Galvanized Steel

The new continuous galvanized line with production capacity of 160,000 metric tons annually can produce coils and sheets ranged from 0.20 mm. to 1.20 mm. in thickness, 575 mm. to 1,255 mm. in width, and are produced conforming to TIS and JIS standards. With our commitment in quality, customers can be sure that every RSM galvanized sheet and coil has passed quality control testing on crack-proof forming which is an important quality in producing down stream products such as T-bar, purlin, air-condition insulation packing, and water tank, etc. Furthermore, our zero spangle products are mainly used in color coating applications which require special attention in appearance such as electrical and computer appliance. Because of these various type of application and long term commitment in quality, RSM products become one of the most accepted brand in the industry.Manufacturing Process The manufacturing process starts with cleaning dirt and oil film from the cold rolled strip surface. Then, the cold rolled strip will need to change its property from hard to soft iron for bending and forming purpose through annealing process.The temperature and atmosphere of the annealing furnace is strictly controlled in order to guarantee that every strip which passed this process will have quality according to the specific standards.For zinc coating process, the strip is passed through the zinc pot which the balance of compositions of alloys in the melting pot is closely monitored and the zinc coating mass is also strictly controlled by coating weight gauge. The coated strip, then, will go to the heat reducing process and the appearance controlling process.The appearance controlling process consists of minimized spangle and skin pass processes which are able to control the size and flatness of the spangle before passing through the tension leveler, the final adjustment of the flatness and physical properties.After the appearance controlling process, the requested galvanized sheets will be coated with chromate for the weather resistance. The strip which passed through all the processes will be stocked in coil or cut to length according to the inquiry of customers.GI Corrugated The cold-rolled coils are being imported from Japan and South Korea to the factories. The coils are processed with hot-dip galvanized coating system, a highly advanced technology from Japan. The company's products are also manufactured in conformity with TIS 50-2528 (JIS G3302-1991)
