Galvanized painting pipes
WE ARE MANUFACTURING GALVANIZED PIPES FOR SPACE FRAME.AFTER GALVANIZING WE USE POWDER COAT PAINT FOR PAINTING.AFTER GALVANIZING OPERATION WE ARE USING CHEMICAL BATHS FOR THE PREPARATION TO PAINT.QUESTION IS HOW CAN WE ELIMINATE THESE CHEMICAL BATHS.WHAT WE CAN DO INSTEAD.CAN YOU GIVE US AN IDEA..THANKSMURAT AKSUT
Perhaps if the pipes was galvannealed the pretreatment would be simplified. But try to describe to us in what way the product can be improved (i.e. in what ways it is imperfect) rather than what steps you would like to eliminate to reduce costs. Pretreatment is done because it is important, and a campaign designed around simply leaving it out will almost surely be a failure. Good luck.
