I think it depends on the alloys used in the galvanizing.
How to solder galvanized gutters.
If you want to rivet tin surfaces first.
I own a rain gutter company and we routinely and easily solder our half round galvanized gutter.
The value of hot dip galvanizing stems from the relative corrosion resistance of zinc which under most conditions is considerably better than iron and steel.
I recommnbed rosin flux because any residue of acid chloride flux will rust em.
Galvanized gutters particularly the zinc coating on the gutter should hold up for decades before there are any signs of corrosion.
Beware look alike products like zap or zincalume these cannot be soldered either.
Super alloy 1 has a very low melting point which prevents the galvanized coating from burni.
A sharp point is needed to control the flow and direction of the solder especially on vertical joints.
Galvanized steel is a protected variety of the metal using the process of galvanization to prevent and repel corrosion.
They can be soldered at the joints or pop riveted and sealed with a seam sealer.
Soldering coated galvanized wire which is typically used for fencing guy wires or holding a support post in a permanent position requires that the two ends of the bare wires are clean and free of all debris so the solder can adhere to them properly the coating prevents corrosion of the wire which is generally used outdoors and is exposed to the elements.
For a pyramid tipped acetylene fueled soldering iron make sure that the tip is clean and that the four facets are flat and meet at a fine point.
However some galvanized sheet metal is impossible to solder.
However there are many objects in your home made of galvanized steel such as gutters panels or water tanks that can be improved by soldering.
Super alloy 1 can easily solder galvanized steel plates together.
Galvanized gutters are made from hot dip steel and have been effectively used for more than 150 years.
Soldering gutters video playlist.
Unlike welding soldering allows the user to bind small pieces of metal together and is commonly used in the manufacture of circuit boards.
I am putting galv sheeting on a garden work bench with l flashing on the edges.
Hi ted the first writer and i are interested in knowing how to solder galvanized materials like rain gutters.
Soldering galvanized requires vigorous abrasive cleaning.
Galvanized steel gutters will hold up in extreme cold and hot temperatures and are particularly popular in areas with snow and ice.
Aluminum gutters seem less physically robust than galvanized steel but i have never seen one fail by corrosion.
