On March 15, 2025, Hegang Steel officially launched its S550GD+Z high-strength galvanized steel sheet in Urumqi, designed for extreme environments. This product utilizes a niobium-titanium microalloyed substrate and ZM Ecoprotect® coating technology, achieving a yield strength of 550-800 MPa (twice that of conventional galvanized steel sheet) and salt spray corrosion resistance exceeding 1,000 hours (ISO 9227 certified). In field tests at the Bukhara photovoltaic power station in Uzbekistan, its textured embossed surface increased the wind load resistance of the support to 35 m/s and improved the installation friction coefficient by 40%. This material has been used in 23 photovoltaic and logistics warehousing projects in Central Asia, with a monthly production capacity of 12,000 tons.

The Hebei Iron and Steel Technology Research Institute today released its "316L Stainless Steel Pipe Energy Application Guide," revealing three innovative technologies: 1) ultra-low temperature toughness treatment, achieving an impact energy of ≥100J at -196°C; 2) electrolytic polishing of the inner surface to Ra ≤ 0.4μm, reducing crude oil adhesion by 35%; and 3) a laser QR code traceability system. This material has successfully served the Caspian Sea oil fields in Kazakhstan (resistant to H₂S corrosion), the Russian Arctic LNG project (at -50°C), and the Central Asia hydrogen pipeline pilot project, with annual pipe exports exceeding 8,000 tons.

To withstand the high temperatures and strong UV rays of the Middle East, Hegang Steel's PVDF color-coated steel coils achieve a technological breakthrough with a four-layer protection system: epoxy primer (5μm) + fluorocarbon topcoat (20μm) + nano-titanium dioxide barrier layer, resulting in UV resistance of up to 3,000 hours (ΔE ≤ 2). Field testing in Dubai has shown that its 115° hydrophobic surface reduces building energy consumption by 30%, and its resistance to 10% hydrochloric acid exceeds industry standards. By 2025, 50,000 tons of custom color-coated steel coils had been delivered to the UAE, with a color difference control accuracy of ΔE ≤ 0.5.

In a recent interview, Zhang Gong, Technical Director of Hegang Steel, stated:
For high-salt and alkaline photovoltaic mounting systems: We recommend a dual-coating solution of S550GD+Z+AZ150. A 120μm galvanized layer triples the lifespan.
For extremely cold weather pipelines: Ceq ≤ 0.42%, 316L molybdenum content ≥ 2.8%, and -50°C impact energy ≥ 80J are required.
For Middle Eastern architectural color coatings: A PVDF resin content ≥ 70% is key, combined with a 2000-rpm sand-resistant coating (the national standard is 500 rpm) to achieve a 15-year warranty.

On May 20, 2025, Hegang Steel's S550GD+Z galvanized steel sheet received TÜV Rheinland certification for photovoltaic support materials, becoming the first steel company in Central Asia to achieve this certification. Certification data shows: impact energy ≥ 27J at -40°C (20% higher than the IEC standard), red rust area <1% after 120 cycles of CCT testing, and ultimate load of the support structure 6.5kN/m². This certification will accelerate the implementation of photovoltaic projects in Kazakhstan and Uzbekistan, with exports expected to increase by 200% by 2025.
