The company was founded in 2002. For more than 20 years, it has been deeply engaged in the research and development, production, and service of core components of construction machinery, focusing on the meticulous craftsmanship and technological innovation of core sealing accessories for shield machines. It is a highly capable professional solution provider of shield tail sealing brushes in China.

The company's core flagship product is the shield machine tail sealing brush. As a core safety accessory for shield machine tunneling construction, the product can adapt to various complex geological construction environments, effectively ensuring the safety, stability, and efficiency of tunnel excavation operations. It is a key "safety guardian" for shield construction in infrastructure projects. Relying on in-depth insights into various construction scenarios, we fully understand the differentiated needs of each engineering project. We abandon the limitations of standardized mass production and focus on providing one-to-one customized solutions. According to the customer's shield machine model, construction geological conditions, project working conditions, and other core requirements, we can specifically optimize the wear resistance, pressure resistance, and sealing reliability of the products, precisely matching the strict standards of various tunnel constructions, and building a solid safety barrier for project construction.

With solid product quality and a professional service system, the company's products have a wide range of application scenarios, fully covering various infrastructure fields such as urban subways, railway and highway tunnels, cross-sea and cross-river tunnels, municipal utility corridors, and water conservancy projects. The market layout is based nationwide and radiates globally. Customers are spread across major cities in China, and products are exported to overseas regions such as the Americas, Europe, Southeast Asia, and the Middle East. We have long established long-term, stable, and mutually beneficial strategic cooperative relationships with major large construction groups and well-known shield machine manufacturers, with a deep industry reputation.
