OUR ADVANCED PRODUCTION CAPABILITIES
COUPLED WITH OUR RELENTLESS PURSUIT OF ENGINEERING EXCELLENCE
Enable us to deliver durable, precision-engineered steel components that drive efficiency, sustainability, and success for our esteemed customers across the globe.
The main structure of the sea-crossing bridge is constructed using high-strength H-beams and corrugated steel plates, such as the bridge project at Shanghai Dishui Lake Island. Corrosion-resistant coatings ensure a 50-year service life, and the seismic resistance level exceeds Grade 8, suitable for urban elevated expressways and cross-river bridges.
Customized weather-resistant steel plates and square tubes are used to produce container frames, such as the 40-foot standard containers exported to Southeast Asia. Salt spray testing verifies corrosion resistance, stacking strength meets international maritime standards, and the sealing strip design ensures safe cargo transportation.
Channel steel and angle steel combinations are provided to achieve modular steel structure buildings, such as the prefabricated steel structure modules used in the Kunshan Elysée Royal Villa area. On-site assembly time is reduced to 1/3 of the traditional construction cycle, achieving green building certification standards.
A full range of building materials, from rebar to steel gratings, is supplied, covering the entire construction cycle of the Shanghai Chongming CITIC Nursing Home project. BIM technology is used to achieve precise material proportioning, ensuring zero errors in concrete pouring and steel structure connections, and the project received a provincial-level high-quality engineering award.
Specialized round steel is used to produce high-speed railway track accessories, such as the dedicated fastening system for the Beijing-Shanghai High-Speed Railway line. High-precision cold rolling technology ensures track smoothness of ≤1mm/10m, meeting the requirements for 350km/h high-speed train operation, and improving fatigue resistance by 40% for heavy-duty freight lines.
Galvanized angle steel and steel pipe towers are used to customize transmission tower structures, such as the East China Power Grid 500kV transmission project. A wind resistance design coefficient of 1.3 is adopted, and finite element analysis verifies seismic performance, ensuring zero power transmission interruptions during typhoon seasons. The tower body has a corrosion-resistant lifespan of 30 years.
