Will aluminium react with gal?

admin

I'm pricing a staircase where the customer wants aluminium treads bolted onto steel stringers. Its an outdoor set of stairs so the stringers/risers are gal. My question is will the ally treads react with the gal? should I lay a strip of rubber in between the 2 to prevent contact?Thanks.

Reply:thanks dave, will do. I'll use anti-foul on the thread too, just to make sure. The aluminium treads are pre-fabbed and are supplied load rated.
