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)
Proven Track Record: 15+ years of success in Middle East, European, and U.S. markets.
One-Stop Solution: End-to-end sheet metal services (design to delivery).
Global Compliance: ISO 9001, CE, FCC, UL, SABER, ESMA-certified.
Competitive Pricing: Direct factory costs (no middlemen).
Technical Support: Expert engineering team (consultation, optimization, problem-solving).
