custom flashing for the house.

[fat tony]

I need to make a custom flashing for my house. For reasons of economy, and to 'keep it real'  I decided to use 26 gauge galvanized sheet steel. Wrt to making the joints, I am thinking of either screwing the seams together with machine screws & nuts & bolts (non standard, I know), panel bond or some  type of epoxy, or soft soldering the seams together after folding them in place with a hand seamer.  Does anyone know off the top of their head, if there is a soft solder that will adhere to the zinc plating? I know there must be something out there like that, because I have gone through a couple of crates of CZ surplus 7.62X39 ammunition, and the inner box is heavy galvanized soft solderered at the seams. Best regards, Tony.

I think you will find lead will work if you flux with say Nokorode sodering paste . If it is in contact with surfaces that can catch on fire then it might be wise to use an iron instead of open flame.

Thanks, I tried it on a spot of the galvanized with regular 50/50 solder and acid paste flux, and it flowed and stuck beautifully. I will not have any problems if this is any indication. Thanks for the info Shootall.

I remember in highschool wood shop class(1981) they had a tin smithing portion where we all made galvanized steel toolboxes and dust pans useing folded seams and soft solder.
