Comprehensive mathematical parameters and tolerances for industrial perforated materials.
To optimize air flow, dust separation, or acoustics in civil works, choosing the correct opening area ratio is critical. Below are the key mathematical formulas used by our CNC design engineers to verify material stability before metal stamping:
Provides the highest mechanical strength and structural load balance. Used extensively in filtration and grain sieving.
Where D = Hole Diameter, P = Pitch (distance between hole centers).
Provides the maximum ventilation and direct lines of sight. Ideal for security screens, structural enclosures, and architectural guards.
Where W = Hole Width, P = Pitch.
| Material Type | Available Thickness | Hole Type Geometry | Post-Processing Treatments | Target Applications |
|---|---|---|---|---|
| Stainless Steel (304, 316, 316L) | 0.4mm – 12.0mm | Round, Square, Slotted, Hexagonal | Pickling, Passivation, Electro-polishing | Jakarta Wastewater, Chemical Processing, Marine Grating |
| Galvanized & Galvalume Steel | 0.5mm – 6.0mm | Round, Slotted, Star, Custom | Zinc coating thickness up to 275g/m² | HVAC Ducting, Structural Decking, Cable Trays |
| Aluminum Alloys (1060, 3003, 5052) | 0.8mm – 10.0mm | Decorative patterns, Hexagonal | Anodizing, Powder Coating, PVDF coating | SCBD Office Cladding, Sunshades, Interior Ceilings |
| Carbon Steel (Q235B, ASTM A36) | 1.0mm – 20.0mm | Heavy round, square punch | Hot-Dip Galvanizing, Primer painting | Mining Vibrating Screen, Heavy Anti-Skid Planks |

Targeted material solutions engineered to resolve complex local infrastructure challenges.
Commercial structures in Jakarta’s Golden Triangle (Kuningan, Sudirman, Thamrin) face intense tropical thermal loads. Our PVDF-coated aluminum perforated facades provide optimal solar shading, reducing building HVAC energy requirements by up to 25% while maintaining architectural ventilation and aesthetic values.
Operating in the high-demand environments of West Java’s industrial centers, our precision SS316 perforated screen plates resist chemical oxidation. Engineered with micro-hole openings down to 0.5mm, these plates provide reliable long-term filtration in petrochemical refineries, wastewater plants, and pulp processing facilities.
For maritime platforms and offshore loading installations near Jakarta Bay, structural safety is critical. Our Crocodile-Teeth and round embossed anti-skid safety grating sheets prevent slips in high-grease, wet, or marine environments, offering superior shear stability under heavy loads.
High-precision custom items designed for complex industrial machinery and automotive engines.
We leverage our strategic geographic location in Ningbo, home to one of the world's premier deep-water container ports. We coordinate direct marine routes to Tanjung Priok, Jakarta, guaranteeing optimized shipping timetables and minimal lead times.
Our expert export team manages full compliance reporting, offering complete documentation packs including Mill Test Certificates (MTC), Certificate of Origin (Form E for China-ASEAN FTA tariff exemptions), and full structural test data to help you clear customs seamlessly.
Each sheet produced under our manufacturing umbrella is subjected to intensive structural validation. Our testing procedures cover:
| Flatness Testing | Post-punch tension leveling verification using high-precision digital gauges. |
| Hole Consistency | Optical sensor arrays check pitch alignment and dimensional tolerance compliance. |
| Corrosion Testing | Accelerated salt spray chambers confirm finish performance on coatings. |
