The purpose of the Continuous Galvanizing Line (CGL) is to apply a coat of zinc onto the surface of steel sheets in an effort to increase their corrosion resistance. There is a wide range of control of zinc coat thickness, and the galvanized steel sheets are used for a broad range of purposes, including construction materials, automobiles and electrical appliances.To meet the growing demand of the market for zinc-aluminium coating, JJRS has developed and adapted its equipment to be able to produce Zn-Al coated strips under the best quality conditions for very different steel grades.

We support all types of coating kinds. Our proprietary air knife, enables high levels of precision in the control of zinc coating weight, covering a wide range of zinc coating, from low-speed thick coating to high-speed thin coating. It effectively inhibits zinc splashing and edge overcoating – problems that particularly affect the high-speed thin coating of steel sheets. We also design after pot cooling equipment installed with heating and cooling devices suited to the steel grade being processed.

For good anticorrosion performance, galvanized steelsheet is vastly applied into the industries of home appliance, decoration,advertisement, and civil construction, etc. Particularly, the home applianceindustry (outer shell of air conditioner, outer plate of refrigerator, outershell of washing machine, computer, and microwave oven, etc) and color coatedplate has large demands on galvanized plate.

The continuous hot-dip galvanized line is manufactured using cold-rolled steel coil which is coated with a thin layer of high grade zinc on both sides by hot dip zinc coating process. It resists corrosion by supplying barrier and cathodic protection, as well as through the development of the zinc patina. These three levels of corrosion protection provide galvanized steel with maintenance-free longevity for decades. JJRS not only manufacture and install equipment, but also carry out professional technical innovation to the galvanizing plants.
