Re: Corrosion protection

I understand that hot-dip galvanize is the best to reduce corrosion for crs but it is harmful for the environment and very little to nothing available in the Northern California.
How will iron-phosphate conversion and powder coating perform instead?
Or any other treatment of crs for outdoor use to keep corrosion to minimum.
Will greatly appreciate any suggestion:confused:

Re: Corrosion protection

gday soma,if you want to powder coat substrate you should sand blast first too mechanicly etch surface then use the iron phosphate pre treatment,prime the substate with a zinc based powder then top coat with your prefered powdercoat colour you should get approx about 1000hrs in a salt spray test . to get a better salt spray result you might want to consider zinc phosphate pre treatment.
