Galvanized Roller Shutter Door
Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.
Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.

The second seminar of “Hegong Large Belt Abrasive Testing Machine Program†was held
On the afternoon of November 9, the second seminar of the “Hegongda abrasive belt grinding test machine program†organized by the coated abrasives branch was held at the School of Materials Science and Engineering of Henan University of Technology. Wang Mingyuan, Secretary General of the Coating Abrasives Branch, Professor Zou Wenjun, Dean of the School of Materials Science and Engineering, Henan University of Technology, Zhang Changwu, Dai Hongjun, members of the coated abrasives expert committee, and other representatives of the belt industry attended the meeting. The participating experts carefully listened to the idea of ​​the belt grinding test mechanism detailed by the professor Cui Wei of Henan University of Technology and put forward some new ideas. Wang Mingyuan, Secretary General of the Coated Abrasives Branch, thanked the teachers and experts of Henan University of Technology for their work on the development of the “sand belt grinding test machine programâ€. Through the joint arguments of many experts, the prototype of the abrasive belt grinding test machine has been initially formed, which is a great improvement from the previous one. It is believed that with the joint efforts of many experts, the belt grinding test machine will become a set of equipment that is excellent in production and processing, reliable in measurement data and efficient in work efficiency. The delegates expressed their admiration for the project's efficiency by absorbing the reasonable suggestions put forward by everyone in a short period of 20 days and taking out the improved efficiency of the “sand belt grinding test machine programâ€. Completion is also full of confidence. Professor Zou Wenjun, Dean of the School of Materials, Henan University of Technology, expressed his gratitude to the experts for their supplementary comments on the improvement of the abrasive belt grinding test machine mentioned in the repeated argumentation. Dean Zou said that we will sort out some suggestions put forward by everyone, and make adjustments again to ensure that the belt grinding test machine program can be put into operation as soon as possible. Subsequently, President Zou invited Wang Mingyuan, Secretary General of the Coating Abrasives Association, and a number of experts to visit the Superhard Materials Performance Testing Laboratory, PCVD Laboratory, Hardness Testing Laboratory, and Abrasive Performance Testing Laboratory of the School of Materials. The Engineering Technology Center specializing in the specialty of Materials College.
