China's push for high-quality development is increasingly being driven by private enterprises that combine technological breakthroughs with stronger connectivity across regions, playing a growing role in industrial upgrading and supply-chain resilience.

The trend comes as national efforts to upgrade industrial chains and strengthen the real economy continue to create new space for private manufacturers to move up the value chain.

In the manufacturing sector, Silvery Dragon Group Co Ltd Tianjin has expanded its footprint along the prestressed materials value chain, supplying core components for major infrastructure projects nationwide.

The company is currently the leading enterprise in China capable of providing an integrated solution covering prestressed materials, prestressed concrete components and equipment, as well as technical services, digital engineering, operation and maintenance monitoring, said Xie Zhifeng, chairman of Silvery Dragon Group.

Its self-developed ultra-high-strength prestressed steel strands, with tensile strength ranging from 2,100 to 2,400 megapascals, have been applied in large-scale highway and railway bridge projects, helping to improve structural load-bearing capacity and optimize engineering design.

According to Xie, the company has achieved full-process independent innovation across the prestressed materials chain — from process control in upstream wire rod smelting, to precision processing of prestressed products, and intelligent production of downstream concrete components.

Silvery Dragon Group has also taken part in the formulation and revision of dozens of national and industry standards. Among these, the successful development of the CRTS III high-speed railway track slab has not only broken technical monopolies, but has also become a key technological support for China's high-speed rail projects overseas.

Beyond traditional infrastructure, Silvery Dragon Group has expanded into the wind power sector in line with the country's dual-carbon goals. It has developed prestressing construction management and intelligent monitoring systems for hybrid wind power towers, enabling real-time monitoring, intelligent diagnostics and automated maintenance, and improving structural safety and durability.

"We will continue to invest in wind power and photovoltaic projects at home and abroad, advancing a green development strategy aimed at carbon neutrality in the real economy," Xie said.
