The prestressed high-strength concrete piles of Sanhe have a wide range of adaptability, complete varieties and specifications; high bearing capacity, good impact resistance and bending resistance, and strong adaptability to geological structures; convenient transportation and lifting of piles; The construction site is clean and civilized, does not pollute the environment, and meets environmental protection requirements; it is an energy-saving and environmentally friendly green building material with reliable pile quality, convenient inspection and low supervision intensity. It is widely used in industrial and civil construction, highways, railways, ports, water conservancy and other projects. In order to meet the needs of the market, Sanhe also developed high-strength anti-corrosion and durable prestress technology and put it into the production of piles, which can be applied to the freezing and thawing environment in northern areas, the chloride corrosion environment in coastal areas, and the inland sulfate corrosion environment. Such as areas with high durability requirements.

 Project key performance indicators/technical parameters (take PHC500 AB 125-10 pipe pile as an example):

       1. The thickness of the concrete protective layer>40mm;

       2. When loaded to 136KN*m of anti-cracking moment, no cracks appear on the pile body;

       3. When loaded to the ultimate bending moment of 226KN*m, the pipe pile does not appear in any of the following situations:

       a. The width of concrete cracks in the tension zone reaches 1.5mm;

       b. The tension bar is broken;

       c. Concrete damage in compression zone;

       4. The concrete strength grade is not lower than C80.

In recent years, Sanhe piles have continued to introduce new ones, and have successively developed corrosion-resistant piles (DPHC piles), large diameter piles (φ800 and above), mixed-reinforced prestressed concrete piles (PRC piles), pencil piles, and variable diameter piles. New products such as piles, prestressed concrete solid square piles and prestressed concrete hollow square piles, and new prefabricated products such as PCS piles for foundation pits and river courses (PCS piles) and prefabricated walls have been developed, which greatly broadens the variety of products meets the diverse needs of customers in the market.

Guangdong Sanhe Building Materials Group Co., Ltd. was founded in 1993 and has developed into a modern large-scale prestressed high-strength concrete piles production and group operation enterprise integrating R&D, design, production, sales and service. Sanhe is one of the largest manufacturers of prestressed high-strength concrete piles in China. It has set up production bases in Guangdong, Fujian, Jiangsu, Hunan, Hubei, Shandong, Shanxi, Liaoning, Anhui, Heilongjiang and other places, with nearly 50 advanced production line has formed an annual production capacity of 70 million linear meters of piles. The production and sales scale and market share of "Sanhe" piles in coastal and riverside cities are among the best in the piles industry. While continuously satisfying the growing domestic market demand, Sanhe focuses on the development and utilization of resources in the international market, and its products are now sold to Vietnam, Hong Kong, Macau, Taiwan etc. 

In the future, Sanhe will complete the effective integration of various corporate operating elements, and develop towards high-tech, high-performance, and high-quality products; and production technology towards low energy consumption, low material consumption, and high automation. Control the development of the horizontal direction; and actively explore the international market, expand export business, enhance the international competitiveness of enterprise products, and carry out comprehensive integration of the product market. 

The international development strategy of Sanhe is divided into two phases: the first phase takes trade as the forerunner, through sales and trade, increases the visibility and market share of Sanhe products in overseas markets, and cultivates customer groups; at the same time, in-depth research on various countries of the market prepares for the establishment of production bases for overseas investment; in the second phase, overseas investment is made at a time and place to establish production bases.

At the 2020 China Concrete Exhibition, the main contents of Sanhe are pre-stressed high-strength concrete corrosion-resistant pile (DPHC pile), pre-stressed large-diameter concrete pile (ϕ700-ϕ800), and pre-stressed concrete hollow support pile (PCS pile), prestressed concrete solid square pile, prestressed concrete hollow square pile, mixed reinforced prestressed concrete pile, concrete pile, tip integrated pile, variable diameter pile, prestressed centrifugal assembled fence and other technologies and products application situation. Among them, DPHC piles have been successfully applied to the Hong Kong-Zhuhai-Macao Bridge Project and the Zhuhai Hengqin Port Project, which has increased the service life of the building foundation and produced better economic benefits. Various types of pile products of Sanhe have been applied in a wide range of projects and gained a good reputation among users.
