CANWIN BUILDING MATERIALS was founded in 2003 and reformed from the state-owned Zhejiang Lanxi Special Cement Company established in 1978. It is now a national company specializing in the research, development and industrialization of high molecular materials such as concrete durability enhancement materials (rust inhibitor series, preservative series), concrete temperature suppression materials (hydration heat inhibitor), ultra-fine grouting materials, and moisture-regulating boards The enterprise that has won the Science and Technology Progress Award has participated in the construction of many provincial and national key projects as well as foreign aid projects of the Ministry of Commerce. Such as the renovation project of the Afiniam Dam in Senegal, the Ningbo-Zhoushan Railway in Zhejiang Province, the second phase of the Ningbo-Zhoushan Expressway in Zhejiang Province, the newly-built Qiantang River Bridge in Hangzhou, Zhejiang Province, the Zhoushan-Daishan Cross-sea Bridge of Ningbo-Zhoushan Port in Zhejiang Province, the Yushan Bridge and the Fuchimen Bridge, the Xiushan Bridge in Zhoushan, Zhejiang Province, the Guanshan Bridge in Zhoushan, Zhejiang Province, the Shenjiamen Guanyin Cross-sea Bridge in Zhoushan, Zhejiang Province, the Beikou Bridge of the Oujiang River in Wenzhou, Zhejiang Province, and the Oujiang River Estuary in Wenzhou, Zhejiang Province The underground utility tunnel, Fuzhou Second Airport Expressway, Jiangsu Dafeng Port Railway, Qingdao Jiaozhou Bay Second Undersea Tunnel, Qingdao Jiaozhou Bay Undersea Tunnel, Gaoligong Mountain Tunnel of Yunnan Dali-Ruili Railway, Xiamen Second West Channel, Zhanjiang State Reserve Project, Guangzhou Gaode Land Corridor Project, Guangxi Fangchenggang Shuangdun Fishing Port Project and other engineering projects The company is equipped with advanced domestic ultrafine powder system production lines and polymer material (sheet) production lines, as well as advanced testing instruments, which ensure a 100% product qualification rate. The company's annual production capacity is 100,000 tons.

The company's production base has created a modern, garden-style R & D and production base that is one of the best in the industry. The white and gray modern curtain wall building in the factory is dazzling, the road is spacious and straight, and the grass is green. The flowers and trees are full of vitality, and the garden ornaments are scattered.

CANWIN leads the industry trend and is the first to implement green and clean production. Among them, the polymer materials sector company has designed the highest-level digital intelligent production line in the industry, achieving full-process digital intelligent control and full-process monitoring of reaction temperature, reducing human operation errors and ensuring product quality. The production of the product adopts leading-level production technology, and the traditional heating method is replaced by an electric heating control device. The entire process of material mixing and reaction takes place in a closed pipeline. Raw materials and finished products are transported by professional tank trucks to achieve zero emissions. Clean production has reached the international advanced level.

In 2008, the company's concrete durability project won the second prize of the National Science and Technology Progress Award. The core product, rust inhibitor, has been recognized as a "High-tech Product", and the company was awarded the title of "High-tech Enterprise of Zhejiang Province" as early as 2005. It has been awarded the title of "Contract-abiding and Creditworthy AA-level Unit" and "AAA-level Credit Enterprise". The company has successfully passed the quality, environment and safety management system certification. In addition, the company has also collaborated with renowned research institutions and universities such as Zhejiang University, Beijing University of Technology, and China Academy of Building Research, and has been approved to establish a "Provincial Technology Research Center". In 2016, the concrete anti-corrosion and rust inhibitor products reached the international leading level. In 2024, the company's concrete anti-corrosion project won the First prize for Scientific Progress of the Chinese Society for Corrosion and Protection.

As a leader in materials for enhancing the durability of concrete, CANWIN focuses on developing green and environmentally friendly special materials and is committed to promoting the industrialization of product applications. Adhering to the core culture of creating value through quality and building the future with strength, we take honesty as the foundation, forge our business with science and technology, lead the industry and benefit society.
