Custom Sheet Metal Solutions for Outdoor Digital Signage
Understanding Outdoor Digital Signage Requirements
Outdoor digital signage operates in extreme environments—scorching heat, heavy rain, dust storms, etc. Unlike indoor displays, outdoor units require weatherproofing, dust resistance, and temperature resilience for reliable performance. Key requirements include:
-
Environmental Protection:
- IP65/IP66 ratings (IP65 for basic weather resistance; IP67+ for heavy rain/coastal areas)
- IK10 impact resistance (withstands 20J mechanical impact)
- NEMA 4/4X specifications for outdoor use
-
Temperature Performance:
- Operating range of -30°C to 50°C (specialized models extend to -40°C to 60°C)
- 60°C heat tolerance for Middle East applications
- Advanced cooling systems (intelligent temperature control, high-efficiency fans)
-
Material Standards:
- 6063-T5 aluminum (10–15-year lifespan) or 316 stainless steel (for saltwater environments)
- Hot-dip galvanized steel with surface roughness of 30μm–35μm
- Anti-glare glass (transmittance >97%, reflectivity <3%)
Our Comprehensive Sheet Metal Solutions
Sanjun delivers end-to-end sheet metal solutions for outdoor digital signage manufacturers and integrators:
1. Precision Sheet Metal Fabrication
Our CNC equipment ensures dimensional accuracy within ±0.1mm, meeting stringent outdoor signage requirements. We specialize in:
- Complex panel fabrication for display enclosures
- Precision cut-outs for buttons, connectors, and ventilation
- Custom bending for aesthetic and functional designs
- Integrated mounting brackets and structural components
2. Weatherproof Enclosure Solutions
Water intrusion causes 65% of premature LED failures—even a 1mm unsealed gap can damage circuitry within 6 months. Our solutions include:
- Fully sealed aluminum enclosures with IP56/IP65/IP66 ratings
- Dual-sealing systems (butyl tape + silicone) reducing failure risk by 90%
- Stainless steel compression rings for cable entries
- UV-resistant powder coating (prevents fading 30% longer)
3. Thermal Management Solutions
LED modules lose 1% brightness per 100 hours above 85°C. Our thermal solutions include:
- Dual cooling fans (40–60 CFM airflow) and heat sinks (maintaining <75°C)
- Heat-resistant LCD panel mounting systems
- Intelligent temperature control
- Passive cooling designs for environments <35°C
4. Custom Surface Finishes
We offer diverse surface treatments for aesthetics and functionality:
- Powder coating (various colors/textures)
- Anodizing (corrosion resistance)
- Electroplating (decorative/protective)
- Specialized coatings (UV-resistant, anti-graffiti)
5. Structural Integrity Solutions
Our designs ensure stability against environmental stresses:
- 3mm-thick aluminum frames (withstanding 150km/h gusts)
