Concerned about the Growth of Quality, Connotation of Development and Promotion of Regional Cooperation

Known as the "Davos Forum" of the three provinces' chlor-alkali industry, the 2011 Lu Suyu Chlor-Alkali Enterprise Development and Cooperation Forum closed on September 17 in Kaifeng City. The conference closely linked the theme of “Chlorine's downstream industrial chain and differentiated development” and interacted and exchanged the latest developments of chlor-alkali enterprises in the three provinces, and discussed the cooperation direction and model of chlor-alkali enterprises, chemical parks, and industrial clusters in the three provinces, and discussed the development of regional cooperation. Reached five points of consensus.


According to statistics from the China Chlor-Alkali Industry Association, the production capacity of caustic soda in Shandong, Jiangsu, and Henan provinces currently accounts for more than one-third of the country's total. Shandong Province is the country's leading chlor-alkali industry. At present, caustic soda production capacity and output account for more than a quarter of the country's total; Jiangsu Province is the province with the best overall development of chlorine products, the most comprehensive industrial park, and the best chlor-alkali benefit; Henan Province relies on The resources and market advantages have gradually become the rising star of the chlor-alkali industry. Especially after the province's coal integration, large coal companies are involved in the salt chemical industry, and the development momentum is rapid.


In order to promote the sound and rapid development of the industry, the chlor-alkali enterprises in the three provinces came together to enhance mutual understanding and integration. After in-depth exchanges and substantive discussions, chloro-alkali enterprises in the three provinces reached a five-point consensus in the future common development direction: First, focus on the development quality, reasonably regulate the total amount of caustic soda, polyvinyl chloride, soda ash and other bulk products, and eliminate backward production capacity with superior production capacity. And technology, increase energy-saving emission reduction efforts. The second is to encourage and promote mergers and acquisitions, strong alliances, increase industrial concentration, and avoid disorderly competition. The third is to encourage and accelerate the development of salt chemical industry agglomeration and park development. The three provinces learn from each other's experiences, accelerate the adjustment of product structure, pay attention to differentiation, and vigorously develop downstream high value-added products based on the actual and core advantages of their respective companies. The resource-pull type economy changes to the technology. The fourth is to strengthen key and cutting-edge technology research, accelerate the promotion and application of new energy-saving technologies and processes, establish circular economy models in different regions, reduce consumption and costs, and enhance competitiveness. Fifth, develop and apply clean production and environmental protection technologies. During the “Twelfth Five-Year Plan” period, we must promote the low-mercury and non-mercury processes of PVC production, focus on the research and development of low-mercury catalysts, and popularize the use of low-mercury catalysts by 2015.


Zhang Wenlei, Secretary-General of China Chlor-Alkali Industry Association, and representatives from three provinces of enterprises jointly discussed the current situation and development direction of China's chlor-alkali industry. The forum also invited experts in chlor-alkali, fluorine, and silicon industries such as the Institute of Petroleum and Chemical Industry Planning and the China Bluestar Chemical Group Chenguang Chemical Research Institute to exchange ideas on issues such as the development of chlor-alkali downstream industries. Experts from the technology, market, and development prospects From multiple perspectives to help companies make decisions. During the forum, the chlor-alkali enterprises in the three provinces actively sought cooperation opportunities and had reached some cooperation intentions in the market, capital, and technology.

A Trapezoidal Sheet Roll Forming Machine is a regular metal sheet roll former that produces metal roofing sheets or roof panels for both individual and industrial building.

Trapezoidal roofing sheets are the most popular metal roof panels not only for residential buildings but also for commercial or industrial buildings. There are so many different profiles for a variety of applications. People like to use low-profile trapezoidal sheets for elevation and IDT roofing, while for wide-span roofing and load-bearing structures, they tend to select high-profile trapezoidal sheets. In addition,  trapezoidal sheets have other names in Africa as industrial trough IT4, IT5, IT6 roof profiles, therefore people can barely find two exactly the same trapezoidal sheet Roll Forming Machine in the markets.

Brief introduction of Trapezoidal Roof Sheet Roll Forming Machine:

66TR750 Trapezoidal Sheet Roll Forming Machine

This trapezoidal sheet roll forming machine produces trapezoidal sheets from colour ppgi, gi, aluzinc sheets, and sometimes aluminium steel coils (aluminum roof panels are prefered in Nigeria). Generally, material thickness varies from 0.3 to 0.8mm, and width varies from 914mm to 1250mm. However, in some applications, material thickness can reach up to 1.5mm, like roof deck. Furthermore, in some countries or areas, people use G550 material to make full hard metal roofing sheets.

Sometimes when a client needs to produce trapezoidal sheets with different effective widths with anything else remained the same. In this case, the investment shall be made on only one machine, because a trapezoidal Roof Panel Roll Forming Machine is always adjustable for different feeding widths. This means you can make trapezoidal roof panels with different effective widths from different-width materials. However, a client must need two trapezoidal sheet roll forming machines for manufacturing two panels at the same time.

Just like the regular roof sheet roll former, a trapezoidal sheet roll forming machine typically consists the components as following:

  • Manual Decoiler
  • Entry/feeding Guide
  • Roll Forming Unit
  • Hydraulic Unit
  • Cutting Unit
  • Control system
  • Runout Tables

There are different names for trapezoidal sheet roll forming machines in some regions or areas!  For example, in Africa, people like to metra roll forming machine, and sometime they give the name industrial trough IT4, IT5, IT6 roof sheet roll forming machineetc.

MAXON designs and builds customized trapezoidal sheet roll forming machines. For instance, some customers ask for G550 metal roofing sheet roll forming machine, some customers may prefer a separate forming stands structure trapezoidal sheet roll forming machine, or some customers may need safety guard on the roll forming machine body etc.
