Product overview

Core functionalities

Applicable scenarios

Unique advantages

Directional Guidance: Equipped with DG3 reflective film for high-visibility signage, ensuring clear direction and exit information (e.g., city names and highway numbers) even in low-light conditions.
Durability & Weather Resistance: Constructed from extruded aluminum alloy and aluminum backing plates, designed to withstand harsh outdoor environments, extreme temperatures, and corrosion.

Key features

1. Corrosion-Resistant Extruded Aluminum Alloy Construction

With corrosion-resistant extruded aluminum alloy construction, ensure long-lasting durability in harsh outdoor environments. ~50% lighter than steel alternatives*

2. Enhanced Visibility with DG3 Reflective Film

With DG3-grade reflective film, achieve 30% brighter visibility compared to DG2-rated alternatives*, ensuring clear readability at night or in low-light conditions.

3. Superior Weather Resistance

With excellent weather resistance, maintain structural integrity and clarity in extreme temperatures and environmental exposure, outperforming non-treated materials*.

4. Large-Scale Highway Adaptability

Designed for large highway gantries, provide clear directional guidance at high speeds, ideal for continuous commercial traffic use compared to standard residential signage*.

5. EN62471 Safety Compliance

With EN62471 certification, ensure compliance with international photobiological safety standards, surpassing uncertified alternatives*

Supplier's note

Technical Breakthroughs:
- DG3 Reflective Film: Outperforms DG2-grade films by 20%, ensuring visibility at 500m+ distances.
- Aluminum Alloy Backing: 50% lighter than steel equivalents while maintaining structural integrity.
- EN62471 Compliance: Ensures safe light emission levels for driver comfort.
Version Selection Guide:
- Base Model: Ideal for standard highways with predictable traffic (e.g., rural routes).
- Advanced Model: Suitable for urban highways requiring moderate customization (e.g., frequent route updates).
- Pro Model: Best for high-traffic corridors or extreme climates (e.g., mountain passes), where durability and visibility are critical.

With the Pro Model’s DG5 film and 5mm alloy, you can achieve triple the reflectivity of industry benchmarks, enabling safe navigation even in heavy fog. Pair this with its corrosion-resistant material to reduce replacement costs by up to 40% over 10 years.

Product comparison

Category	Usage Scenarios	Characteristics	Advantages	Disadvantages
Material Composition	High-traffic urban/rural highways	Aluminum alloy (EN62471 certified) ▲ Base: 200 MPa tensile strength; Advanced: 300 MPa ▲ (ASTM E8 test)	Lightweight yet durable; corrosion-resistant (ISO 9227)	Higher cost than plastic variants; requires专业 installation tools.
Reflective Technology	Nighttime visibility-critical routes	3M DG3 reflective film (Class 3 retroreflectivity ≥ 700 cd·lx⁻¹·m⁻² at 0.2 luminance) ▲ Advanced: 900 cd·lx⁻¹·m⁻² ▲	Enhanced nighttime visibility (meets ASTM D4061); glare reduction.	More expensive than lower-grade films (e.g., DG2); UV degradation over time.
Weather Resistance	Coastal/industrial regions	Withstands 1000+ hours salt spray (ASTM B117) ▲ Base: 500 hours; Advanced: 1000+ ▲	Maintains structural integrity in corrosive environments.	Limited performance in extreme chemical exposure (e.g., acid rain).
Structural Integrity	High-collision-risk zones	Aluminum backing plate (thickness: Base 2mm, Advanced 3mm ▲ ISO 3801)	Enhanced durability against impacts (ASTM D3363 adhesion test).	Heavier installations may require reinforced mounting hardware.
Safety Certification	EU-regulated roadways	EN62471 compliant (no hazardous light emissions)	Meets EU safety standards for photobiological safety.	Certification adds to production costs; limited in non-EU markets.
Visibility Performance	Curved/multi-lane highways	240° viewing angle (▲ Advanced: 270° ▲)	Wider driver visibility (ISO 14263 compliance); reduces blind-spot risks.	Requires precise installation to avoid light distortion.
