Home - Custom Romboid Perforated Metal Sheets Durable & Precision-Cut
(perforated metal sheet romboid)
Perforated metal sheets with rhomboid patterns have become essential in architectural and industrial applications, offering 23% higher structural stability than standard hexagonal patterns according to ASTM E8-24 testing. These sheets combine geometric precision with functional porosity, enabling airflow rates of 40-65 m³/h while maintaining 85% load-bearing capacity. Leading suppliers now utilize CNC punching machines with ±0.15mm dimensional accuracy to ensure pattern consistency across batches.
Advanced manufacturers employ cold-rolled steel (CRS) and aluminum alloys (5052/H32) with thicknesses ranging from 0.5mm to 12mm. The table below compares performance metrics:
| Material | Tensile Strength (MPa) | Open Area Ratio | Corrosion Resistance |
|---|---|---|---|
| 304 Stainless | 520-680 | 15-70% | Salt Spray 1000h |
| Aluminum 6061 | 124-290 | 20-65% | Atmospheric 25y |
| Galvanized Steel | 340-420 | 10-60% | Zinc Coating 80μm |
The global market features three primary supplier types:
Top-tier factories implement ISO 9001:2015-certified processes with automated optical inspection (AOI) systems achieving 99.2% defect detection. Multi-stage tooling ensures rhomboid apertures maintain ±2% dimensional stability across temperature fluctuations from -40°C to 300°C.
Engineered solutions typically include:
A recent automotive project utilized 1.2mm thick rhomboid-perforated aluminum (6082-T6) achieving:
When evaluating perforated metal sheet romboid
suppliers, prioritize manufacturers with:
(perforated metal sheet romboid)
A: Perforated metal sheets with rhomboid patterns are typically made from stainless steel, aluminum, or carbon steel. These materials offer durability, corrosion resistance, and adaptability for industrial or architectural applications.
A: Yes, manufacturers often provide customization for hole size, sheet thickness, and overall dimensions. Suppliers work with clients to meet specific project requirements.
A: Common applications include construction (ventilation, facades), automotive (filters), and industrial machinery (safety guards). The design balances aesthetics and functional airflow or filtration needs.
A: Check certifications like ISO 9001, request material test reports, and review customer testimonials. Reputable factories often provide samples for quality assessment.
A: Pricing depends on material grade, sheet thickness, hole density, and order volume. Bulk orders from specialized factories often reduce per-unit costs.
