Material: ASTM A709/A709M (ASTM International) structural steel (Grade 50/50W)

Durability: Professional anti-corrosion treatment, 100-year design service life

Product Positioning:Specially designed steel pile products for deep bridge foundations, hydraulic cofferdams, and bridge piers in high seismic zones, providing high load-bearing capacity and impact resistance. The range includes H-shaped steel piles, open and closed steel pipe piles, suitable for permanent or temporary support structures.

Core Advantages:High bending stiffness and excellent hammering toughness, capable of meeting ultra-long designed pile lengths through on-site splicing; fast construction speed, low soil displacement rate, no concrete curing waiting period, and temporary piles can be fully recovered and reused.

Global Compliance:Strictly meets mainstream international standards including European standards (EN 1997 geotechnical design and EN 10248 steel sheet piles), American standards (ASTM A572/A690 pile materials and AASHTO LRFD Chapter 10 Foundations), and Australian standards (AS 2159 pile foundation design and construction and AS 5100 bridge foundations).

Service Guarantee:Provides full-process technical support from geotechnical parameter verification, pile drivability analysis (WEAP wave dynamics simulation), pile type optimization, welding process evaluation to on-site high-strain dynamic monitoring and static load testing.

Product Line: Bailey Truss Bridge | Rolled-Girder Bridge | Plate & Box Girder Bridge | Launch Slide-In Bridge | Temporary Diversion Bridge | Pedestrian Bridge

Authorized Standards: AASHTO LRFD 2020, EN 1993, AS 5100:2017, EN 1090 CE, AWS D1.5, ISO 9001

Core Advantages: Modular factory prefabrication | Fast on-site erection | Reusable & relocatable | Permanent / temporary dual use | Containerized export packaging | Zero traffic interruption

Product Positioning:Focused on lightweight steel pedestrian bridges for urban slow traffic systems, parks and scenic areas, school campuses, and river-crossing walkways, balancing safe passage with landscape aesthetics, offering both standardized and customized product solutions.

Core Advantages:Lightweight truss or plate beam structures combined with factory prefabrication allow on-site installation in just a few hours; the bridge deck integrates anti-slip, drainage, and lighting systems, achieving "finished at the factory, ready for use on site."

Global Compliance:Strictly meets mainstream international standards, including European standards (EN 1990 pedestrian load and EN 1993 steel bridge design), American standards (AASHTO LRFD pedestrian bridge sections and ADA accessibility regulations), and Australian standards (AS 5100 and DDA accessibility specifications).

Service Assurance:Provides one-stop technical support, from human-induced vibration comfort calculations, anti-slip grade selection, accessible ramp optimization, to on-site hoisting solutions and nighttime construction traffic organization design.

Our Modular Steel Bridge delivers fast, durable, and cost-effective solutions for temporary and permanent crossings. Engineered for rapid assembly, it’s ideal for roads, railways, pedestrian paths, and emergency relief projects.

Product Positioning:Designed specifically for emergency rescue, military engineering, and infrastructure in remote areas, providing rapidly deployable, reusable steel bridge solutions covering temporary passages, post-disaster reconstruction, and permanent small-to-medium-span bridges.

Core Advantages:Standardized component design with fully bolted connections requires no on-site welding. A skilled team can complete the erection of a single span within hours; components are highly interchangeable, allowing for dismantling and reconstruction at different locations later, maximizing asset utilization.

Global Compliance:Strictly meets major international standards, including European standards (EN 1993 steel bridge design and EN 1090 manufacturing), American standards (AASHTO LRFD and AWS D1.5 welding), and Australian standards (AS 5100 bridge series and AS 1554 welding).

Service Assurance:Provides one-stop, full-cycle technical support, from load class selection, span configuration optimization, and transport packaging solutions to on-site assembly guidance and later dismantling and recycling.
