Product Technique

Use the cold rolled strip steel and galvanized strip steel (electrogalvanizing and hot-dip galvanzing)as thebase metal, in the continuous set, our surface will be pre-processed(degreasing and chemical processing), with the method of the roller coating, paint one or more layer of liquid coating on the surface. After baking and cooling the plate, we can finally get the coated steel plate. As we can paint many different kinds of colors on it, customaily we call them color coated steel plate. 


Production Flow

Pay off reel → double cut shear → welder →notcher → entry accumulator→pre cleaning section→ furnace → hot bridle→ zinc pot→air knife →after cooler →water quench → dryer → skin pass mill → dryer → tension leveler → dryer → chemical coater → chemical oven → cooler → exit accumulator → oiler → exit shear → tension reel


Product Advantages:           

a. Light weight,beutiful took,excellent anti-corrosion performance.         

b. Acid&alkali resistant         

c. Excellent mechnical strenth,easily molding.         

d. Well coating adhesion,which can keep fresh colour for a long time
