🏗️ Three Core Solutions

🅰️ Steel-UHPC Composite Bridge Deck

Designed for new long-span bridges. Deck stiffness improved by 50%, self-weight reduced by 30%, weld fatigue issues significantly reduced.

Construction period shortened from 3-6 months to 2-4 weeks. Service life extended from 15 years to 50-year maintenance-free. Validated on 30+ bridges.

📏 Pavement thickness 35-50mm

🅱️ NC-UHPC Composite Structure

Prestressed concrete body + UHPC bridge deck combination. Balances structural performance and economy.

Suitable for 20-50m medium-short span new bridges. Prestressed concrete reduces main body cost; UHPC solves bridge deck cracking and durability issues.

💰 Best Cost Performance

🔧 UHPC Bridge Rehabilitation

More reliable bonding with original concrete. Solves both bearing capacity and durability deterioration simultaneously.

Excellent fire resistance — carbon fiber fails in fire, UHPC does not. Wet-method on-site construction, no specialized equipment required.

🛠️ Minimal Disturbance to Existing Structure

🌊 Typical Projects

🌊 Shandong Peninsula Cross-Sea Bridge

UHPC bridge deck paving in coastal salt-fog corrosive environment. UHPC porosity <2%, chloride ion permeability coefficient <0.02×10⁻¹²m²/s.

50-year carbonation depth <1mm. Service life 8-10× longer than normal concrete.

🛣️ Multiple Medium-Small Bridges on Guangdong Coastal Expressway

Bridge rehabilitation, wet-method on-site construction, no specialized equipment needed. Construction period 60% shorter than conventional solutions.

Solves both insufficient bearing capacity and durability deterioration simultaneously.

🏭 A Certain Large-Span Steel Box Girder Bridge in Hunan

Steel-UHPC composite bridge deck, span >50m, deck stiffness improved by 50%.

Factory-prefabricated UHPC bridge decks, transported to site for lifting and assembly. Construction period approx. 3 weeks.

❓ Frequently Asked Questions

What is UHPC? How is it different from normal concrete?

UHPC (Ultra-High Performance Concrete) is made from cement, mineral admixtures, fine aggregates, steel fibers, and superplasticizers. 28d compressive strength reaches 100–230 MPa (normal C50 concrete only 50–55 MPa), flexural strength 20–40 MPa (approx. 3–8× C50), fracture energy 20–23 kJ/m² (approx. 200× C50). Especially suitable for bridge construction with 50+ year service life.

What are the advantages of Steel-UHPC Composite Deck over traditional steel bridge decks?

Deck stiffness improved 50%+; weld fatigue issues significantly reduced; pavement thickness reduced from 80mm to 35-50mm, self-weight reduced 30%+; service life extended from 15 years to 50-year maintenance-free.

How much does a UHPC bridge cost per square meter?

Comprehensive cost approx. 800-1,200 CNY/m² (excluding steel box girder). Long-term cost performance far exceeds conventional solutions. UHPC material unit price approx. 2,800-3,800 CNY/ton, usage only 1/4 to 1/3 of normal concrete.

What export certifications are available?

Certified to GB/T 31387-2015 (China), CE (EN 206), and ASTM C1856 (USA). English/French/Spanish technical documentation available. Supports international project bidding.
