Roval was founded in Osaka, Japan, in 1955. Shanghai Roval Zinc Rich Paint Corporation was established in China in 2003 and the Roval (Shanghai) Sales&Trading Corporation was established in 2007. For more than 60 years, we have been devoting ourselves to R&D, production and sales of " Roval " cold galvanizing compound. Roval coating with 96% zinc content in dry film has the same anti-rust effect as hot-dip galvanizing. It is widely used in the repair, renovation of galvanized parts and the replacement of hot-dip galvanizing for all-round coating of steel structures. The cooling tower of refrigeration equipment contains a large number of hot-dip galvanized steel parts, and these steel parts need to do a lot of welding during the production and installation process. Anti-rust treatment shall be carried out for these welding positions becused the original hot-dip galvanizing was damaged during welding. ROVAL, as the most famous hot-dip galvanizing repair brand in the industry, is widely applied on various repair parts of refrigeration equipment to provide reliable protection for the equipment.
