Product Code: L12TM5
​Type: Ultra-Heavy Trench Mesh (Extra-Wide Configuration)
​Compliance: AS/NZS 4671 | ACRS Certified | ISO 1461 (Galvanized Option)

Technical Specifications:

Key Features:

1. ​Extreme Load Distribution​

   • ​5-wire configuration​ engineered for ​400mm trench widths, supporting AS 5100.5 bridge loading standards.
   • ​40% higher torsional resistance​ vs. L12TM4, ideal for seismic zones (AS 1170.4 compliance).

2. ​Industrial-Grade Durability​

   • ​12mm high-yield steel​ (500MPa tensile strength) with ​4,500N/mm² weld strength​ (AS/NZS 1554.3).
   • Hot-dip galvanized variant achieves ​90μm coating thickness​ (AS/NZS 4680) for offshore/mine environments.

3. ​Smart Manufacturing​

   • AI-driven welding robots ensure ​​±0.8mm dimensional precision​ and defect-free joints.
   • Embedded NFC chips enable real-time tracking of:
     • Steel batch origins
     • Carbon footprint metrics (GBCA Green Star MAT-6)
     • Site-specific installation guidelines.

4. ​Corrosion Defense System​

   • Optional ​triple-layer epoxy coating​ (ISO 21809-3) for chemical/abrasion resistance.
   • UV-stable polymer edge guards prevent handling damage.

Typical Applications:

• ​Mega Infrastructure:
  • Suspension bridge anchor block foundations
  • Deep excavation basements (>6m depth)
  • Offshore wind turbine monopile trenches
• ​Heavy Industry:
  • Steel plant blast furnace footings
  • Mining haul road underlayments
  • LNG terminal cryogenic pipe trenches
• ​Precast Systems:
  • Mega-culvert segments (≥3m span)
  • Subsea tunnel linings with tidal load resistance

Ordering Notes:

❗ ​Customization:

• Available in ​5.4m–15m lengths​ (minimum 25 units for non-standard sizes).
• Galvanized orders require ​30-day lead time​ (including salt-spray testing).

❗ ​Logistics:

• ​Heavy transport mandatory​ – units exceed standard flatbed weight limits (consult ARC logistics team).
• Climate-controlled storage recommended for epoxy-coated variants.

❗ ​Compatibility:

• Requires ARC ​TMC12400 heavy-duty clips​ (sold separately) for 650MPa joint integrity.
• Pair with ​PODSPA6 spacers​ for 100mm+ concrete cover applications.
