I know a good guy, u can msg me and I'll pass on his number, no matter who you get b sure you get references and see actual work as big diff between stuff. I have gates done by another guy (at a good price and service was excellent) and then got this guy to do my railings (not cheap) but they look so much better that the gates due to size of bars and finish.
Also, get them treated (I forget the word) and get him to put the black stuff on them (its not paint)
"Galvanised" I think
