Topic tags/keywords: question

I have a pergola ( gazebo).
On the top of it I have twenty 2×6 lying flat.
Because of the sun , the rain, the snow and so on, these get rapidly deteriorating.
I do not not want to have to climb on the pergola every year especially as I get older so,to protect them, I am getting galvanized steel caps made.
Question: which kind of screws should I use to secure these caps on the 2×6.
I am concerned about electrolysis.
Would Stainless steel be OK?
Thank you.

Use a standard galvanized siding screw with a rubber or nitrile seal.

Why aren’t you using regular roofing-siding painted metal.

Not criticizing, just curious

After a while paint peel or deteriorate

Siding metal isn’t usually painted any more, it is powder coated. That is more effective in stopping electrolysis than paint. It will also last for 50 years or more.

Thanks Dallas…..................so it sounds like we agree the metal sheeting is the way to go

MetalMart in Lehi sells a zillion tons of this stuff. Lots and lots of sales. The also have occasionally cut-offs that are very inexpensive if you can work with the color. Your total amount needed would not be too much of a factor anyway. They will even cut it to exact length for you, so little to no tin-snipping needed. VERY helpful folks as to install, etc

Bruce, i do not want to cover the all thing , only the 2×6,individually.
To cover the all thing would easier, faster and cheaper but this is not what I want to do.
Thanks anyway

Bert, most places that sell metal can get it in about any shape you can measure and draw. It will come preformed and all you do is add hole for the screws.

Okay, it’s a moot point now, but I was going to say, I don’t think electrolysis is much of a problem in the absence of an electrolyte, such as saltwater. If anyone with experience can refute this, I will stand corrected.

That is called Galvanic corrosion. Corrosion caused by using dissimilar metals. Bert is correct it will corrode when you do this. I think he is using the incorrect term but then again maybe not. Have a great evening.

They both need an Electrolyte to occur, Electrolytic Corrosion requires an applied current and Galvanic doesn’t.

If it is treated lumber, depending on the age, galvanized may be an issue.
