panels may be heavier because of unperforated edges, frames, mounting brackets, and stiffeners.
The opening ratio must not be used alone to determine wind-load resistance or structural safety.
