Surely to say you've never had a chassis distort when galvanised CANNOT be true ? they will distort just putting them in the back of the van / truck whatever without the trauma of hot dip galvanising under their own weight.
I accept that they may not have distorted enough to cause you any trouble but I can assure you that they did distort !
