Recommended series: Lesso PVC solid wall drainage pipe, Lesso PVC electrical casing
 
Liansu is a leading enterprise in the plastic pipe industry, with the largest domestic sales volume in the field of plastic pipes, and the company's revenue scale reached more than 20 billion yuan in 2017.
 
Lesso can be regarded as the earliest domestic production of PVC products enterprises, in 1993 with PVC wire sheath pipe to establish a market position, today, PVC pipe manufacturing is still the star business of Lesso, sales in 2017 reached 1.58 million tons, sales revenue of more than 10 billion, accounting for 58% of Lesso's revenue in 2017, far more than Rifeng, Weixing and other brands.
 
In recent years, Lesso has also begun to implement a diversification strategy, the acquisition of a number of home building materials enterprises, involving plumbing and bathroom, doors and windows, decorative plates and other fields, at present, Lesso has more than 10,000 product categories, to achieve full coverage of building materials products, but its largest business is plastic pipes, accounting for 88.9% of revenue, in contrast, other products are currently only a foil.
 
Similar to many large Chinese enterprises, Lesso has invested a lot in internationalization, and in developed cities such as New York and Sydney, Lesso has launched a global O2O sales platform - Lingshang Global Home, which opens up the consumer market through the sale of high-quality building materials; In Southeast Asia, Africa and other places, Lesso has directly taken root in the local area through mergers and acquisitions of local factories and contracted project construction. As it has just begun its overseas expansion, Lesso's overseas revenue currently accounts for only 3%, but it is developing very rapidly, with an annual revenue growth rate of more than 30%.
 
Lesso has 26 production bases around the world, the largest among domestic pipeline enterprises, and its production strength is very strong. In addition to self-produced products, Lesso also accepts OEM business, and part of the well-known Siemens sockets in the market are commissioned by Lesso to produce Siemens' star products, which is enough to confirm the manufacturing strength and reliability of Lesso.
 
Liansu has a wide range of products, water supply pipes, drainage pipes, home improvement electrical pipes, engineering grade electrical pipes are produced, the material is PVC-U, which is the most commonly used material for PVC pipes, compared with early PVC, PVC-U has higher strength and stronger corrosion resistance, but under higher temperature conditions, PVC-U pipes will have monomers and additives seeping out, so if used in water supply systems, the water temperature should not be higher than 45 °C.
 
Lesso PVC-U water supply pipe has superior workmanship, smooth inner wall of the pipe, its roughness coefficient is only 0.009, low fluid resistance, smoother water conservancy transmission, and 25mm diameter pipe is 3.77 yuan per meter, the price is relatively cheap. Liansu PVC drainage pipe is divided into solid wall pipe, hollow wall pipe, spiral pipe, hollow wall spiral pipe, at present, home decoration mainly uses solid wall drainage pipe, the price is 8 yuan per meter, hollow wall and inner spiral pipe noise reduction ability is stronger, the price is slightly more expensive than solid wall pipe, commonly used in the main drainage pipe or engineering project of the building.
 
Liansu PVC electrical casing is divided into red and blue colors, red represents strong electricity, blue represents weak electricity, which is convenient for separating strong and weak wires during decoration and avoiding electric shock and strong and weak electric interference. At the same time, its insulation is excellent, it can withstand 25 thousand volt voltage without being broken down, and the safety is extremely strong, and the price is 2.86 yuan per meter. According to the report of the National Engineering Composite Materials Product Quality Inspection Center, its impact resistance is far better than the industry standard, and it is a high-quality engineering-grade PVC electrical casing.
