Steel Spine · Eternal Load-Bearing  

Luzhongbao EN124 Ductile Iron Manhole Covers: The Ultimate Pledge  

VIETBUILD HCMC 2025 | Booth A2-634 | June 25-29  

Prologue: Engineering Philosophy Forged by Time  

Silent for 20 years in Arctic Circle permafrost. Bearing 100,000 revelers at World Cup stadiums.  

True safety needs no fanfare.  

Luzhongbao delivers Southeast Asia’s mega-infrastructure a 30-year maintenance-free legacy through ductile iron DNA.  


I. Redefining Material Performance Limits  

1. Molecular-Level Strength Revolution  

  •    Tensile strength >600 MPa (28% above EN124’s highest class)  
  •    Rare >10% elongation – absorbs impact via micro-deformation, not fracture  
  •    Proven in Siberia: 92% impact energy retention at –50°C  

2. Quadruple Corrosion Defense  

  •    ① 99.92% pure ductile iron matrix resists intergranular corrosion  
  •    ② 100μm hot-dip zinc barrier against electrochemical erosion  
  •    ③ Epoxy resin seals micro-pores  
  •    ④ Polyurethane elastomer surface withstands mechanical wear  
  •    Vietnam salt-fog test result: <0.2mm corrosion depth after 20 years  

3. Silent Security Evolution  

  •    Triple-point mechanical locking: 300% theft resistance  
  •    Patented T-shaped rubber damping: <62 dB traffic noise (meets residential night standards)  

II. Extreme Scenario Tailoring for SE Asia  

Deep-Sea Port Edition  

F900-grade reinforcement array withstands gantry crane loads  

Laser-clad tungsten carbide layer: 8x wear life  

Highland Highway Solution
