Arming Urban Underground Arteries with "Safety Armor"
Luzhongbao EN124 Ductile Iron Manhole Cover Solutions Launch at VIETBUILD HCMC 2025
June 25-29, 2025 | Booth A2-634
Subtitle: The Overlooked Ground Defense
As Vietnam accelerates urbanization, manhole covers bearing over 30kg/cm² serve as the first line of defense for road safety.
—Yet according to the Vietnam Infrastructure Association, road accidents caused by cover failures surged 17% YoY in 2024.
Luzhongbao’s Mission
To engineer ductile iron cover systems for Southeast Asia that deliver Zero-Settlement, Zero-Theft, Zero-Pollution – exceeding EU EN124 standards.
I. Technical Foundation: The 30-Year Maintenance-Free Promise
At Booth A2-634, witness three breakthrough technologies:
1. Molecular-Level Structural Reinforcement
Rare earth magnesium alloy nodularization creates dense spherical graphite structures within the iron, achieving 550 MPa tensile strength (20% above EN124’s highest class). Eliminates structural fractures under heavy truck loads.
2. Climate-Adaptive Protective Coating
- Base Layer: ≥80μm hot-dip zinc resists electrochemical corrosion
- Surface Layer: Polyurethane elastomer withstands mechanical abrasion
- Third-party tests confirm ＞95% coating integrity after 5 years in simulated HCMC monsoon conditions.
3. The Silent Guardian
Patented T-shaped rubber gasket + ductile iron base form a dual damping system, reducing vehicle transit noise to ＜62 dB (meeting residential night-time standards).
II. Innovations for Vietnam’s Challenges
Monsoon Edition: 35% enlarged drainage pores – 2x faster water clearance (verified under 120mm/h downpours)
Industrial Zone Upgrade: Anti-slip edge grooves prevent forklift-induced displacement
Cultural Customization: Surface reliefs of city flowers, emblems, or cultural symbols
III. Exhibition Engagement Toolkit
Lifecycle Cost Analysis Service
Bring project parameters to our booth for:
10-Year Maintenance Cost Simulation (vs. traditional covers)
Carbon Footprint Assessment (95% ductile iron recyclability)
IV. An Open Letter to Municipal Engineers
When you ask:
“How to reduce public cover theft?”
Our solution: Triple-point mechanical locks + GPS chip slot – theft rate reduced to 0.3 cases/1,000 units/year.
“How to prevent cover displacement during typhoons?”
Our answer: F900-class covers weighing 80kg – require ＞5-ton impact force to move.

Closing Statement
Beneath the cover flows the city’s lifeblood.
Above it lies the people’s safe passage.
Luzhongbao honors its safety covenant with iron-clad resolve –
To forge roads that endure millions of heavy crossings,
To guard cities with silent vigilance.
Join us at Booth A2-634, June 25–29, 2025
To lay the foundation of urban safety.
