All
I did some searching and I can’t find it.
Someone did a picture thread on soldering glavanized steel within the last couple of months. I could find the one by slateman and he mentions the thread, but I can’t seem to find it.
I have to build a commercial gutter with galvanized steel and I wanted to read thru that thread.
I have done alot of sheet metal work and soldered alot of copper pipe, but I have never soldered glavanized sheet metal.
Thanks
Rich

Rich ,
Heres the one you're looking for I think .

Thanks for the prompt reply.
Seemed like that was buried where not many folks might see the responces
I found yours, (refered to above) but I thought someone did a thread about 1-2 weeks prior to that with pictures and step by step explaination.
I thought it was in the photo gallery.
I just need to prepare the metal with acid and try some test pieces.
I am alittle worried about expansion. It's a 36' run of 6" x 6"
I just found a thread by Sphere on making copper built in gutters. That's another project I may have in the works.
Our local sheet metal guy has terminal cancer and i don't know of anybody else that can do this, so I might have to tackle this one.

Rich ,
TH asked about it in another thread on some roofing topic , and I showed a few about soldering a chimney pan . Thats all the pics I have seen lately .
36 ' shouldn't need an expansion joint -- much longer and you might want one .
Put some questions out there when you're ready if you want some help .

Should I do my joints (8' long pieces) like this (Sphere's pic).

Or should I just lap them by 3-4 inches and then rivet.
I am assuming that I want to wash with acid wherever I want solder to flow to.
Do I use the same solder that i use for soldering copper pipes?
In one of the posts I found in search the OP mentioned painting the inside of the gutter (where he has soldered) with a special coating for galvanized to keep it from rusting.
Is that standard practice? Is rust more likely to occur where you solder?
With copper I always wipe the hot pipe down with cold water and a sponge of heavy clothe to clean the flux off the pipe. It produces a very clean looking joint and they seem to age better. I think the flux is corrosive to the copper if left on. And it washes off best when the pipe is hot.
Does this also apply to galv?
another thread on some roofing topic
Maybe I am dreaming or I saw it in JLC, but I thought I saw something about a week or 2 before your thread from someone I didn't recognize.
Thanks
Rich
Are you lining a box gutter or hanging gutter? Box gutter can be folded and locked because you can beat the folds tight, hanging just gets rivits and soldered.
You can use plumbing solder, but 50/50 is still better IMO. Yes the acid acts as a flux somewhat and preps the galv (zinc) for the solder to adhere.
I dunno about aany coatings, we never have used anything on new work.Spheramid Enterprises Architectural Woodworks

Project a is a 36' long box gutter with 26 ga galvanized, hung on the back side of a commercial building. drop on each end. EPDM rubber drops into it with term bar.
I am pretty sure the there is buffalo board under neath and the roof is fully adhered. But I don know if this gutter is part of the old roof with a flange running up the roof.
I was going to build the gutter on the ground and then install it.
Project #2 is not nailed down, but I would do this in copper. The HO has a patient who does welding who he thinks could dor the soldering. I don't know anything else about the guy. Like I said in an earlier post our long term sheet metal guy has terminal cancer. see pics below for project #2

They want me to work up an estimate to rebuild the soffit, fascia, roof and gutter framing. I may want to take a tab at building the gutters.

Rich,
The pics did not come up.
Chuck Slive, work, build, ...better with wood
Steven
They come up if you right click
In my county fair thread I have been having the same problem.
but it never happened on my screen. Well guess what?
The 1 st pic of the house came up and all the others were red x. LOL
Rich
Rich,
I got all of your epic county fair thread pics.
Still no pics here. Rt click or otherwise.

Pics didn't make it, but I get the drift.
Copper is (to me) easier and better, but I'm just that way from less exposure to galvanized. I also wouldn't see the benefit to ground assembly, just do it up on the roof where things can be seen more clearly as far as flow and any "hiccups". Maybe 2 8' ers on the ground, but not the whole thing.
Stuff happens when ya solder, things can warp or grow or twist a tad, and having some anchorage to the framing or roof or drip edge to clamp to helps keep it going as planned.Spheramid Enterprises Architectural Woodworks

Rich ,
The gutter you'll be using is free standing , not built into the woodwork like this picture . therefore lapping and rivetting will be fine .
Flux the seams with acid or a special flux from Johnsons if you want to .
I'd use 50 / 50 bar solder in half pound bars . Find some old hand irons in a flea market and a way to heat them well . Then it's just like getting to Carnegie Hall --- practice , practice , practice !!
Walter
Thanks for the answers.
My plumber has a soldering iron I can use( if he can find it) and his brake.
I have been using his brake for many years.
Rich
Rich ,
Soldering inside a gutter is a challenge at times if you have only one iron .
I usually have 3 or 4 different shaped iron tips so that corners , verticals ,and such are accesible . With only one iron you might experience some frustration .
Walter
Rich ,
I just threw a couple days of pictures into this album . A bunch of them show some good galvy soldering pics .

Thanks for the advice, I will look at the pics.
