Leading the next generation of structural steel technology to maximize yield ratios, minimize weight, and transition toward sustainable steelmaking processes.
Developing structural steel with micro-alloying elements (Ti, Nb, V) to optimize mechanical properties, yielding superior load performance while reducing overall frame dead-weight.
Transitioning from standard hot-dip galvanization to Zn-Al-Mg (Zinc-Aluminum-Magnesium) coatings that offer up to 4 times the corrosion resistance of traditional galvanized layers in aggressive halide environments.
Aligning with global carbon neutrality benchmarks by integrating Electric Arc Furnace (EAF) technologies and utilizing premium scrap metal inputs to achieve significant embodied carbon reduction.
Engineered structural steel designed to meet rigorous stress profiles across various critical industrial vertical segments.
For high-rise office frameworks, structural bridge systems, and large-scale industrial warehouses. Our hot-rolled and cold-formed structural steel coils provide precise, reliable modulus of elasticity and yield strength ratings (e.g., S355JR, ASTM A36) to guarantee structural safety under dynamic and static wind loads.
Supporting wind turbine tower sectors, photovoltaic frame mounts, and long-range high-voltage electrical pylons. Outdoor structural assemblies require premium coatings to mitigate oxidation over multi-decade lifecycles.
Combining automated production lines with smart logistical networks to provide reliable structural steel delivery schedules.
Our hot and cold rolling systems feature continuous gauge monitoring, providing consistent coil flatness, reduced mechanical anisotropy, and precise thickness control.
Every production run undergoes non-destructive ultrasonic testing, tensile and yield evaluations, and spectral analysis to verify metallurgical grade compliance prior to shipment.
Located near the Port of Ningbo, our facility utilizes deep-water maritime routes to optimize international transit schedules, reduce freight costs, and minimize cargo handling hazards.

Providing the documentation, traceability, and mechanical performance verification required by international procurement departments.
Navigating international steel trade demands absolute compliance with cross-border frameworks. The procurement team at Ningbo Puppet Steel ensures each order conforms to the necessary regional benchmarks, such as ASTM (USA), EN (Europe), JIS (Japan), and GB/T (China). We supply complete Mill Test Certificates (MTC) matching EN 10204 3.1 or 3.2 formats, providing full chemical composition breakdowns, heat numbers, and mechanical property testing values.
Additionally, we work closely with top-tier inspection organizations (including SGS, Bureau Veritas, and TÜV SÜD) to execute pre-shipment quality audits. From raw substrate inspection through cold rolling reduction rates, hot-dip coating bath dwell-times, and post-treatment passivation, we provide complete, transparent process validation. This mitigates supply risk and ensures seamless integration with downstream fabrication projects.
Navigating global customs, anti-dumping policies, and regulatory compliance to ensure reliable, worry-free international shipments.
We help structural importers optimize logistics routing, verify product classifications, and leverage compliant tariff structures to help minimize additional import duties.
Our production facilities comply with ISO 14001:2015 standards, allowing partners to fulfill green building procurement benchmarks (such as LEED or BREEAM).
We support remote live-video testing, third-party quality evaluations, and technical consultations, ensuring clear alignment on engineering specifications.
