The siphon phenomenon is a natural phenomenon in fluid mechanics. It utilizes the weight and pressure difference of the liquid itself to easily draw the liquid from a high place to a low place without the aid of an external pump. Canlon's siphon roof drainage system relies on Bernoulli's fluid dynamics equations and is equipped with self-developed hydraulic calculation software to accurately match pipe diameter and number of ducts, ensuring stable siphon activation during extreme rainfall and forming full pipe flow. This is different from traditional gravity semi-pipe drainage and achieves rapid drainage.
In high-end industrial sectors such as new energy, precision manufacturing, and biopharmaceuticals, buildings are no longer mere shelters from wind and rain. A lithium battery plant workshop must strictly maintain temperatures below 25°C and humidity below 30%; otherwise, battery performance and yield rates are directly affected. If air quality fluctuates in a semiconductor cleanroom, the entire production line may face shutdown. In such scenarios, the roofing system is no longer just a waterproofing layer, but a "Super Shield" that safeguards production safety, product quality, and operational efficiency. Polymer waterproofing membranes represented by TPO, with their comprehensive properties of weatherability, energy-saving high reflectivity, chemical corrosion resistance, and wind uplift resistance, are becoming the preferred choice for high-end industrial plant roofing projects.
The Phase II Expansion Project of Asia Pulp & Paper (Shandong) Co., Ltd., for its household paper products, is located in Rizhao Economic Development Zone. It is a key industrial expansion project of the province and city, with a total investment of RMB 1.2 billion and a total construction area of approximately 92,000 square meters. The project mainly involves the construction of a new paper-making plant, a deep processing workshop, an intelligent automated warehouse, and supporting public and environmental protection facilities. It will also build six new high-end household paper production lines. After completion, the company's total household paper production capacity will reach 300,000 tons/year, with an annual increase in output value of over RMB 2.2 billion. This will further strengthen the regional pulp and paper industry cluster and bring significant economic and social benefits.
In recent years, China has been actively promoting the construction of new infrastructure, new energy and new industries in countries along the "Belt and Road". It has used "Chinese strength" to empower the infrastructure construction of Southeast Asia, Central Asia and even African countries. The export of building materials has become a major market hotspot. Canlon has also gone abroad through a "combination punch" of general trade and foreign aid projects, exporting "international quality at Chinese prices" and winning market share and reputation in foreign lands. Today, Canlon presents the latest "combined edition" of overseas projects.
On January 27, 2026, the signing ceremony of the annual strategic agreement between Canlon and Central Asia Canlon (CCA) was successfully held in the Polymer Industrial Park, marking the official start of a new cycle of cooperation between the two parties and further enhancing Canlon's brand influence in Central Asia. In the future, Canlon Group will continue to uphold the spirit of innovation, cultivate the Central Asian market, and make the brand influence of "International Canlon" stronger and stronger, contributing more "Canlon power" to the global waterproofing industry!
On January 16, the No. 1 nuclear island of the Jiangsu Xuwei Nuclear Power Plant in Lianyungang began concrete pouring, marking the start of the main construction phase and initiating my country's transformation of nuclear energy from primarily power generation to diversified supply. The project utilized multiple waterproofing materials from Canlon to construct a robust and reliable waterproofing system. As the first nuclear power unit to commence construction in China at the start of the 15th Five-Year Plan period, the Xuwei project primarily focuses on industrial heating while also generating electricity, with a total investment exceeding 72 billion yuan.
Recently, Canlon roof siphon rainwater drainage system, with its green and low-carbon attributes and superior performance, empowered a key project—the heavy chemical equipment production base construction project of Yongda Chemical Machinery (Rudong) Co., Ltd. Canlon Roof Siphon Rainwater Drainage System was applied to the roofs of the combined plant and special materials plant in this project. The Canlon technical team participated throughout the process, carried out secondary design refinement of the drawings, supplied materials, and provided on-site construction and installation technical guidance.
The Fengcheng Lidu project is located at No. 68 Fengxiang Avenue, Qingcheng District, Qingyuan City. Developed by Qingyuan Hengyuan Zhaoye Real Estate Development Co., Ltd., the project primarily consists of high-rise residential buildings, supplemented by apartments, villas, and commercial spaces. The surrounding area boasts abundant educational, medical, and commercial resources. The total land area is approximately 230,000 square meters, with a total construction area of approximately 700,000 square meters. The project's green roof drainage system utilizes the Canlon SDR siphon drainage collection system, with on-site construction handled by Canlon's Qingyuan partner, Guangdong Yuhao Housing Repair Co., Ltd.
On November 5, 2025, the 2025 China International Roofing and Waterproofing Technology Exhibition was grandly held at the Shanghai New International Expo Centre. Under the theme of "Good Houses, Good Waterproofing, Good Future", Canlon made its debut with the theme of "Integration Leading New Quality Empowerment", presenting a feast of comprehensive building waterproofing system solutions with polymer as the core technology to professional audiences at home and abroad. At this exhibition, Canlon was located at booth 201 in Hall N1, attracting keen attention from experts and industry colleagues from home and abroad.
