Laying the Foundation, Embarking on the Journey
Anhui Dingzhu Technology Group (formerly Hefei Dingzhu Trading Co., Ltd.) was officially established in Hefei Huishang Building Materials City. In its early stages, the company focused on steel trading and basic engineering construction. Guided by the philosophy of "Quality First, Integrity-Driven Operations," it quickly earned trust from local clients. The successful completion of its first major project, "Steel Structure Supply for Hefei Huishang Tower," solidified the company’s reputation. The same year, a professional sales and technical team was formed, establishing a dual business model of "Trade + Engineering Services" and injecting momentum for future growth.
Strategic Upgrade, Dual-Engine Growth
To overcome business limitations, the company relocated to East China Building Materials City in Longtang, Feidong, expanding its office and warehouse space to 3,000 square meters. The "Manufacturing Transformation Plan" was launched, with investments in its first steel structure production line, introducing CNC cutting machines and welding robots. This marked the shift from pure trading to a "Trade + Manufacturing" model. A strategic partnership with China Construction First Group (CSCEC) was secured, supplying steel support systems for Hefei Metro Line 2—a milestone entry into the rail transit sector. Through optimized supply chains and cost control, annual revenue surged by 120%, propelling the company into the top three regional industry players.
Smart Manufacturing, Nationwide Expansion
The group headquarters moved to No. 1 Jinshan North Road, Bantang Economic Development Zone, Chaohu City. Concurrently, two intelligent production bases in Jiaxing and Dingyuan commenced operations. With a 50-million-yuan investment in advanced equipment like 25,000-watt laser cutting machines and heavy-duty plate rolling machines, the company achieved full-process digital management (production-inspection-logistics), boosting annual capacity to 50,000 tons. Product lines expanded to high-end sectors such as shield machine components and metro lattice columns. A landmark project, the Suzhou Jinji Lake Science and Technology Innovation Center’s super high-rise steel structure, was secured, extending services across the Yangtze River Delta. The same year, it was recognized as an "Anhui Provincial Specialized and Sophisticated SME," with its R&D team growing to 30 members.
Innovation Leadership, Accolades Achieved
Awarded the title of "National High-Tech Enterprise," with 12 national patents granted for shield machine component technologies. The "Adaptive Tunnel Sealing Device" filled a domestic technological gap. ISO9001 Quality Management System Certification was obtained, achieving a 99.8% product qualification rate. Partnering with China Metallurgical Group (MCC), the "Smart Construction Joint Lab" developed next-generation prefabricated steel support systems for Hangzhou Asian Games venues. Annual R&D investment surpassed 10 million yuan, with technology-driven revenue contributing 35% to total profits, cementing the company’s position as an industry innovation leader.
