L3T Telecommunication Manhole Cover – Technical Specifications & Solutions
1. Material & Structural Design
- High-Strength Materials: Manufactured from ductile iron (EN-GJS-500-7) , ensuring compressive strength ≥50 kN and long-term durability in harsh environments15.
- Custom Dimensions: Supports non-standard rectangular (e.g., 1200×800 mm) or circular (e.g., φ600 mm) designs to accommodate telecom cable layouts and underground infrastructure13.
2. Load Capacity & Safety Features
- L3T Load Rating: Compliant with EN 124 C250 standard (25-ton axial load), ideal for vehicular traffic zones and telecom trunk lines12.
- Anti-Theft Mechanisms: Optional triple-point locking systems or RFID-enabled smart locks to prevent unauthorized access17.
3. Customization Services
- Tailored Configurations: Custom drainage patterns, anti-slip textures (diamond/linear grooves), and laser-etched branding/logos per client specifications13.
- Rapid Prototyping: 3D modeling support with sample delivery in 10-15 business days15.
4. Certifications & Compliance
- ISO 9001-certified production, meeting ASTM A48 (cast iron) or ISO 2384 (composites) standards25.
5. Production & Logistics
- Flexible MOQ: Minimum order quantity of 0.5 tons, with FOB/CIF global shipping options
