Recommended series: AD electrical casing, AD PVC drainage pipe
 
Gongyuan Pipeline is a brand of Yonggao Co., Ltd., which has won the "Top 500 Private Enterprises in China" and "Top 100 Most Growing Enterprises in China" for many times, presided over and participated in the formulation and revision of 24 national (industry) standards, and is one of the enterprises with the most product standards drafted in the plastic pipe industry.
 
Yonggao Co., Ltd. is a key high-tech enterprise of the National Torch Program, with a number of postdoctoral research workstations, national enterprise technology centers, and national laboratories, with engineering and technical personnel accounting for 10%, and 12 new invention patents in 2017 alone, with strong R&D strength.
 
In terms of business structure, AD and Liansu are very similar, although they involve photovoltaic solar energy, electrical switches and other fields, but the plastic building materials business revenue still accounts for 95% of the revenue, of which PVC pipe revenue accounts for half, which is the company's most important business. The high proportion of PVC business is mainly related to market demand, PVC pipe is cheap, water, electricity and gas can be used, the market demand is the largest, and it is the most commonly used type of pipe, accounting for more than half of the total output of plastic pipes.
 
However, compared with Liansu and Zhongcai, the product sales market of AD Pipeline is relatively narrow, mainly concentrated in East China, accounting for 62% of the total revenue, and the regionality is relatively strong. In order to improve this situation, AD has also established a marketing center in North China and a storage center in Xi'an and Guiyang, intending to penetrate into other regions, and the larger market investment has also diluted the profits of North China and Southwest China, with a gross profit margin of only about 15%, 10% lower than that in East China.
 
There are few consumer-grade PVC pipes under the company, only PVC-U drainage pipes and electrical casing, the drainage pipes have a relatively good silent performance, the materials are also very solid, the impact resistance is strong, and the price of 50mm diameter pipes is 8 yuan per meter. At the same time, AD provides floor drains and other drainage pipe fittings on the same floor, which is convenient for users who do drainage decoration on the same floor to purchase a complete set. Electrician casing has red and blue two-color and white models to choose from, home decoration is recommended to use red and blue, safer, and to avoid strong and weak electrical interference, the price is 1.93 yuan per meter, slightly lower than Zhongcai.
 
In addition to consumer-grade products, AD has more engineering pipes, such as PVC double-wall corrugated pipes for municipal projects, power PVC pipes, and noise-reducing PVC pipes for overall building drainage. Among them, the noise level of the AD PVC building drainage pipe is currently the lowest in China, the ventilation capacity of the pipeline system is also very good, the pressure fluctuation is small, and the drainage is smooth.
