Come on, be friends with Innovation and See China, feel Chinese culture!It is a journey that provides a deep understanding of Chinese culture and its enduring legacy.



At present, China has the largest number of UNESCO Intangible cultural heritage related projects in the world.
Innovation pipeline believe these cultural stories with a long history are attractive enough to make Hainan friends interested in Chinese Cast iron expansion products.



Understanding Chinese culture begins here:

The Grand Canal, also known as the Beijing-Hangzhou Grand Canal, is one of China's greatest engineering achievements and has played a crucial role in China's history and culture. This ancient waterway spans over 1,700 kilometers and connects Beijing in the north with Hangzhou in the south, passing through Tianjin, Hebei, Shandong, Jiangsu, and Zhejiang provinces. Construction of the canal began in the 5th century BC and continued over the centuries, with major expansions occurring during the Sui and Tang dynasties. Today, the Grand Canal is a UNESCO World Heritage Site and remains an important waterway for transportation and irrigation.
One of the most remarkable features of the Grand Canal is its length. At over 1,700 kilometers, it is the longest man-made waterway in the world. This engineering marvel was created by connecting several existing rivers and canals, including the Huanghe (Yellow River), the Huaihe River, and the Yangtze River, to create a seamless network of waterways that allowed for easy transportation of goods and people throughout much of China.
For centuries, the canal served as a vital link between the northern and southern regions of China, and was used to transport goods such as rice, tea, and silk. It also facilitated the movement of troops and officials, enabling the central government to maintain control over its vast empire.

Build long-term relationships and grow organically.

The right balance of people, process and technology allows us to consistently exceed customer expectations in terms of quality, precision, speed and cost. Let's talk about your next project and how we can meet your specific requirements.

Innovation respect your privacy. Whether to cooperate is the result of your careful investigation, not the result of Innovation's efforts to communicate!
